 errors at trial, plus a mistake in his Guidelines calculation, require a new trial

 and resentencing. We disagree and so, exercising our jurisdiction under 
28 U.S.C. § 1291
 and 
18 U.S.C. § 3742
(a), we affirm.

                                  BACKGROUND

 I.    Factual Background

       Two boys native to Grand Junction, Colorado were abused throughout

 their childhoods by the defendant, Michael Tracy McFadden. Both boys, known

 to us as J.W. and K.W., spent much of their youth playing and sleeping over at

 McFadden’s house. McFadden is distantly related to J.W. on J.W.’s mother’s

 side. McFadden and K.W. are unrelated, but McFadden was a close friend of

 the W. family. McFadden stepped up to help look after the boys because J.W.’s

 mother was battling addiction and an abusive relationship, while K.W.’s

 parents generally struggled to make ends meet. McFadden ingratiated himself

 with the boys and their families through his generosity. He provided necessities

 (clothing, food, rides to school, doctor appointments) and luxuries (BMX bikes,

 paintball guns, trampolines, videogames) that the boys’ families could not

 afford.

       J.W. lived with McFadden for the better part of six years, from roughly

 ages six to twelve. When J.W. was about eleven and K.W. was about ten, K.W.

 began regularly going over to McFadden’s house to play with J.W. and J.W.’s

 siblings. K.W. began spending most weekends there and would frequently stay

 the night. During these overnights, both boys slept with McFadden in his bed.

                                          2
Appellate Case: 23-1089   Document: 010111103175     Date Filed: 08/30/2024     Page: 3



 Once the boys would fall asleep, McFadden would assault them. When

 McFadden moved to a different home in Grand Junction, J.W. went with him,

 and K.W.’s family moved to a neighboring property. K.W. continued to spend

 significant time playing with J.W. and sleeping over at McFadden’s house. The

 same pattern of abuse continued there. To facilitate his abuse, McFadden

 routinely gave the boys melatonin in high doses before bedtime.

       Though McFadden’s Colorado homes were sites of repeated abuse,

 McFadden also assaulted both boys across state lines. McFadden was a truck

 driver, so he regularly traveled on interstate highways picking up and

 delivering loads. He often invited J.W. and K.W. to accompany him on these

 trips. On one such trip to Arizona, when J.W. was about nine, McFadden

 assaulted him during the night while J.W. slept next to McFadden on the

 mattress in the semi-truck’s sleeper cab. On another trip from Telluride, CO to

 Farmington, NM in December 2010, when J.W. was ten, McFadden once again

 assaulted J.W. while the two slept in the sleeper cab of McFadden’s semi-truck.

 Both times, McFadden penetrated J.W.’s anus while J.W. pretended to sleep.

 These assaults caused J.W. to feel pressure and a wet sensation in his rear.

       In December 2012, McFadden took K.W. and K.W.’s brothers on a semi-

 truck trip from Idaho to Nebraska. At the time, K.W. was eleven, his older brother

 (S.W.) was eighteen, and his younger brother (L.W.) was nine. S.W. slept across

 the driver and passenger seats, while K.W., L.W., and McFadden shared the

 mattress in the sleeper cab behind the front seats. During the night, McFadden

                                         3

 pulled down K.W.’s pants and inserted his penis into K.W.’s anus, which K.W.

 said “hurt a lot.” ROA vol. VI, at 183.

       Around the time of the Nebraska trip, other children started coming

 forward with allegations that McFadden had abused them. From these

 accusations, Detective Edward Prescott with the Grand Junction Police

 Department obtained a warrant to arrest McFadden, who was still with the W.

 boys in Nebraska. The local Nebraska police executed the warrant and arrested

 McFadden on January 3, 2013. The W. boys’ mother picked them up at a

 Nebraska truck stop and drove them back to Colorado. On the ride home,

 K.W.’s mother asked K.W. if McFadden had ever “done anything” to him, and

 K.W. said no. Once they returned to Colorado, K.W.’s mother arranged for

 K.W. to meet with a child counselor. That meeting was the first time K.W.

 accused McFadden of sexually abusing him. The next day, January 16, 2013,

 Detective Prescott conducted a forensic interview with K.W., during which

 K.W. detailed McFadden’s history of abusing him. That interview was recorded

 on video.

       The parties disagree about when J.W. first accused McFadden of sexual

 abuse. 1 McFadden insists that J.W. outcried before K.W. talked to Detective


       1
         The government has a motion pending before this court to supplement
 the record on appeal with an exhibit list from trial, which it contends will
 refute McFadden’s assertion that K.W.’s outcry was tainted by J.W.’s earlier
 admission of abuse. The government maintains that J.W. accused McFadden
 after K.W.’s interview on January 16, 2013, and so K.W.’s interview was
                                                               (footnote continued)

 Prescott, the government maintains that it was after. Regardless, J.W. came

 forward in early 2013 and told Detective Prescott that McFadden had been

 sexually abusing him for many years.

       Years later, in 2018, J.W. and K.W. were interviewed again about

 McFadden’s assaults. The FBI conducted K.W.’s interview during his stint at a

 juvenile correctional facility. The audio of that interview was recorded.

 II.   Procedural Background

       McFadden was convicted in Colorado state court on nineteen counts of

 child-sex abuse. 2 McFadden appealed that conviction and won. The Colorado

 Court of Appeals determined that McFadden’s speedy-trial rights had been

 violated, and so the court dismissed all charges. The Colorado Supreme Court

 denied certiorari, and McFadden was released. People v. McFadden, No.

 17SC573, 
2018 WL 827272
 (Colo. Feb. 12, 2018).




 untainted by his friend’s influence. McFadden opposes this motion. The
 government’s arguments do not compel us to exercise our power to supplement
 the appellate record. See United States v. Kennedy, 
225 F.3d 1187, 1191
 (10th
 Cir. 2000). Even if McFadden is correct that J.W.’s forensic interview occurred
 before K.W.’s, this does not impact our deferential review of the district
 court’s trustworthiness analysis under Rule 807(a)(1), see Discussion § I.A.1,
 infra. The exhibit list that the government seeks to admit would have no effect
 on our decision. The government’s motion is denied.
       2
         The Colorado Court of Appeals opinion and the entire state-court case
 record is sealed. See People v. McFadden, 2013-CR-27, 2013-CR-339, 2013-
 CR-342 (Mesa Cnty. Dist. Ct. 2015); People v. McFadden, No. 15CA1925

        About a year after his release, a federal grand jury charged McFadden

 with five criminal counts related to his sexual abuse of J.W. and K.W. across

 state lines. Counts One and Three were charged under 
18 U.S.C. § 2241
(c) for

 crossing state lines with intent to engage in a sexual act with a minor under the

 age of twelve, and Counts Two, Four, and Five were charged under 
18 U.S.C. § 2423
(a) for transportation of a minor with intent to engage in sexual activity.

        Before trial, the government filed a notice of intent to introduce the video

 recording from K.W.’s 2013 forensic interview with Detective Prescott under

 Federal Rule of Evidence 807, the residual exception to hearsay. In its notice,

 the government identified three recorded statements for admission at trial:

 (1) K.W.’s statement regarding McFadden’s assaults; (2) K.W.’s statement

 about the melatonin that McFadden gave him; and (3) K.W.’s statement that,

 one time, he saw McFadden touch J.W. under a blanket. The government

 argued that these statements met Rule 807’s requirements because the

 statements were “supported by sufficient guarantees of trustworthiness” and

 were “more probative,” given that K.W.’s 2013 statements were made closer in

 time to the alleged assaults. ROA vol. I, at 157–59. McFadden objected to the

 government’s notice. The district court then held a pretrial evidentiary hearing,

 in part to assess the 2013 video’s admissibility under Rule 807. After hearing

 arguments from both sides, the court reserved its ruling on the Rule 807 issue

 until trial.

Appellate Case: 23-1089   Document: 010111103175     Date Filed: 08/30/2024   Page: 7



       At trial, the government examined K.W. about the alleged assaults.

 Asking whether McFadden had penetrated K.W. with his penis, K.W. initially

 said that McFadden had “tried to.” ROA vol. VI, at 182–83. The government

 zeroed in: “When you say he tried to put his penis in you, did he put his penis

 into your butt?” 
Id. at 183
. K.W. then answered, “Yes.” K.W. further confirmed

 that, “Yes,” he felt pressure against his anus from McFadden and that it “hurt a

 lot” “because [he] was little at the time.” 
Id.
 In testifying about the Nebraska

 semi-truck trip, K.W. said that he “slept right next to Mike” and identified the

 government’s exhibit (a photo of the semi-truck’s sleeper cab mattress) as the

 location where McFadden penetrated him. 
Id. at 187
.

       After this testimony, the government moved under Rule 807 to admit the

 2013 forensic-interview video recording, in which K.W. makes more direct

 statements to Detective Prescott about McFadden’s penetrative assault. The

 district court admitted the evidence under Rule 807. The court agreed with the

 government that Rule 807’s admissibility requirements were satisfied and that

 “[i]t was apparent that [K.W.] only answered with prompting and he was

 equivocal about the penetration, which he was not in the video.” 
Id. at 195
.

 Concluding that “the video evidence is more probative on the point for which it

 is offered than any other evidence that the Government can obtain through

 reasonable efforts,” the court admitted the video recording. 
Id.
 McFadden

 objected. Over McFadden’s objection, the jury was shown the 2013 video

 recording of K.W.’s forensic interview, but the video was not given to the jury

                                         7
Appellate Case: 23-1089   Document: 010111103175     Date Filed: 08/30/2024   Page: 8



 to use during deliberations. A transcript of the interview was distributed to the

 jury as an aid while they watched the video, but the transcript was not given to

 the jury to reference during deliberations.

       After the jury watched the 2013 video recording, K.W. was cross-

 examined by defense counsel. During cross, defense counsel used the transcript

 from K.W.’s 2018 FBI interview to impeach him. Defense counsel then moved

 to admit the audio recording of K.W.’s 2018 interview with the FBI. The court

 denied the defense’s motion because, unlike the government, defense counsel

 had given no notice of his intent to introduce Rule 807 evidence. So the court

 rejected the 2018 audio recording as inadmissible hearsay.

       Over the course of McFadden’s five-day trial, the jury heard testimony

 from the following witnesses: J.W.; J.W.’s mother; K.W.; K.W.’s mother; S.W.

 (K.W.’s older brother); two of McFadden’s former bosses from the construction

 company and trucking company where he worked; the Nebraska police officer

 who arrested McFadden; Detective Prescott; Sue Goebel, the nurse who

 performed a SANE (sexual assault nurse examiner) exam on J.W. in March

 2013; and a child therapist who offered expert testimony about the

 psychological impact of sexual abuse on children. Most of this testimony is

 unchallenged on appeal, except for two instances of alleged vouching, which

 we discuss later in this opinion.

       The jury found McFadden guilty on all counts, and the district court

 sentenced McFadden to serve concurrent life sentences on each count. The

                                         8
Appellate Case: 23-1089   Document: 010111103175     Date Filed: 08/30/2024   Page: 9



 presentence report calculated McFadden’s sentence by splitting the five

 convicted counts into two groups, one for each child victim. Counts One and

 Two, based on the abuse of K.W. in Nebraska comprised the first group, and

 Counts Three, Four, and Five, based on the abuse of J.W. on the trips to

 Arizona and New Mexico comprised the second group. The base level for each

 group was 28, according to U.S.S.G. § 2G1.3(a)(3), the guideline for violations

 of 
18 U.S.C. § 2423
(a). The base level was then increased by 14 levels under

 various specific offense characteristics. McFadden challenges one of these

 increases on appeal, the two-level enhancement imposed under

 § 2G1.3(b)(2)(B) for “unduly influenc[ing] a minor to engage in prohibited

 sexual conduct.” McFadden timely appealed his conviction and sentence.

                                  DISCUSSION

       McFadden contends that multiple errors committed at trial demand

 reversal of his conviction and that an error in his Guidelines calculation

 requires resentencing. We agree with McFadden that the district court erred in

 admitting the 2013 forensic-interview video recording under Rule 807, but this

 error was harmless. Because the district court made no other errors, we affirm.

 I.    Rule 807

       The residual-hearsay exception under Rule 807 is a catchall to the

 recognized hearsay exceptions housed in Rules 803 and 804—present sense

 impressions, excited utterances, and the like. See Idaho v. Wright, 
497 U.S. 805, 817
 (1990) (explaining that the residual rule “accommodates ad hoc

                                         9
Appellate Case: 23-1089    Document: 010111103175      Date Filed: 08/30/2024      Page: 10



  instances” where a statement may not “otherwise fall[] within a recognized

  hearsay exception” but is “nevertheless . . . sufficiently reliable to be

  admissible at trial”).

        Rule 807 states:

        (a)    In General. Under the following conditions, a hearsay
               statement is not excluded by the rule against hearsay even if
               the statement is not admissible under a hearsay exception in
               Rule 803 or 804:

               (1)   the statement is supported by sufficient
                     guarantees of trustworthiness—after considering
                     the totality of circumstances under which it was
                     made and evidence, if any, corroborating the
                     statement; and

               (2)   it is more probative on the point for which it is
                     offered than any other evidence that the
                     proponent can obtain through reasonable efforts.

        (b)    Notice. The statement is admissible only if the proponent
               gives an adverse party reasonable notice of the intent to offer
               the statement—including its substance and the declarant’s
               name—so that the party has a fair opportunity to meet it. The
               notice must be provided in writing before the trial or hearing—
               or in any form during the trial or hearing if the court, for good
               cause, excuses a lack of earlier notice.

  Fed. R. Evid. 807 (emphasis added).

        “The residual exception ‘should be used only in extraordinary

  circumstances.’” United States v. Burgess, 
99 F.4th 1175, 1183
 (10th Cir. 2024)

  (quoting United States v. Dalton, 
918 F.3d 1117, 1133
 (10th Cir. 2019)). Such

  circumstances exist when the court is “satisfied that the evidence offers

  guarantees of trustworthiness and is material, probative and necessary in the


                                           10

  interest of justice.” 
Id.
 (quoting Dalton, 
918 F.3d at 1133
). We interpret the

  residual exception with “caution” so that it does not “swallow the entirety of

  the hearsay rule.” United States v. Hammers, 
942 F.3d 1001, 1011
 (10th Cir.

  2019).

        McFadden argues that the district court abused its discretion in applying

  Rule 807 to two pieces of evidence offered at trial: (1) a video recording of

  K.W.’s 2013 forensic interview with Detective Prescott, introduced by the

  government; and (2) an audio recording of K.W.’s 2018 interview with the FBI,

  offered by the defense. Under Rule 807, the district court admitted the 2013

  video recording but excluded the 2018 audio recording. McFadden contends

  both rulings were error.

        We review such evidentiary decisions for an abuse of discretion. United

  States v. Hay, 
95 F.4th 1304, 1318
 (10th Cir. 2024). We do so recognizing that

  a legal error constitutes an abuse of discretion per se. United States v. Geddes,

  
71 F.4th 1206
, 1214 (10th Cir. 2023). “[L]egal conclusions about the Federal

  Rules of Evidence” are subject to de novo review. Hay, 
95 F.4th at 1318
.

        A.    The 2013 Video Recording

        To be admissible under the residual-hearsay exception, the offered

  evidence must contain “sufficient guarantees of trustworthiness” and be “more

  probative on the point for which it is offered than any other [reasonably

  attainable] evidence.” Fed. R. Evid. 807(a). “[T]he party offering the evidence

  bears” the “heavy burden” of showing that both prongs are met. United States

                                          11
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 12



  v. Trujillo, 
136 F.3d 1388, 1396
 (10th Cir. 1998). The government offered the

  2013 video recording, so it bore the burden of satisfying Rule 807’s two-

  pronged admissibility standard. See id.

              1.     The district court’s ruling on trustworthiness was not
                     error.

        In child-sex-abuse cases, there are various factors that courts consider in

  deciding whether a child victim’s hearsay statement is admissible under Rule

  807. See Wright, 
497 U.S. at 821
. These include spontaneity, consistency

  between repeated allegations, mental state of the child, use of age-appropriate

  terminology, and lack of motive to fabricate. United States v. Tome, 
61 F.3d 1446
, 1452–53 (10th Cir. 1995) (citing Wright, 
497 U.S. at 821
). Rule 807 also

  instructs courts to evaluate “the totality of circumstances under which [the

  statement] was made.” Fed. R. Evid. 807(a)(1). A totality analysis might

  implicate the training and expertise of the interviewer, the interviewer’s use of

  open-ended rather than leading questions, the time between the alleged abuse

  and the hearsay statements, and the declarant child’s age. 3 See Tome, 
61 F.3d at 3
           After the 2019 amendments to Rule 807 (formerly Rule 803(24)) we
  should also consider corroborating evidence that bolsters the trustworthiness of
  a hearsay statement. Fed. R. Evid. 807(a)(1); see Burgess, 
99 F.4th at 1184
 n.5
  (supplanting Tome’s rule “that corroborating evidence d[oes] not bear on the
  trustworthiness of a hearsay statement” because “the 2019 amendments to Rule
  807 . . . specifically require the court to consider corroborating evidence in the
  trustworthiness enquiry” (cleaned up)). But in this case there is no such
  evidence. The government argues that S.W.’s testimony “corroborat[ed]
  [K.W.’s] account of the sleeping arrangements” in the semi-truck and K.W.’s
  recollection that “(S.W.) did not wake up during the night.” ROA vol. I, at 158.

  1453; see also United States v. Farley, 
992 F.2d 1122, 1126
 (10th Cir. 1993)

  (affirming that the hearsay testimony was admissible under Rule 807 because

  the child spoke to her mother about the alleged assault within a day of the

  incident, the child was “still suffering pain and distress from the assault” when

  she spoke about it, and the child’s “youth” favored reliability (citation

  omitted)). Together, these factors guide the determination for whether the child

  was “particularly likely to be telling the truth when the statement was made.”

  Tome, 
61 F.3d at 1453
 (quoting Wright, 
497 U.S. at 822
). The goal is to ensure

  that a child’s hearsay statement admitted under the residual-hearsay exception

  carries the same “particularized guarantees of trustworthiness” that would

  attend any other hearsay statement admissible under a “firmly rooted” hearsay

  exception. Wright, 
497 U.S. at 821
.

        The government’s notice of intent gave several reasons why K.W.’s 2013

  video statements were sufficiently trustworthy: (1) the consistency of K.W.’s

  statements about the assaults; (2) the interview’s proximity in time to the

  alleged Nebraska assault (about two weeks); (3) K.W.’s use of childlike

  terminology (i.e., describing penises and anuses as “no-no’s”); (4) K.W.’s



  But that testimony doesn’t corroborate the assault, and it doesn’t lend any
  greater reliability to K.W.’s story. In fact, McFadden argued at trial that S.W.’s
  testimony credited his version of events because, in McFadden’s view, it’s
  unrealistic that S.W. could have been sleeping mere feet away from McFadden
  and the younger brothers and yet not have heard or seen any of signs of abuse.
  For these reasons, we don’t view S.W.’s testimony as corroborative evidence
  that must be considered in the trustworthiness inquiry.

  particular and detailed descriptions of the assaults; (5) K.W.’s lack of

  motivation to fabricate; and (6) the interview being recorded on video, which

  allowed the jury to assess K.W.’s credibility. 4 And at the pretrial evidentiary

  hearing, the government presented testimony from Detective Prescott to explain

  the trustworthy circumstances under which he conducted K.W.’s forensic

  interview.

        The district court was particularly persuaded by Detective Prescott’s

  testimony. In issuing its ruling at trial, the court observed that “Detective

  Prescott went through his experience, his training on forensic interview

  techniques,” and his “attempt[] to determine that the witness [knew] the

  difference between a truth and a lie.” ROA vol. VI, at 195. From those

  observations, the district court concluded that the 2013 video “weighs in favor

  of a finding of trustworthiness.” 
Id.
 The court added that it had “carefully

  reviewed the video in light of relevant facts . . . under Rule 807 and Idaho v.

  Wright, 
497 U.S. 805
.” 
Id.
 The court then ruled that the 2013 video was

  sufficiently trustworthy under Rule 807(a)(1).




        4
          In its response brief, the government again makes the point that K.W.’s
  2013 forensic interview is more trustworthy because it was recorded. Neither
  Wright nor Tome list the recording of a statement as a factor that bears on its
  trustworthiness. We agree with other courts that have found this detail
  unpersuasive. See, e.g., United States v. Bruguier, 
961 F.3d 1031, 1033
 (8th
  Cir. 2020) (“Although a recording ensures a declarant’s statement is faithfully
  reproduced, it provides little assurance that the statement was truthful and
  reliable when spoken.”).

        Properly admitting a child’s hearsay statement under the catchall

  exception requires the district court “not . . . merely to find an absence of

  evidence that the statement was unreliable,” but to find that the child “was

  particularly likely to be telling the truth.” Burgess, 
99 F.4th at 1184
 (citation

  omitted). Though the court has “leeway” in considering the “appropriate

  factors” in its Rule 807(a)(1) analysis, it must consider those “factors [that]

  relate to whether the child declarant was particularly likely to be telling the

  truth.” Wright, 
497 U.S. at 822
. Once the court identifies the relevant factors,

  given the facts and arguments before it in a particular case, the court must then

  decide whether those factors unequivocally demonstrate the statement’s

  trustworthiness. See Tome, 
61 F.3d at 1453
. If the “circumstances surrounding

  [a child’s] statement . . . are equivocal” as to trustworthiness, then the

  “statement [is] . . . inadmissible hearsay.” 
Id.

        “[H]earsay determinations are particularly fact and case specific,” so “we

  afford heightened deference” to the district court’s evidentiary rulings to admit

  hearsay evidence. United States v. Lovato, 
950 F.3d 1337, 1341
 (10th Cir.

  2020) (quoting Trujillo, 
136 F.3d at 1395
). Because the district court stated that

  it considered the “relevant facts . . . under Rule 807 and Idaho v. Wright,” ROA

  vol. VI, at 195, before it admitted the 2013 video, we take the court at its word,

  see Lovato, 
950 F.3d at 1341
. Under this highly deferential review, the district

  court did not err in determining that the 2013 video carried sufficient

  guarantees of trustworthiness under Rule 807(a)(1).

        But we would be remiss not to point out that the district court’s reasoning

  in ruling on the government’s Rule 807 motion was wanting. Before admitting

  the video, the court should have made findings on the record for each of the

  relevant factors under Wright/Tome that it considered in evaluating the video

  statements’ trustworthiness. The district court is not typically “required to

  make a finding on the record as to each of the Rule 807 [factors],” but only so

  “long as the record demonstrates that the district court considered the relevant

  factors.” United States v. Smith, 
591 F.3d 974, 980
 (8th Cir. 2010) (emphasis

  added). And especially “[w]hen a statement is admitted under the catchall, the

  court should make an on-the-record finding that the requirements [of Rule 807]

  have been satisfied.” 5 Christopher B. Mueller & Laird C. Kirkpatrick, Federal

  Evidence § 8:140 (4th ed.) (August 2023 update); see United States v. Palacios,

  
556 F.2d 1359
, 1363 n.7 (5th Cir. 1977) (“The [Senate Judiciary] Committee

  . . . stated that the special facts and circumstances which lead the trial judge to

  allow an exception under Rule 803(24) [(now 807)] should be stated in the

  record.”).

        At the pretrial hearing, the court enunciated the cluster of factors

  pertinent to Rule 807(a)(1)’s trustworthiness inquiry, including spontaneity and

  use of age-appropriate language, but then declined to address these factors in

  its ruling on the record. This omission would be more acceptable if the record

  absolutely supported the court’s decision to admit the video. See Smith, 
591 F.3d at 980
; see, e.g., Burgess, 
99 F.4th at 1184
 (recognizing that, even beyond

                                          16
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024     Page: 17



  the “relevant” factors that the district court considered in assessing

  trustworthiness, “other guarantees of trustworthiness” were apparent from the

  record that additionally supported the court’s ruling). But here, those factors

  weigh against the video’s trustworthiness, and yet the court offered no analysis

  or findings on these points. It instead confined its discussion to Detective

  Prescott’s experience, the nature of his interview techniques, and his efforts “to

  determine that the witness did know the difference between a truth and a lie.”

  ROA vol. VI, at 195. Based on that, the court found that “K.W.’s statement

  [wa]s supported by sufficient indicia of reliability such as to be admissible with

  respect to the first prong of the Rule 807 inquiry.” 
Id.
 at 195–96. Our concern

  is that most forensic interviews will likely be conducted by qualified law-

  enforcement agents, trained to ask the right questions in the right way so as to

  render every forensic interview inherently trustworthy by the district court’s

  standards. The court focused almost singularly on these elements of K.W.’s

  2013 interview, without paying equal mind to the factors that diluted its

  trustworthiness. See, e.g., Tome, 
61 F.3d at 1453
 (weighing equally the factors

  that supported and the factors that undermined the hearsay statement’s

  trustworthiness). From our perspective, several factors potentially subverted the

  trustworthiness of the 2013 video statements, which the district court never

  addressed on the record.

        First, K.W.’s statements to Detective Prescott were not spontaneous.

  K.W. knew that the purpose of the interview was to talk about McFadden’s

                                          17
Appellate Case: 23-1089   Document: 010111103175     Date Filed: 08/30/2024    Page: 18



  inappropriate behavior with children. And unlike the child victim in Burgess,

  K.W. never made any spontaneous allegations about McFadden’s abuse before

  his interview. See 
99 F.4th at 1184
 (affirming the admissibility of Rule 807

  evidence partly because the child’s recorded statements were consistent with

  spontaneous admissions she had made before the forensic interview). When a

  child is brought into a forensic interview knowing that the purpose of the

  interview is to discuss alleged abuse, this court has concluded that those

  interview statements lack spontaneity. See Tome, 
61 F.3d at 1453
 (noting that

  the child’s statement to a caseworker wasn’t spontaneous because the child

  knew the purpose of the meeting was to talk about “what defendant had done to

  her”). And the government doesn’t contest that K.W.’s 2013 statements lacked

  spontaneity.

        Second, though K.W. used some age-appropriate terminology in his

  descriptions of McFadden’s assaults, he also used sophisticated language

  beyond his years—for instance, stating that McFadden has “a disease and it

  makes him like little children” and that McFadden was “overdosing” the

  children with melatonin. ROA vol. I, at 171, 193. Not only does some of

  K.W.’s language suggest adult intervention, but the record substantiates that

  K.W. spoke with several adults about McFadden before his interview with

  Detective Prescott, including his mother and a child counselor. This type of

  intervention could undermine the trustworthiness of a child’s out-of-court

  statements. See United States v. Barrett, 
8 F.3d 1296, 1300
 (8th Cir. 1993)

                                         18
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 19



  (instructing the district court to consider on remand whether evidence of “prior

  interrogation, prompting, or manipulation by adults” of the child victim

  impacted the spontaneity of the child’s admission of abuse, making spontaneity

  “an inaccurate indicator of trustworthiness” (citation omitted)). More still, the

  taint of adult influence was McFadden’s principal argument against the video’s

  admission in his objection to the government’s notice of intent and at the

  pretrial evidentiary hearing, yet the court didn’t address this point in ruling on

  the motion at trial. We can’t know for sure which aspects of K.W.’s video

  statements were genuine and which, if any, were the product of outside adult

  influence. But it was the district court’s job to grapple with that possibility on

  the record as it “relate[d] to whether [K.W.] was particularly likely to be telling

  the truth.” Wright, 
497 U.S. at 822
.

        Third, the government stated in its notice of intent that the consistency

  between K.W.’s 2013 interview statements and his state-trial testimony make

  the video statements more reliable. But that analysis mistakes how we apply the

  consistency factor under Wright/Tome. In United States v. Harrison, we found

  that a child’s accusations about her abusive step-father were “consistent”

  because the child’s three separate allegations (two to law enforcement officers

  and one to a doctor) after the incident all conveyed the same story. 
296 F.3d 994
, 996–99 (10th Cir. 2002). So too in Burgess, we deemed the child’s

  statements “consistent” because her spontaneous admissions about the abuse to

  a trusted adult matched the statements she made to her mother the next day, as

                                          19
Appellate Case: 23-1089   Document: 010111103175     Date Filed: 08/30/2024   Page: 20



  well as the statements she made in a forensic interview conducted three days

  later. 
99 F.4th at 1179, 1184
. In both cases, we limited our consideration of the

  child’s consistency to the time “when the [hearsay] statement was made.” 
Id.

  (quoting Tome, 
61 F.3d at 1453
).

        Contrary to the government’s theory, K.W.’s consistency between his

  2013 forensic interview and his 2015 state-trial testimony is irrelevant.

  Testimony that K.W. gave two years after the interview has no bearing on the

  circumstances that existed when K.W. made his accusations in 2013. See Tome,

  
61 F.3d at 1453
. For that matter, the record contains no other accusatory

  statements from K.W. in the days around his 2013 interview from which we

  might gauge the consistency of his accusations against McFadden. K.W. and his

  mother both testified that he did not accuse McFadden of assault on the ride

  back from Nebraska, and any statements K.W. made to the child counselor the

  day before his forensic interview are not in the record. So we cannot say

  whether K.W. was consistent or inconsistent when he accused McFadden in

  January 2013. And without any reasoning from the court explicitly addressing

  Tome’s consistency factor, it’s unclear whether the court accepted the

  government’s erroneous arguments when it decided to admit the video. If it did,

  then that acceptance would have been error.

        We recognize that many factors favor the video’s trustworthiness—

  K.W.’s lack of motive to fabricate; Detective Prescott’s training and interview

  style; K.W.’s detailed statements about the abuse; and the short time gap (two

                                         20
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024      Page: 21



  weeks) between the last alleged abuse and the forensic interview—though the

  district court failed to mention most of these in its ruling. This balance of

  factors allows us to imagine how the district court arrived at its conclusion to

  find the video sufficiently trustworthy. But the absence of a record weighing

  the “appropriate factors” in this case hampers our ability on appeal to

  determine whether Rule 807 was correctly applied. Wright, 
497 U.S. at 822
.

        Tome doesn’t command merely that a majority of the factors signal

  trustworthiness. Its standard is even higher: Tome instructs that the

  circumstances surrounding the offered hearsay statement must be

  “[un]equivocal” such that its trustworthiness is “guarantee[d].” 
61 F.3d at 1453
. “[A] suggestion of trustworthiness cannot suffice.” Harrison, 
296 F.3d at 1006
. Our intolerance for equivocality in this arena echoes the extreme caution

  with which we apply Rule 807. The district court’s perfunctory statement about

  having considered the “relevant facts” under Rule 807 and Wright leaves us

  doubtful that the appropriate level of caution was exercised here. ROA vol. VI,

  at 195. Going forward, district courts assessing child hearsay statements in sex-

  abuse cases would do well to articulate their reasoning on the record for each of

  the pertinent trustworthiness factors before admitting out-of-court statements

  under Rule 807’s catchall exception to the rule against hearsay.

        Regardless, we resolve next that the 2013 video was not more probative

  on the point for which it was offered compared to other reasonably attainable



                                          21
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024      Page: 22



  evidence. So we conclude that the court’s admission of the hearsay evidence

  was error on that ground.

               2.     The 2013 video was not more probative on the point for
                      which it was offered.

        Rule 807’s second prong requires that an admissible residual-hearsay

  statement be “more probative on the point for which it is offered than any other

  evidence that the proponent can obtain through reasonable efforts.” Fed. R.

  Evid. 807(a)(2). We begin with the point for which the government offered the

  2013 video evidence.

        In its notice of intent, the government asserted that the 2013 video was

  more probative on three points: (1) McFadden’s penetrative assault of K.W.;

  (2) McFadden’s administering melatonin to K.W.; and (3) K.W.’s observing

  McFadden assault J.W. under a blanket. Then, at the pretrial evidentiary

  hearing, the government argued that because K.W. had “professed either a lack

  of memory of the incident or . . . a very strong desire to not talk about the

  incident” when he was interviewed in 2018, the government anticipated that

  K.W. would not be “present at trial” to testify. Suppl. ROA vol. I, at 36. The

  suggestion being that the 2013 video would provide the most probative, if not

  the only, available evidence as to all the points the government had raised in its

  notice of intent.

        But against the government’s expectations, K.W. did testify at trial and

  did recall the pertinent events. So when the government moved at trial to admit


                                          22
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 23



  the video recording, the court asked: “In light of the fact that [K.W.] testified

  that he did remember the truck assault, what is the purpose of the video?” ROA

  vol. VI, at 193. The government answered that the video “remains the most

  probative evidence on that point”—“that point” being the “truck assault”—

  because “K.W., while he did discuss the events in question, did so reluctantly

  and often after . . . prompting.” 
Id.
 Most concerning to the government was

  K.W.’s being “pretty equivocal about penetration,” which he was not in the

  video. Id. at 194. The government added that the video “is closer in time to the

  events in question.” Id. at 193. Defense counsel objected because K.W. “was

  able to recall the events” and therefore that there was no purpose for admitting

  the video. Id. The district court agreed with the government that K.W.’s trial

  testimony was “reluctant” and “equivocal about the penetration, which [K.W.]

  was not in the video.” Id. at 195. On that basis, the court ruled that the 2013

  video was “more probative on the point for which it is offered than any other

  evidence that the Government can obtain through reasonable efforts.” Id.

         The government maintains on appeal that the 2013 video was the more

  probative, reasonably available evidence to prove two points: anal penetration

  and K.W. observing McFadden jerk his hand away from J.W.’s penis under a

  blanket. 5


         5
          We decline to address the government’s third argument from the notice
  of intent—that the video was more probative proof of McFadden’s
  administering melatonin to K.W. After the notice of intent was filed, the
                                                             (footnote continued)
                                          23
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 24



        We can quickly dispense with the second point. The government argues

  that the video was more probative of whether K.W. witnessed McFadden

  touching J.W. inappropriately because, when the prosecutor asked K.W. at trial

  “whether K.W. saw ‘McFadden do anything to anyone else that made [him]

  uncomfortable,’ K.W. answered: ‘I did not, no.’” Resp. Br. at 30 (quoting ROA

  vol. VI, at 189). A vague question about K.W.’s discomfort was a feeble

  attempt to elicit testimony about one specific incident of alleged assault from a

  man who experienced years of abuse throughout his childhood. Rule 807(a)(2)

  requires the proponent of the hearsay evidence to exercise “reasonable efforts”

  to procure alternative evidence before resorting to the catchall rule. K.W. was

  an available witness, and yet the government did not ask him directly about the

  incident to which it now refers. This is not the sort of reasonable effort that we

  expect from the government to obtain nonhearsay evidence. Cf. United States v.

  Nucera, 
67 F.4th 146, 171
 (3d Cir. 2023) (affirming the district court’s decision

  to exclude an out-of-court statement, in part, because the declarant “was

  available to testify” and yet not called as a witness, “and his in-court testimony


  government never again raised that ground for probativeness before the district
  court, neither at the pretrial evidentiary hearing nor at trial, and the government
  has explicitly abandoned that point in its briefing to this court on appeal.
  Regardless, we would not find that argument persuasive of the video’s
  admissibility under Rule 807(a)(2) because K.W. testified at trial that
  McFadden regularly supplied him and the other children with melatonin. His
  live testimony about the melatonin is more probative than the out-of-court
  video statements. See United States v. W.B., 
452 F.3d 1002
, 1005–06 (8th Cir.
  2006) (establishing that a child victim’s in-court testimony is “generally more
  probative” than hearsay statements).

Appellate Case: 23-1089   Document: 010111103175       Date Filed: 08/30/2024     Page: 25



  . . . would have been more probative on th[e] point”); see also Mueller &

  Kirkpatrick, Federal Evidence § 8:142 (explaining that “more effort is expected

  of the government than of the accused” in demonstrating reasonable efforts

  under Rule 807(a)(2) and “more effort is expected if other evidence”—like live

  testimony—“would be superior to a statement offered under the catchall”).

        As to the point about anal penetration, K.W. testified sufficiently to this

  at trial. On direct examination, the government asked K.W. whether McFadden

  penetrated him, and K.W. responded that McFadden had “tried to.” ROA vol.

  VI, at 183. The government clarified whether “tried to” meant that

  “[McFadden] tried to put his penis in [K.W.],” specifically whether McFadden

  “put his penis into [K.W.’s] butt.” Id. To that, K.W. answered, “Yes.” Id. K.W.

  added that he felt pressure against his anus from McFadden’s penetration which

  “hurt a lot” “because [he] was little at the time.” Id.

        It is axiomatic that the Federal Rules of Evidence favor live testimony

  over statements made outside the courtroom. See Harrison, 
296 F.3d at 1007
.

  This is especially true “[w]hen the ‘key factual issues’ at trial turn on the

  ‘credibility’ and ‘demeanor’” of the witnesses. Garcia-Martinez v. City & Cnty.

  of Denver, 
392 F.3d 1187, 1191
 (10th Cir. 2004). Even in child-sex-abuse

  cases, where “exceptional circumstances generally exist” to admit residual-

  hearsay evidence, “a child’s in-court statements are generally more probative

  than a child’s out-of-court statements.” United States v. W.B., 
452 F.3d 1002
,

  not make Rule 807’s probativeness prong a guarantee, particularly when the

  victim has testified at trial. Cf. United States v. Balfany, 
965 F.2d 575, 582
 (8th

  Cir. 1992) (determining that, even though an adult’s hearsay testimony

  “included some facts that the testimony of [the child] and the other witnesses

  did not,” the hearsay statements were still less probative than the child’s live

  trial testimony which was “very comprehensive”).

        K.W. and J.W.’s credibility shoulders the government’s case because no

  one else bore witness to the alleged assaults. In this he said/he said case, the

  jury’s ability to assess K.W.’s credibility from live testimony was paramount.

  See Garcia-Martinez, 392 F.3d at 1191–92. Because the 2013 video statements

  are not superior to K.W.’s live testimony, there was no justification to override

  our preference for in-court testimony. See 2 McCormick on Evidence § 324

  n.39 (8th ed.) (July 2022 update) (explaining circumstances when an “out-of-

  court statement will be superior” to live testimony, including when a witness’s

  trial testimony is “incomplete[]”).

        Our most recent dispatch on Rule 807 and child hearsay statements offers

  a helpful contrast. In Burgess, we ruled that the video recording of a child’s

  forensic interview was admissible under Rule 807 because the recorded

  statements were more probative than the child’s trial testimony on a

  determinative issue of fact. 99 F.4th at 1185–87. Burgess contained nearly

  identical facts to the ones we confront now: a child accused a trusted adult of

  illegal sexual contact, the child testified to this contact at the accused’s

                                           26
Appellate Case: 23-1089   Document: 010111103175       Date Filed: 08/30/2024   Page: 27



  criminal trial, and the government additionally sought to introduce the video

  recording of the child’s forensic interview under Rule 807. See id. 1179–82.

  But Burgess contained one key difference—the child’s testimony differed from

  the original accusation that she made during her forensic interview. See id. at

  1182. In the interview, the child alleged that the defendant committed different

  sexual acts than those she testified to at trial. Id. at 1186. Given this

  inconsistency, we affirmed the trial judge’s “discretion to permit hearsay

  testimony” to “determin[e] that the recorded interview was ‘more probative on

  the point for which it [wa]s offered’—what sex acts [the defendant] committed

  against [the child].” Id. at 1187. We found support for this decision in several

  other circuit cases where courts have deemed out-of-court statements to be

  admissible residual hearsay, even though the child testified at trial, because the

  child’s testimony was inconsistent or unclear compared to the hearsay

  evidence. See id. at 1186–87 (citing Harrison, 296 F.3d at 995–96, 1000, 1003–

  07; W.B., 
452 F.3d at 1004
; United States v. Peneaux, 
432 F.3d 882, 887
, 891–

  93 (8th Cir. 2005); United States v. Wandahsega, 
924 F.3d 868, 874
, 881–82

  (6th Cir. 2019)).

        In contrast, K.W.’s trial testimony reflects his original allegation from

  the 2013 video accusing McFadden of anal penetration. When asked directly at

  trial whether McFadden inserted his penis into K.W.’s anus, K.W. responded,

  “Yes.” ROA vol. VI, at 183. And he even elaborated that the act “hurt a lot”

  due to his age and size. 
Id.
 K.W. also identified the government’s exhibit—a

  photo of the sleeper cab’s mattress—as the location where McFadden

  penetrated him. Though we generally afford the district court “a deferential

  standard of review” due to the court’s ability “to watch and listen to the

  witnesses as they testified,” we disagree that the 2013 video was more

  probative than K.W.’s live testimony about the alleged incident in the semi-

  truck. Burgess, 
99 F.4th at 1187
 (quoting Peneaux, 
432 F.3d at 893
).

        The government insists that K.W.’s trial testimony was ambivalent,

  making the 2013 interview more probative and necessary to prove penetration.

  McFadden responds that, even if the trial evidence weren’t probative enough to

  show penetration—though he believes it was—a conviction under 
18 U.S.C. § 2241
(c) does not necessarily require proof of penetration. The government

  acknowledges this but adds that, without penetration, the government would

  have “had to prove the additional element,” Resp. Br. at 30, of intention to

  “abuse, humiliate, harass, degrade, or arouse or gratify the sexual desire” of

  K.W, 
18 U.S.C. § 2246
(2) (providing four definitions for a “sexual act”

  punishable under 
18 U.S.C. § 2241
(c)). The government maintains that it was

  not obliged to add to its burden in this way. Even if we accept that the

  government needed to prove penetration as an element of the charged crime, the

  forensic-interview video was not more probative for that purpose. We disagree

  with the government that K.W.’s initial statement that McFadden had tried to

  penetrate him made his testimony unclear as to whether penetration occurred.

  In a follow-up answer, K.W. immediately explained what he meant.

                                         28

        A victim’s tepid trial testimony does not justify admitting more zealous,

  yet consistent, statements under the residual-hearsay exception. Were that true,

  Rule 807’s purportedly stringent admissibility standard would wilt. See Dalton,

  
918 F.3d at 1133
 (reserving Rule 807 hearsay admissions for “extraordinary

  circumstances”). The government’s theory that K.W.’s ambivalence, alone,

  warranted the 2013 video’s admission would allow the residual exception to

  “swallow . . . the hearsay rule.” Hammers, 
942 F.3d at 1011
. To admit forensic-

  interview recordings even when victims testify at trial and offer testimony

  consistent with their original allegations would be to risk creating a per se rule

  that such recordings are always admissible in child-sex-abuse cases. We cannot

  condone such a potentially far-reaching result.

        Because the government failed to satisfy Rule 807’s admissibility

  standard for residual-hearsay evidence, the district court’s decision to admit the

  2013 video recording constituted legal error and therefore an abuse of

  discretion per se. Geddes, 71 F.4th at 1214.

        B.    The 2018 Audio Recording

        K.W. was interviewed by the FBI in 2018 during his detention at a

  juvenile correction center. The audio of that interview was recorded and a

  transcript issued. At trial, defense counsel impeached K.W. with statements he

  had made during the 2018 interview. Defense counsel reminded K.W. of his

  2018 statement that he didn’t remember the incident with “Mike in the truck.”

  ROA vol. VI, at 207. K.W. explained that he “did say that, but the reason why

                                          29
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 30



  [he] said that is [he] d[id]n’t like talking about this.” Id. at 207–08. Defense

  counsel recited several more statements from the 2018 interview, which K.W.

  confirmed having made. In going through this line of impeachment questioning,

  defense counsel touched on some inconsistencies between K.W.’s 2018

  interview and his trial testimony. For example, defense counsel noted K.W.’s

  2018 statement that, at the time, he and J.W. were still close friends, compared

  to K.W.’s trial testimony that he “had stopped talking to J.W. after this

  incident” with McFadden. Id. at 209. And there were some other 2018

  statements that K.W. testified he could not recall having made.

        After finishing his cross-examination of K.W., defense counsel moved to

  admit the audio recording of K.W.’s 2018 interview. Defense counsel sought to

  admit the audio recording partly because he believed that the government had

  introduced the 2013 forensic-interview video based on K.W.’s 2018 statements

  that he couldn’t remember the Nebraska trip. So, “[i]n fairness,” defense

  counsel advanced, “the [audio] recording that gave rise to the video should be

  admitted.” Id. at 212. The government replied that “the [2018 audio] recording

  [wa]s not the reason that [the 2013 forensic-interview video] was admitted.” Id.

  The government posited that defense counsel was trying to “impeach [K.W.]

  based on that [2018] transcript, which [defense counsel] had already done and

  c[ould] continue to do if he fe[lt] he ha[d]n’t done it adequately.” Id. at 213.

  But the government maintained that the defense’s impeachment of K.W. did not

  require admitting the 2018 audio recording.

                                          30
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 31



        The district court construed McFadden’s submission of the 2018 audio

  recording as a Rule 807 motion, and so it excluded the recording on the ground

  that defense counsel had failed to give the requisite notice under Rule 807(b).

  Defense counsel explained that he was unable to give notice because he “did

  not plan on asking for the admission of [the audio recording]” based on his

  “assum[ption] that the [2013] video was not going to be admitted.” Id. The

  defense’s position remained that K.W.’s lack of memory made him an

  unavailable witness, so “under the circumstances” the audio recording should

  be admissible. The court dismissed this argument and rebuked the defense for

  failing to “follow the steps that needed to be followed in order to have an 807.”

  Id. at 214. Because defense counsel failed to follow the notice standard under

  Rule 807(b), the court excluded the audio recording.

        Before us, McFadden argues that two rules of evidence foreclose the

  district court’s ruling: Rule 807(b) and Rule 613(b). McFadden also maintains

  his general appeal to fairness advancing that the district court’s evidentiary

  ruling deprived him of his constitutional right to “present a complete defense.”

  Op. Br. at 28 (quoting Crane v. Kentucky, 
476 U.S. 683, 690
 (1986)).

        “[W]e review [the district court’s] legal interpretation of the Federal

  Rules of Evidence de novo and its application of the rules for abuse of

  discretion.” United States v. Armajo, 
38 F.4th 80, 84
 (10th Cir. 2022). Under

  this standard, we discern no error in the district court’s exclusion of the 2018

  audio recording.

              1.    The district court did not abuse its discretion by
                    enforcing Rule 807(b)’s notice requirement.

        McFadden did not move expressly under Rule 807 to admit the 2018

  audio recording, but the district court nevertheless ruled on 807 grounds. On

  appeal, McFadden contends that even “[a]ssuming arguendo that [Rule] 807

  governed [his] request to admit K.W.’s 2018 interview,” the district court erred

  by excluding the recording under the rule’s notice requirement. 6 Op. Br. at 33.

        Rule 807(b) provides that evidence offered under the residual exception

  to hearsay must be introduced with “notice” to the opposing party, either before

  or during trial, unless the court chooses to excuse lack of notice for “good

  cause.” McFadden disputes the district court’s “unyielding adherence” to Rule

  807(b)’s notice requirement and offers four reasons why “good cause” existed

  to excuse his lack of notice: (1) the “2018 recording was created by the

  government”; (2) “K.W. could not remember making the inconsistent

  statements”; (3) the “government asked K.W. rehabilitating questions after

  defense counsel questioned him about the recording”; and (4) the “2018

  recording became especially relevant once the court admitted K.W.’s forensic

  interview.” Op. Br. at 34.

        None of these reasons demonstrate good cause or persuade us that the

  district court clearly erred in finding no good cause for McFadden’s lack of



        6
         The government agrees that the Rule 807 notice issue for the 2018 audio
  recording is preserved.

  notice. The committee notes to Rule 807 advise that the good-cause exception

  might apply when “the proponent may not become aware of the existence of the

  hearsay statement until after the trial begins,” or “the proponent may plan to

  call a witness who without warning becomes unavailable during trial.” Fed. R.

  Evid. 807 advisory committee’s note (2019 Amend.). McFadden certainly knew

  about the existence of the 2018 recording before trial. Indeed, he argued before

  the district court that he did not make a pretrial motion for its admission

  because he “assumed that the [2013] video was not going to be admitted into

  evidence since [K.W.] was going to be able to testify.” ROA vol. VI, at 213.

  That assumption was unreasonable. Caselaw predating McFadden’s trial should

  have alerted the defense that hearsay statements are sometimes admissible even

  when a witness is available to testify at trial, especially in child-sex-abuse

  cases. See, e.g., Harrison, 
296 F.3d at 1007
.

        McFadden further states that the district court was “permitted,” and so

  not required, to waive Rule 807’s notice requirement. Op. Br. at 34. Plenty of

  courts opt to strictly enforce the notice provision. See, e.g., Burgess v.

  Goldstein, 
997 F.3d 541, 561
 (4th Cir. 2021) (reversing the district court’s

  admission of hearsay evidence because the movant did not satisfy the rule’s

  requirement to give notice including the declarant’s name and address); Rotolo

  v. Digital Equip. Corp., 
150 F.3d 223
, 224–25 (2d Cir. 1998) (reasoning a

  videotape that the plaintiff attempted to admit without notice because it was

  publicly available failed Rule 807’s notice requirement and thus was

Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 34



  inadmissible under the rule). We see no reason to intrude on the district court’s

  well-exercised discretion not to excuse McFadden’s failure to give the

  government notice of his intent to introduce the 2018 audio recording, as Rule

  807(b) requires. See Burgess, 
99 F.4th at 1183
 (noting this court’s deference to

  the district court on Rule 807 rulings). And even though McFadden’s motion to

  admit the 2018 recording was not made directly under Rule 807, when the court

  openly treated it as a Rule 807 motion, the defense made no effort to correct the

  record. We cannot fault the court for ruling on Rule 807 notice grounds when

  the defense’s motion might reasonably have been construed under Rule 807 and

  counsel never supplied an alternate rule of evidence to support the recording’s

  admissibility. For all these reasons, the district court’s exclusion of the 2018

  audio recording under Rule 807(b) was proper.

              2.     The arguments presented under Rule 613(b) are waived.

        Rule 613(b) allows for the admission of “[e]xtrinsic evidence of a

  witness’s prior inconsistent statement . . . if the witness is given an opportunity

  to explain or deny the statement and an adverse party is given an opportunity to

  examine the witness about it, or if justice so requires.” McFadden argues that

  this rule entitled him to admit the 2018 audio recording as extrinsic evidence of

  the inconsistency between K.W.’s 2018 statements and his trial testimony. The

  government responds that this argument is unpreserved for appellate review.

  We agree with the government.

        At trial, defense counsel never cited Rule 613(b) as grounds to admit the

  2018 recording. And the colloquy between the court and counsel reveals that

  the court understood McFadden’s motion as one under Rule 807. McFadden

  never corrected this misunderstanding—if, indeed, that’s what it was—and so

  any alternative argument that McFadden might have had under Rule 613(b) was

  not “apparent from the context.” Burke v. Regalado, 
935 F.3d 960, 1014
 (10th

  Cir. 2019); see United States v. Roach, 
896 F.3d 1185, 1191
 (10th Cir. 2018)

  (“To preserve an objection to the exclusion of evidence for appeal, the

  proponent must make an offer of proof at trial, first, describing the evidence

  and what it tends to show and, second, identifying the grounds for admitting the

  evidence.” (cleaned up)). When the district court denied the defense’s motion

  on notice grounds under Rule 807(b), counsel responded that K.W. was

  “unavailable” because he “was unable to remember” certain statements from

  2018. ROA vol. VI, at 213. Citing a witness’s purported unavailability as

  justification for introducing hearsay evidence is not an obvious invocation of

  Rule 613(b)—if anything, this is more suggestive of Rule 804(b). See Fed. R.

  Evid. 804(b) (providing an exception to the rule against hearsay for former

  testimony given by an unavailable witness). And when the district court asked

  defense counsel his purpose for offering the audio recording, counsel responded

  that “[i]n fairness, . . . the recording that gave rise to the 2013 [forensic-

  interview] video should be admitted.” ROA vol. VI, at 212. Nowhere in this



                                           35
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 36



  explanation does defense counsel reference impeachment, which must be the

  purpose of evidence offered under Rule 613(b). 7

        McFadden attempts to connect his “fairness” assertion with Rule 613(b)’s

  provision to allow extrinsic evidence of prior inconsistent statements when

  “justice so requires.” Reply Br. at 14. This connection is too attenuated, and it

  comes far too late. We cannot see how McFadden’s broad appeal to “fairness”

  would have alerted the district court that the defense was making a Rule 613(b)

  motion under the rule’s justice-so-requires prong, without any mention of the

  rule or the defense’s intent to use the audio recording for impeachment

  purposes. See Burke, 
935 F.3d at 1014
; United States v. Cates, 
73 F.4th 795
,

  809 (10th Cir. 2023) (stating that, though “a party need not ‘use any particular

  language . . . to properly preserve an issue for appeal,’” the party must “br[ing]

  [it] to the court’s attention” (quoting Holguin-Hernandez v. United States, 589



        7
          McFadden’s failure to cite impeachment as the purpose for offering the
  2018 audio recording undermines his reliance on United States v. White, where
  we affirmed the district court’s ruling to admit testimony for impeachment
  purposes under Rule 613(b). 
68 F. App’x 870, 874
 (10th Cir. 2003)
  (unpublished). In White, the district court initially denied the government’s
  offered testimony on hearsay grounds, but then reversed that ruling when the
  government explained its intent to use the testimony purely for impeachment
  purposes. 
Id. at 873
. McFadden gave the district court no similar explanation.
  We consider United States v. Mitchell, 
113 F.3d 1528
 (10th Cir. 1997),
  abrogated on other grounds by United States v. Shipp, 
589 F.3d 1084
 (10th Cir.
  2009), inapposite for the same reason. Mitchell is the one instance where this
  court has concluded that a district court’s failure to admit testimony under Rule
  613(b) constituted an abuse of discretion. Id. at 1532. But in Mitchell, both
  parties and the court all understood that the evidentiary rule at issue was Rule
  613(b), which was not the case here. Id.

37 U.S. 169
, 174 (2020))). Because McFadden did not preserve his Rule 613(b)

  arguments at trial and he has not argued for plain-error review on appeal, his

  claim of error under Rule 613(b) necessarily fails. United States v. Martinez, 
92 F.4th 1213
, 1238 n.6 (10th Cir. 2024) (recognizing that an argument “not first

  presented to the district court” hits “the end of the road” when the defendant

  “fail[s] to argue for plain error” on appeal).

               3.    The 2018 audio recording’s exclusion did not violate
                     McFadden’s constitutional right to present a defense.

        McFadden squeezes his fairness argument for all the juice he can: he

  contends next that this argument also raised a constitutional claim that the

  district court’s ruling denied him his due process right to “a meaningful

  opportunity to present a complete defense.” Op. Br. at 28 (quoting Crane, 
476 U.S. at 690
). The government concedes that McFadden’s fairness argument is

  preserved for our review. So we accept that McFadden’s constitutional

  arguments are properly before us. Even so, they are meritless.

        McFadden insists that by excluding the 2018 audio recording the district

  court “violated [his] right to present a defense and confront the witnesses

  against him.” Reply Br. at 22. The Fifth and Sixth Amendments guarantee a

  defendant “the right to present a defense,” which includes “the right to testify,

  present witnesses in his own defense, and cross-examine witnesses against

  him.” United States v. Tapaha, 
891 F.3d 900, 905
 (10th Cir. 2018) (cleaned

  up). This right, though “a keystone of our legal system,” is “not absolute”


                                           37
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 38



  because sometimes it “must bow to accommodate legitimate, competing

  interests in the trial process.” United States v. Rivas-Macias, 
537 F.3d 1271
,

  1277–78 (10th Cir. 2008) (citation omitted). One such competing interest is

  adherence to the Federal Rules of Evidence. United States v. Williams, 
934 F.3d 1122, 1131
 (10th Cir. 2019). “Thus, an evidentiary ruling infringes a

  defendant’s due process rights” to present a defense “only if the district court

  violates the Federal Rules of Evidence.” United States v. Oldbear, 
568 F.3d 814, 820
 (10th Cir. 2009). If the court does violate the rules, we then consider

  whether “the excluded evidence was of such an exculpatory nature that its

  exclusion affected the trial’s outcome.” Williams, 
934 F.3d at 1131
 (quoting

  Tapaha, 
891 F.3d at 905
).

        We have already established that the district court acted within its

  discretion by excluding the 2018 audio recording under Rule 807(b). And even

  if McFadden’s Rule 613(b) arguments were preserved, he contends that the

  recording was admissible under the rule’s “if justice so requires” prong. Fed. R.

  Evid. 613(b). The decision to admit extrinsic evidence in the interest of justice

  is a discretionary determination for the district court to make, and here it was

  never given the opportunity to do so. See 
id.
 advisory committee’s note (2024

  Amend.). The district court did not abuse its discretion by declining to admit

  evidence on grounds that McFadden never brought to its attention. See Cates,

  73 F.4th at 809. The district court is capable but not clairvoyant.

        Our analysis of McFadden’s constitutional claim stops there. See id.;

  United States v. Serrano, 
406 F.3d 1208, 1215
 (10th Cir. 2005) (affirming that

  “the accused does not have an unfettered right to offer [evidence] . . . otherwise

  inadmissible under [the] standard rules” (cleaned up)). McFadden was not

  deprived of his right to present a defense at trial because the district court’s

  exclusion of the 2018 recording was not an abuse of discretion under the

  Federal Rules of Evidence. Williams, 
934 F.3d at 1131
.

        C.     Harmless Error

        Because the district court erred in admitting the 2013 forensic-interview

  video under the residual-hearsay exception, we next consider whether that error

  was harmless. United States v. Chavez, 
976 F.3d 1178, 1204
 (10th Cir. 2020).

  McFadden challenges the video’s admissibility under Rule 807, so we apply the

  nonconstitutional harmless-error standard. 8 See United States v. Blechman, 
657 F.3d 1052, 1067
 (10th Cir. 2011) (“[W]hen a defendant objects to a district

  court’s admission of hearsay based solely on the Federal Rules of Evidence, we

  apply the nonconstitutional harmless error standard.” (cleaned up)). Under this

  standard, an error is harmless “unless a substantial right of a party is affected.”


        8
          McFadden contends that the stricter constitutional harmless-error
  standard applies to his Rule 807 objection. He thinks so because he claims that
  the video’s admission violated his due process right to receive a “fair trial.”
  Op. Br. at 14. But the constitutional harmless-error standard applies to hearsay
  objections when the defendant claims that the admission of the out-of-court
  statement violated his rights under the Confrontation Clause. See United States
  v. Blechman, 
657 F.3d 1052
, 1067 n.15 (10th Cir. 2011). McFadden makes no
  such claim.

  Chavez, 
976 F.3d at 1204
 (alterations omitted) (quoting United States v.

  Charley, 
189 F.3d 1251, 1270
 (10th Cir. 1999)). The government bears the

  burden to prove harmlessness. United States v. Ledford, 
443 F.3d 702, 712

  (10th Cir. 2005).

        Yet here, the government’s response brief fails to assert or even address

  harmlessness as it relates to the 2013 video recording. When the government

  waives harmless error, “this court may in its discretion ‘initiate harmless error

  review in an appropriate case.’” United States v. Samaniego, 
187 F.3d 1222, 1224
 (10th Cir. 1999) (quoting United States v. Torrez-Ortega, 
184 F.3d 1128, 1136
 (10th Cir. 1999)). In deciding whether to proceed with a discretionary

  harmless-error review, we consider “(1) the length and complexity of the

  record; (2) whether the harmlessness of the errors is certain or debatable; and

  (3) whether a reversal would result in protracted, costly, and futile proceedings

  in the district court.” 9 United States v. Holly, 
488 F.3d 1298, 1308
 (10th Cir.

  2007). These factors favor exercising our discretion to reach harmless-error

  review in this case.




        9
           This court has remarked that it’s “unclear what the third factor
  contributes to a court’s decision in determining whether” to “address the issue
  of harmlessness” “sua sponte.” Samaniego, 
187 F.3d at 1225
 n.2. This court has
  declined to apply it before. See Torrez-Ortega, 184 F.3d at 1136–37. We agree
  that the third factor adds little to the discretionary-review calculus for
  harmlessness because “cost and potentially protracted proceedings cannot
  preclude reversal if an error was not harmless.” 
Id.
 So we base our decision on
  the first two factors, only.

        First, the record here is not especially complicated—the trial lasted less

  than a week and involved one defendant and two key witnesses. Compare

  United States v. Doe, 
572 F.3d 1162, 1175
 (10th Cir. 2009) (proceeding to

  harmless-error review because “[t]he record in this case is not lengthy or

  complex” and both defendants’ trials “lasted less than one week”), with Torrez-

  Ortega, 
184 F.3d at 1136
 (declining to exercise discretion to address harmless

  error when the record was “extensive and complex,” because it included

  “twenty-five volumes cover[ing] a two-week, multi-defendant trial”). Plus, all

  the criminal counts in McFadden’s conviction are at issue on appeal, thus we

  are not left with a “difficult task of determining which portions of the

  transcript” are most relevant. Holly, 
488 F.3d at 1308
.

        Second, and most importantly, the question of harmlessness in this case

  is certain. See United States v. Little, 
829 F.3d 1177, 1189
 (10th Cir. 2016)

  (Holmes, J., dissenting) (noting that “the certainty of harmlessness”—the

  second factor—is “[t]he most important” and “can be dispositive under certain

  circumstances”). Exercising our discretion to conduct harmless-error review,

  even when the government has failed to brief the issue, is appropriate “where

  the certainty of the harmlessness is readily apparent.” Holly, 
488 F.3d at 1308
;

  see United States v. Silver, 
954 F.3d 455, 459
 (2d Cir. 2020) (explaining that,

  by opting to address harmless error “without the benefit of briefing,” courts of

  appeal may avoid becoming “locked into interminable cycles of remand or



                                          41
Appellate Case: 23-1089   Document: 010111103175     Date Filed: 08/30/2024    Page: 42



  requests for additional briefing from the parties”). We are convinced that is the

  case here.

        The video recording is harmless partly for the same reason that it is not

  “more probative” under Rule 807(a)(2): K.W.’s video statements from 2013

  mirror his trial testimony. See Torrez-Ortega, 
184 F.3d at 1135
 (considering

  under a harmless-error analysis “whether the testimony was cumulative”

  (citation omitted)); 21 Charles A. Wright & Arthur R. Miller, Fed. Prac. &

  Proc. Evid. § 5035.2 (2d ed.) (June 2024 update) (noting that “improperly

  admitted” evidence “will usually be harmless” “[i]f the . . . evidence was

  simply cumulative of properly admitted evidence”); see also Untied States v.

  Otuonye, 
995 F.3d 1191, 1208
 (10th Cir. 2021) (“Cumulative evidence is

  defined as evidence which goes to prove what has already been established by

  other evidence.” (citation omitted)). Everything that eleven-year-old K.W. says

  on the 2013 video recording was elicited at trial through properly admitted

  testimony: the sleeping arrangements in the semi-truck during the Nebraska

  trip, McFadden’s habit of giving the boys melatonin, McFadden’s previous

  inappropriate touching of K.W. at his Colorado homes, and McFadden’s efforts

  to make his home an appealing place for the boys to come play and sleep over.

        Additionally convincing are that J.W.’s testimony corroborated K.W.’s

  regarding McFadden’s patterns of abuse, that K.W. was old enough to

  understand “the true nature of [his] account[],” Charley, 
189 F.3d at 1271
, and

  that McFadden had an opportunity to thoroughly cross-examine K.W. using

                                         42
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 43



  statements from his 2018 FBI interview and his 2015 state-trial testimony to

  impeach K.W.’s credibility, see United States v. Begay, 
937 F.2d 515
, 524–25

  (10th Cir. 1991) (determining that defendant’s inability to cross-examine child

  victim in a sex-abuse case was not harmless because that limitation “shut off a

  line of vital defense evidence” that, had it been allowed, might have produced

  defendant’s “best evidence of disproving penetration”). The jury also viewed

  several exhibits displaying photos of K.W. when he was eleven-years old,

  which the government introduced with no objection from McFadden. So to the

  extent the video might have “provoke[d] an emotional response in the jury” due

  to K.W.’s young age, the jury already had a mental image of K.W. as a child to

  connect with the allegations in his trial testimony. Otuonye, 
995 F.3d at 1207
.

  Most of all, when the government introduced the 2013 video at trial, the

  defense affirmatively declined the opportunity to request any redactions from

  the thirty-minute-long recording. This, and the above, resolve for us that the

  district court’s error in admitting the 2013 forensic-interview video under Rule

  807 did not “substantial[ly] influence . . . the outcome of the trial.” Blechman,

  
657 F.3d at 1067
.

  II.   Vouching

        McFadden alleges that two witnesses (Detective Prescott and Nurse

  Goebel) vouched for K.W.’s and J.W.’s credibility, which deprived him of a

  fair trial in violation of the Due Process Clause. McFadden concedes that his

  challenge to Goebel’s testimony is unpreserved. So we review his vouching

                                          43
Appellate Case: 23-1089   Document: 010111103175     Date Filed: 08/30/2024   Page: 44



  claim as to Goebel for plain error and his claim as to Detective Prescott for an

  abuse of discretion. United States v. Willis, 
826 F.3d 1265
, 1279 & n.6 (10th

  Cir. 2016).

        This court uses the terms “vouching” and “bolstering” somewhat

  interchangeably when referring to expert testimony or prosecutorial statements

  that “express[] a belief or opinion regarding a witness’s credibility.” United

  States v. Walker, 
85 F.4th 973
, 985 n.9 (10th Cir. 2023); see also United States

  v. Coulter, 
57 F.4th 1168
, 1186–87 (10th Cir. 2023) (noting that we apply “the

  prohibition on bolstering to statements by prosecutors and individuals affiliated

  with the prosecution,” including law-enforcement officers). Vouching might

  involve “blunt comments” affirming the witness’s credibility—as in, “I think

  the witness is honest”—or “comments that place the prestige of the government

  behind a witness.” 75A Am. Jur. 2d Trial § 577 (May 2024 update). At bottom,

  testimony that “usurp[s] the exclusive function of the jury to weigh the

  evidence and determine credibility” should be excluded as improper vouching.

  United States v. Hill, 
749 F.3d 1250, 1260
 (10th Cir. 2014) (quoting United

  States v. Samara, 
643 F.2d 701, 705
 (10th Cir. 1981)).

        A.      Detective Prescott

        McFadden contends that Detective Prescott vouched for the truth of

  K.W.’s sexual-assault allegations. Throughout the trial, McFadden disputed

  K.W.’s credibility because K.W. had initially told his mother on the car ride

  back from Nebraska that McFadden never touched him, and then mere weeks

                                         44
Appellate Case: 23-1089   Document: 010111103175       Date Filed: 08/30/2024   Page: 45



  later K.W. changed his tune during the forensic interview with Detective

  Prescott, after he had met with a child counselor and talked to his mother.

  According to McFadden, this “exposure to outside information” before the

  forensic interview makes K.W.’s interview statements unreliable. Op. Br. at 40.

        McFadden probed Detective Prescott on cross-examination about this

  potential contamination of K.W.’s forensic interview. So on redirect, the

  government asked the detective: “In a forensic interview do you do your best to

  elicit the truth regardless of whether or not the child has been interviewed or

  talked to before you have a chance to talk to them?” ROA vol. VI, at 295.

  Prescott responded, “I do.” 
Id.
 McFadden objected to this testimony on

  relevance grounds, which objection the district court swiftly overruled.

  McFadden reasserts that objection to this court under Federal Rule of Evidence

  Rule 401, and he argues that Detective Prescott’s response of “I do” vouched

  for K.W.’s credibility, depriving him of a fair trial.

        Detective Prescott’s testimony was not vouching. 10 On cross-examination,

  defense counsel attempted to undermine the forensic interview as a reliable


        10
          McFadden’s Rule 401 objection and his corresponding arguments on
  appeal are rooted in his supposition that Detective Prescott’s testimony
  constituted vouching. He alleges that vouching testimony is generally
  inadmissible under Rule 401 because the rule prohibits testimony that
  “encroaches upon the jury’s vital and exclusive function to make credibility
  determinations.” Op. Br. at 39 (quoting Charley, 
189 F.3d at 1267
). Because we
  conclude that Detective Prescott’s testimony was proper, McFadden’s relevancy
  objection fails. Even so, this court’s deference to the district court to make
  relevancy determinations is high, and “[t]he bar for admission under Rule 401
                                                                 (footnote continued)

  process for extracting truthful allegations from children. This line of

  questioning opened the door to the integrity of forensic interviews, generally.

  So naturally, on redirect, the government sought to shore up the forensic-

  interview process as a reliable means for ferreting out truthful statements from

  often-reticent child victims. Detective Prescott’s response spoke generally to

  the truth-seeking function of forensic interviews. Such general statements from

  government agents or law enforcement about the reliability of a particular

  investigatory or fact-finding process is not vouching. See, e.g., United States v.

  Brooks, 
736 F.3d 921
, 934–35 (10th Cir. 2013) (concluding that a government

  agent did not vouch for the witnesses’ credibility by testifying that the proffer

  process was designed “to gauge whether potential cooperators were inclined to

  be truthful”); United States v. Jones, 
468 F.3d 704, 708
 (10th Cir. 2006)

  (determining that testimony stating that, “proffers are used to ‘gauge

  truthfulness’” “do not meet our standard for vouching” because the testimony

  “did not amount to guarantees concerning the veracity of the witnesses”);

  United States v. Magallanez, 
408 F.3d 672, 679
 (10th Cir. 2005) (rejecting

  defendant’s argument that government agents’ “[g]eneral testimony” about

  “how . . . wire records, phone records, and hotel records help investigators to

  determine contact and money transfers” was “improper vouching,” especially


  is very low.” United States v. Wells, 
38 F.4th 1246, 1260
 (10th Cir. 2022)
  (quoting United States v. Jordan, 
485 F.3d 1214, 1218
 (10th Cir. 2007)).
  Nothing in McFadden’s brief convinces us that the district court erred so
  egregiously.
                                          46
Appellate Case: 23-1089   Document: 010111103175     Date Filed: 08/30/2024    Page: 47



  when defendant “opened the door for the government to explain the purpose of

  [those] documents”); United States v. Bowie, 
892 F.2d 1494, 1498
 (10th Cir.

  1990) (clarifying that “[u]se of the ‘truthfulness’ portions” of plea agreements

  “becomes impermissible vouching only when the prosecutors explicitly or

  implicitly indicate that they can monitor and accurately verify the truthfulness

  of the witness’ testimony”). Nothing Detective Prescott said during his

  testimony advocated for the specific truthfulness of K.W.’s forensic-interview

  statements, so his testimony did not cross the line into vouching.

        McFadden’s argument leans heavily on United States v. Jones, a recently

  decided case in which this court determined that a mother’s testimony about her

  daughters’ truthfulness constituted plainly erroneous vouching—an error that

  ultimately led us to vacate the defendant’s conviction and grant a new trial. 
74 F.4th 1065
, 1069–70, 1073 (10th Cir. 2023). But Jones doesn’t support

  McFadden’s argument. In Jones, the defense had not yet attacked the

  daughters’ credibility when the mother testified, so “the door had never been

  opened for testimony vouching for their truthfulness.” 
Id. at 1069
. McFadden

  assailed K.W.’s credibility from the beginning of trial during his opening

  statements by stating that K.W.’s story “gr[ew] over time” between earlier and

  later law-enforcement interviews because “people other than the children” were

  spreading lies about McFadden. These statements invited countervailing

  evidence on the reliability of K.W.’s forensic interview. Jones also differs

  because the mother’s testimony was separately inadmissible under the Federal

                                         47
Appellate Case: 23-1089   Document: 010111103175     Date Filed: 08/30/2024     Page: 48



  Rules of Evidence. 
Id.
 (rejecting the mother’s testimony under Rule 608(a) as

  impermissible character evidence). McFadden identifies no other evidentiary

  rule that would bar Detective Prescott’s testimony. 11 Because Detective

  Prescott’s testimony arose in response to McFadden’s attack on K.W.’s

  credibility and his testimony was otherwise admissible, the district court’s

  decision overruling McFadden’s objection to Detective Prescott’s testimony

  was not an abuse of discretion. See Willis, 
826 F.3d at 1279
 & n.6.

        B.    Nurse Goebel

        Nurse Goebel evaluated J.W. for signs of sexual abuse in March 2013 and

  testified at trial to her findings from that exam. McFadden argues that Goebel

  vouched for J.W.’s credibility by testifying to “her ultimate ‘assessment’ and

  ‘conclusion’” that “there was sexual assault” in J.W.’s case. Op. Br. at 41

  (quoting ROA vol. VI, at 134). McFadden concedes that he did not object to

  this testimony when it was offered, and so we review its admissibility for plain


        11
            McFadden asserts for the first time on appeal that the testimony was
  “unfairly prejudicial” and so “inadmissible under [Rule] 403.” Op. Br. at 39.
  McFadden made no such argument before the district court; regardless, it has
  no merit. For this proposition McFadden looks to Charley, where we
  determined Rule 403 was violated when health counselors testified to their
  conclusions that the child victim was sexually abused because “these statements
  . . . were manifestly outside the counselors’ direct knowledge,” “had minimal
  probative value,” and “were unquestionably prejudicial.” 
189 F.3d at 1270
.
  Detective Prescott’s statements do not resemble the health counselors’ from
  Charley. Detective Prescott’s statements were probative as to the reliability of
  forensic interviews, an issue that McFadden raised, his statements about the
  forensic-interview process were well within the scope of his knowledge, and his
  statements were not unquestionably prejudicial because they did not assert as
  “a statement of fact,” 
id.,
 that K.W. was sexually assaulted.

  error. Walker, 85 F.4th at 983. This requires McFadden to establish (1) an error

  (2) that is plain (3) that affected his substantial rights and (4) that undermined

  the fairness, integrity, and public reputation of the judicial proceeding. United

  States v. Booker, 
63 F.4th 1254, 1258
 (10th Cir. 2023).

           The government concedes the first two prongs of plain error. 12 Even so,

  McFadden hasn’t shown a “reasonable probability” that Goebel’s testimony

  affected his substantial rights, so his claim fails on the third prong of the plain-

  error test. United States v. Benford, 
875 F.3d 1007, 1017
 (10th Cir. 2017).

  Under the third prong, the defendant “bears the burden of establishing” that

  “the error impacted [his] substantial rights.” United States v. Harlow, 
444 F.3d 1255, 1261
 (10th Cir. 2006). “[W]hen reviewing vouching for plain error, we

  weigh the seriousness of the vouching in light of the context of the entire

  proceeding.” 
Id.
 This analysis includes consideration of whether the vouching

  was “slight or confined to a single instance” or “pronounced and persistent.”

  Carter v. Bigelow, 
787 F.3d 1269, 1292
 (10th Cir. 2015) (citation omitted).

           In cases “where the outcome boils down to a believability contest[,] . . .

  testimony vouching for the credibility of the victim is often prejudicial,” but

  even then, prejudice is not a given. Jones, 74 F.4th at 1072 (emphasis added).

  In Jones, the mother’s testimony improperly vouched for her daughters’

  tendency toward truthfulness under Rule 608(a) because, rather than testify to


           12
                We decline to decide whether Goebel’s testimony constituted a plain
  error.

  their character of truthfulness, she testified that they were truthful “on a

  specific occasion.” Id. at 1069. We concluded that this testimony affected the

  defendant’s substantial rights and reversed his conviction on plain-error review.

  Id. at 1072–73. Because the daughters’ credibility was central to the jury’s

  verdict, we reasoned that the effect of the mother’s vouching was “amplified”

  and so created a “reasonable probability” of changing the trial’s outcome. Id. at

  1072. This made Jones different from Charley, where we “held it was harmless

  error to admit the inadmissible testimony because there was overwhelming

  evidence implicating the defendant.” Id. at 1072 n.4.

        Though McFadden’s trial was a “believability contest” between J.W.,

  K.W., and McFadden, Goebel’s testimony lacked the same outsized impact that

  the mother’s testimony had in Jones. The mother in Jones testified about her

  daughters’ specific truthfulness, so both of their allegations were tainted by her

  improper vouching. Id. at 1069. At best, Goebel’s testimony taints J.W.’s

  credibility, only. K.W. testified extensively and compellingly to McFadden’s

  habit of giving K.W. large doses melatonin, McFadden being on top of him in

  the middle of the night with an erect penis, McFadden groping him, and most of

  all, McFadden taking K.W. to Nebraska and anally penetrating him during the

  night in the back of the semi-truck. So it’s not true in this case that “the only

  other evidence cited by the Government . . . is testimony that [the witness]

  vouched for.” Id. at 1072. The conduct described in K.W.’s unvouched-for

  testimony accounted for two of the five criminal counts on which the jury

                                          50
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024    Page: 51



  convicted McFadden and two of the five concurrent life sentences to which the

  district court sentenced him. So even if J.W.’s credibility was tainted, as

  McFadden alleges, McFadden would still have been convicted on two counts

  and sentenced to life imprisonment.

        But we are unconvinced that any vouching in Goebel’s testimony was so

  “pronounced and persistent” as to have affected McFadden’s trial. Carter, 
787 F.3d at 1292
 (citation omitted). In a single comment, Goebel stated her

  impression from J.W.’s exam that he had been sexually assaulted. See, e.g.,

  United States v. Garrett, 
648 F.3d 618
, 624–25 (8th Cir. 2011) (concluding that

  “an isolated comment from one witness in the midst of testimony from twelve

  other witnesses,” though objectionable, did not merit a mistrial). The bulk of

  her testimony covered typical symptoms that she observes in child-sex-abuse

  cases, particularly cases involving anal penetration, and her extensive

  explanations that “[i]n the vast majority of cases” there is “no physical finding

  of anal penetration of the child.” ROA vol. VI, at 145. Goebel never claimed to

  have any expertise in ascertaining the truth from her child patients. And she

  admitted that her exam “isn’t the forensic interview.” Id. at 142. So the jury

  had all the information it needed to weigh the credibility of Goebel’s

  statements. Cf. Magallanez, 
408 F.3d at 682
 (“It is not the role of an appellate

  court to consider the credibility of the witnesses or weigh the conflicting

  evidence, as these matters are within the exclusive province of the jury.”).

  Besides, Goebel’s conclusion was not the lynchpin of the government’s theory

                                          51
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 52



  of guilt. Cf. United States v. Whitted, 
11 F.3d 782, 787
 (8th Cir. 1993)

  (concluding that admission of expert-vouching testimony required reversal in

  part because “[t]he Government heavily relied on [the doctor’s] testimony” in

  prosecuting the case). The prosecution never mentioned Goebel’s impression

  that J.W. had been sexually assaulted during its closing argument, and it did not

  return to the topic when examining her on redirect. See Garrett, 648 F.3d at

  624–25 (considering that “the government did not mention [a witness’s]

  comment during the opening statement or closing argument” in affirming the

  district court’s denial of defendant’s motion for a mistrial).

        McFadden additionally argues that the lack of eyewitnesses in this case

  makes Goebel’s vouching substantially prejudicial. Though it is true that no

  one witnessed the charged assaults, other testimony corroborated J.W.’s general

  account of McFadden’s years-long abuse. McFadden’s boss at the trucking

  company verified that McFadden indeed transported a truck delivery from

  Telluride, CO, to Farmington, NM in December 2010, when J.W. was about

  ten-years old. McFadden’s supervisor at the construction company and landlord

  testified that there were “normally” “three or four” young boys “around

  [McFadden],” even though there was no business reason for young boys to

  accompany McFadden on work trips. ROA vol. VI, at 461. And it’s not as

  though McFadden was accused of one, isolated incident of assault to which

  there were no eyewitnesses. See United States v. Velarde, 
214 F.3d 1204, 1212

  (10th Cir. 2000) (concluding that expert testimony vouched for the victim’s

                                          52
Appellate Case: 23-1089   Document: 010111103175       Date Filed: 08/30/2024   Page: 53



  credibility and affected defendant’s trial in part because “in this case, a young

  girl testified to a single instance of alleged sexual abuse” with “relatively little

  other evidence” (emphasis added)). J.W. testified to an intimate relationship

  with McFadden that formed throughout his childhood, which then gave

  McFadden the opportunity to assault J.W. on the out-of-state truck trips. J.W.’s

  mother corroborated this dynamic. She testified that McFadden “took the lead”

  in taking care of J.W., that she struggled with a methamphetamine addiction

  during J.W.’s youth, and that she knew J.W. slept in McFadden’s bedroom

  when he stayed at McFadden’s house. She also confirmed that J.W. frequently

  accompanied McFadden on semi-truck trips, sometimes out of state, and that

  due to her drug addiction there were times when she “didn’t even realize that

  [J.W.] was gone.” ROA vol. VI, at 448. So even though there were no

  eyewitnesses to McFadden’s sexual abuse, multiple witnesses substantiated

  J.W.’s testimony about McFadden’s pattern of traveling across state lines with

  young boys and his unfettered access to J.W. for large portions of his

  childhood. This evidence establishes that McFadden had “the opportunity to

  commit the crimes.” Charley, 
189 F.3d at 1271
 (considering favorably under a

  harmless-error analysis that defendant “was on supervised release at the time of

  the events in question” and that the victims were home alone).

        Based on the evidence in this case, McFadden has not carried his burden

  to show “a reasonable probability that but for” Goebel’s limited testimony



                                           53
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 54



  about J.W.’s report of abuse, “he would not have been convicted.” Hill, 
749 F.3d at 1266
.

  III.   Cumulative Error

         “In a cumulative-error analysis, we aggregate all the separate

  nonreversible trial errors to assess whether, together, they created reversible

  error.” United States v. Guinn, 
89 F.4th 838, 850
 (10th Cir. 2023). When

  preserved and unpreserved errors occurred at trial, we consider whether the

  preserved errors—even if, together, they are harmless—plus the unpreserved

  errors, collectively create prejudice that demands reversal. United States v.

  Caraway, 
534 F.3d 1290, 1302
 (10th Cir. 2008).

         McFadden argues that a combination of preserved and unpreserved errors

  were committed during his trial. He asserts that the admission of the 2013

  forensic-interview video recording, the exclusion of the 2018 audio recording,

  and the vouching testimony from Detective Prescott and Nurse Goebel

  cumulatively “misled the jury about the quantity and quality of evidence

  against Mr. McFadden,” creating “collective prejudice” that now requires

  reversal and a new trial. Op. Br. at 46. Among these, we have recognized one

  nonreversible error: the admission of the 2013 video recording. But McFadden

  must demonstrate “at least two errors before we may find cumulative error.”

  Willis, 
826 F.3d at 1280
. Because we lack multiple errors to aggregate in the

  cumulative-error analysis, McFadden’s argument fails.

  IV.   Undue-Influence Enhancement

        The district court applied a two-level undue-influence enhancement to

  McFadden’s total offense level under U.S.S.G. § 2G1.3(b)(2)(B). McFadden

  objected to the enhancement’s application during sentencing and challenges it

  again on appeal. When we evaluate the district court’s calculation of a

  Guidelines sentence, we review the court’s factual findings for clear error and

  its legal conclusions de novo. United States v. Jackson, 
82 F.4th 943
, 949 (10th

  Cir. 2023). In this case, the district court properly applied the § 2G1.3(b)(2)(B)

  enhancement.

        The undue-influence enhancement authorizes two levels for defendants

  who “unduly influenced a minor to engage in prohibited sexual conduct.”

  § 2G1.3(b)(2)(B). The Guidelines Commentary explains,

        In determining whether subsection (b)(2)(B) applies, the court
        should closely consider the facts of the case to determine whether a
        participant’s influence over the minor compromised the
        voluntariness of the minor’s behavior. The voluntariness of the
        minor’s behavior may be compromised without prohibited sexual
        conduct occurring.

  § 2G1.3(b)(2)(B), cmt. 3(B). If the defendant is at least ten years older than the

  minor, then the Commentary implements a “rebuttable presumption that

  subsection (b)(2)(B) applies.” Id. The rebuttable presumption “shifts the burden

  of producing evidence to rebut the presumption to [the defendant],” though the

  government always bears the ultimate burden of proving that a sentencing




                                          55
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 56



  enhancement applies. United States v. Castellon, 
213 F. App’x 732, 737
 (10th

  Cir. 2007) (unpublished).

        At the sentencing hearing, the district court found that McFadden

  submitted no evidence to rebut the presumption. McFadden’s “sole argument,”

  the court noted, was that K.W. and J.W. “were either asleep or so sick” when

  McFadden abused them and therefore that “there could be no undue influence

  to get them to engage in sexual activity with him.” ROA vol. VI, at 546. But

  the court discerned that by instilling himself as a trusted figure in the boys’

  lives, McFadden “induced” both boys to “sleep in the bed with him and go on

  overnight trips,” where he was then “able to rape them.” 
Id.
 Because McFadden

  failed to rebut the presumption, the district court overruled his objection and

  applied the enhancement.

        McFadden concedes that the rebuttable presumption applies because he is

  over ten years older than J.W. and K.W. McFadden argues instead that he

  couldn’t have exercised undue influence over the boys because “there is no

  allegation that J.W. or K.W. ‘voluntarily’ or ‘willingly’ engaged with [him]

  during their alleged sexual assaults.” Op Br. at 50 (quoting Castellon, 
213 F. App’x at 736
).

        This argument interprets § 2G1.3(b)(2)(B) too narrowly. The

  enhancement is not limited to circumstances where a victim voluntarily

  engaged in sex—it also “reaches ‘manipulating’ and ‘preying upon’ a

  vulnerable victim” in order to procure sex. United States v. Reid, 
751 F.3d 763
,

                                          56
Appellate Case: 23-1089   Document: 010111103175       Date Filed: 08/30/2024    Page: 57



  768 (6th Cir. 2014); see, e.g., Castellon, 
213 F. App’x at 738
 (affirming the

  district court’s application of § 2G1.3(b)(2)(B) partly because the court had

  correctly considered “the fact that [defendant] picked [victim] up in the middle

  of the night for sexual liaisons at hotels he paid for, . . . drove her all the way

  from Albuquerque to Mexico for further such liaisons, all while she had no

  money and no identification”). Even if the boys never consented to the specific

  sex acts that McFadden performed, his efforts to groom them for sex are

  enough for the enhancement to apply. See, e.g., United States v. Kempter, 
29 F.4th 960, 966
 (8th Cir. 2022) (applying the § 2G1.3(b)(2)(B) enhancement

  “based on a manipulative adult’s building a relationship with a minor for the

  purpose of eventual sexual activity” (cleaned up)); United States v. Brooks, 
610 F.3d 1186, 1199
 (9th Cir. 2010) (affirming the § 2G1.3(b)(2)(B) enhancement

  on appeal because victims “had no money, no job and, as runaways, nowhere to

  live” when defendants enticed them into prostitution).

        Even setting the presumption aside, ample evidence in the record

  supports the district court’s conclusion that McFadden leveraged his position in

  J.W.’s and K.W.’s lives to lure them into scenarios that facilitated his abuse.

  J.W. testified that he saw McFadden as a father-figure. J.W. explained how his

  mother struggled to provide for him and how McFadden stepped in to give J.W.

  clothing, food, housing, toys, and a fun environment away from his mother’s

  abusive boyfriend. K.W. similarly testified that he loved going to McFadden’s

  house to play with J.W. and the other children. K.W. said that his family didn’t

                                           57
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024    Page: 58



  have much money, and so he got clothes, toys, and necessities from McFadden.

  After cultivating a close relationship with these two similarly disadvantaged

  boys, McFadden arranged for them to sleep in his bed with him. McFadden then

  took both boys out of state on long trucking routes, where the only true place to

  sleep was a shared mattress in the semi-truck’s sleeper cab. Once McFadden

  got the boys in his bed and in his truck, he sexually assaulted them. This

  evidence justifies the district court’s application of the § 2G1.3(b)(2)(B)

  enhancement.

        We affirm McFadden’s sentence as imposed by the district court.

                                   CONCLUSION

        Affirmed.

  No. 23-1089, United States v. McFadden
  FEDERICO, Circuit Judge, dissenting in part

        The majority rightly concludes that the admission into evidence of the

  2013 video recording of a forensic interview with a then eleven-year-old K.W.

  was error. But I do not agree this error was harmless. Rather, I would accept

  the government’s concession that the error was not harmless and thus decline

  to sua sponte do the government’s work for them (which they are not even

  arguing should be done). The exercise of this court’s discretion to engage in a

  sua sponte harmless error review is not warranted when, as here, the

  harmlessness is easily debatable. Nonetheless, engaging in a harmless error

  review, I reach a different conclusion than the majority.

        Because the admission of the 2013 video affected McFadden’s

  substantial rights, I would set aside the convictions and sentence for Counts 1

  and 2 (the two charges naming K.W. as the victim), vacate the judgment on

  these counts, and remand for further proceedings.1

                                          I

        Not every erroneous admission of evidence merits relief to a defendant.

  An error is harmless if it “does not affect substantial rights.” Fed. R. Crim. P.

  52(a). The government bears the burden to prove harmlessness. United States




        1 I otherwise agree with the majority on the remainder of the issues

  before us in this appeal.
Appellate Case: 23-1089   Document: 010111103175    Date Filed: 08/30/2024   Page: 60



  v. Ledford, 
443 F.3d 702, 712
 (10th Cir. 2005). By assigning a burden to a party,

  the law thus requires that party to either meet their burden or suffer defeat on

  that matter before the court. Here, the government surrendered this point,

  declined to argue harmlessness, and conceded the video was prejudicial. Aple.

  Br. at 25–40; Oral Arg. at 19:00 – 19:40.

        Pause to reflect on this point. On appeal, the government’s duty is to

  defend the convictions it secures at trial after the expenditure of significant

  time, labor, and resources.2 The government is very capable of doing this and,

  rightfully, is usually not timid about arguing all potential legal paths to

  affirmance.3 But here, the government concluded the video was so prejudicial

  that if this court were to find that its admission into evidence was erroneous

  (as we have now done), it would not be a plausible argument or strategy to fall

  back on harmless error.




        2 Consider the government’s determination and effort to admit the 2013

  video into evidence. To meet its burden of admissibility under the Rule 807
  residual hearsay rule, the government provided pretrial notice to the
  defendant and then presented the evidence and its argument to the district
  court in a pretrial evidentiary hearing. At trial, it had a transcript produced
  and ready to provide to the jury when it moved the video into evidence. Upon
  admission, the jury was given the transcript as an aid to assist in
  understanding what was said during the video, which the jury watched in open
  court.

        3 In fact, the government argued harmless error regarding two of the

  issues raised in this appeal – the 2018 audio recording and the alleged
  vouching testimony of Nurse Goebel. Aple. Br. at 47, 64.
                                         2
Appellate Case: 23-1089   Document: 010111103175    Date Filed: 08/30/2024   Page: 61



        Even when the government does not argue an error was harmless under

  Rule 52(a), we retain the discretion to independently assess harmlessness “in

  an appropriate case.”4 United States v. Samaniego, 
187 F.3d 1222, 1224
 (10th

  Cir. 1999) (quoting United States v. Torrez-Ortega, 
184 F.3d 1128, 1136
 (10th

  Cir. 1999). But determining what constitutes “an appropriate case” is not a

  straightforward task.

        The Rule 52 harmless error rule was adopted in 1944 as “a restatement

  of existing law.” Fed. R. Crim. P. 52 1944 Advisory Committee Notes. However,

  it was not until 1992 that we affirmatively stated that our court may exercise

  its discretion to initiate a harmless error review when the government did not




        4 Rule 52(b) states, “a plain error that affects substantial rights may be

  considered even though it was not brought to the court’s attention.” Fed. R.
  Crim. P. 52(b). It is the flip side of the coin to the Rule 52(a) harmless error
  standard. Plain error is argued by defendants seeking appellate relief when
  they have not adequately preserved their objections before the district court.
  However, unlike harmless error, our cases hold firm that “it is the obligation
  of the [defendant] to identify, and argue for” plain error, and “[t]he failure to
  argue for plain error and its application on appeal . . . surely marks the end of
  the road for an argument for reversal not first presented to the district court.”
  United States v. McBride, 
94 F.4th 1036, 1044
 (10th Cir. 2024) (quoting
  Richison v. Ernest Grp., Inc., 
634 F.3d 1123, 1131
 (10th Cir. 2011)). So, when
  it comes to applying Rule 52, what is good for the government goose is
  apparently not also good for the defendant gander.

  make that argument independently.5 United States v. Langston, 
970 F.2d 692
,

  704 n.9 (10th Cir. 1992).

        In Torrez-Ortega, we adopted the factors established by the Seventh

  Circuit in United States v. Giovannetti, 
928 F.2d 225, 227
 (7th Cir. 1991), as

  relevant for deciding whether to exercise our discretion to conduct an

  independent harmless error analysis in the absence of government

  presentation on the inquiry. 
184 F.3d at 1136
. The three factors are:

     (1) the length and complexity of the record,

     (2) whether the harmlessness of the error or errors found is certain or

        debatable, and

     (3) whether a reversal will result in protracted, costly, and ultimately futile

        proceedings in the district court.

  
Id.
 Although we purposefully did not decide in Torrez-Ortega whether the three

  Giovannetti factors are exhaustive, we have effectively treated them as such in

  subsequent cases. See, e.g., Samaniego, 187 F.3d at 1224–25; United States v.

  Holly, 
488 F.3d 1298, 1308
 (10th Cir. 2007); United States v. Doe, 
572 F.3d 1162, 1175
 (10th Cir. 2009); United States v. Spence, 
721 F.3d 1224
, 1230 n.6


        5 Our cases that established and discussed this discretionary authority

  do not mention the Federal Rules of Appellate Procedure mandate that an
  appellee’s brief (which is typically the government in criminal appeals) “must
  contain . . . the argument, which must contain . . . appellant’s contentions and
  the reasons for them” and “for each issue, a concise statement of the applicable
  standard of review.” Fed. R. App. P. 28(a)(8), (b) (emphases added).

  (10th Cir. 2013); United States v. Little, 
829 F.3d 1177, 1189
 (10th Cir. 2016)

  (Holmes, J., dissenting).

        Generally, the three enumerated factors are problematic in their

  application. Ditching the third factor and applying only the first two, the

  majority concludes that we should engage in a harmless error analysis without

  the benefit of the parties’ arguments about it. I respectfully disagree.

        The first factor – length and complexity of the record – is phrased in the

  conjunctive, recognizing that these are not necessarily harmonious terms.

  Length does not necessarily convey complexity, nor does complexity mean a

  record is of substantial length. Nevertheless, our cases usually apply this factor

  based on the number of pages in the record or the number of days of the trial.

  Again, it is not obvious why those metrics – page numbers and trial days –

  matter at all as to whether we can or should conduct our own harmless error

  inquiry.

        Rather, the better question is whether the record is complete and

  adequate for us to do a harmless error review because it contains all that we

  need to review to do it, not whether it is hard or labor intensive because the

  record is lengthy and documents that a lot happened at the trial court.

  Samaniego, 
187 F.3d at 1225
 (noting the “record itself is abysmally inadequate

  for a harmless-error review”). We have the video, all admitted exhibits, and the

  entire trial transcript before us in the record on appeal. In applying this factor,

                                          5
Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 64



  I agree with the majority that we have all we need in this record for a harmless

  error review, so this factor weighs in favor of us exercising our discretion.

        The second factor – whether the error’s harmlessness is certain or

  debatable – has been deemed “the most important” factor and was correctly

  emphasized as so by the majority. Little, 
829 F.3d at 1189
 (Holmes, J.,

  dissenting). But certainty seems not only elusive in this context but non-

  existent. How can we conclude the harmlessness of the error is certain when

  the government, represented by lawyers at trial and on appeal who have the

  professional obligation and wherewithal to save convictions from reversal in

  the face of erroneous trial rulings, not only failed to argue harmless error but

  conceded it should not apply? To answer my own question – we cannot and,

  indeed, should not.

        Reaching this conclusion is not ceding our own judicial obligations to the

  government. Rather, it recognizes that “harmlessness could be vigorously

  debated here.” 
Id.
 That debate should include the government raising

  harmlessness and the defendant being afforded the opportunity to respond to

  the arguments first made by the government. Indeed, as I will elaborate in the

  next section, a vigorous debate on harmlessness is warranted and, in my view,

  leads to a conclusion different from that reached by the majority.

        Finally, the majority is correct that the third factor – whether reversal

  would result in protracted, costly, and futile proceedings in district court – adds

                                          6
Appellate Case: 23-1089   Document: 010111103175    Date Filed: 08/30/2024   Page: 65



  little to the discretionary review calculus. See also Mollett v. Mullin, 
348 F.3d 902, 920
 (10th Cir. 2003) (noting that “confusion about what the third factor

  contributes to the analysis has caused this and other courts to merely reference

  [the third factor] but not apply it” (quoting Samaniego, 
187 F.3d at 1225
 n. 2)).

  Rather than just casually abandoning this factor, we should permanently drop

  it from our case law altogether.

        In sum, only one of the three Torrez-Ortega factors weigh in favor of a

  sua sponte harmless error review. Because the question of harmlessness is far

  from certain, we should not exercise our discretion to engage in this inquiry on

  our own behalf and without the benefit of party presentation.

        Although we should not conduct a sua sponte harmless error review, I

  nevertheless do so to track the majority opinion. I conclude that the admission

  of the video was not harmless.

        The error here was a violation of a rule of evidence, so it was not a

  constitutional error. For non-constitutional errors, the government must prove

  the error did not have a “substantial and injurious effect or influence in

  determining the jury’s verdict.” Kotteakos v. United States, 
328 U.S. 750, 776

  (1946). Specifically:

        [I]f one cannot say, with fair assurance, after pondering all that
        happened without stripping the erroneous action from the
        whole, that the judgment was not substantially swayed by the
        error, it is impossible to conclude that substantial rights were
        not affected. The inquiry cannot be merely whether there was
        enough to support the result, apart from the phase affected by
        the error. It is rather, even so, whether the error itself had
        substantial influence. If so, or if one is left in grave doubt, the
        conviction cannot stand.

  
Id. at 765
. To conduct this review, we “review[ ] the record as a whole de

  novo to evaluate whether the error [was] harmless, examining the context,

  timing, and use of the erroneously admitted evidence at trial and how it

  compares to properly admitted evidence.” United States v. Blechman, 
657 F.3d 1052
, 1067–68 (10th Cir. 2011) (quoting United States v. Hanzlicek,

  
187 F.3d 1228, 1237
 (10th Cir. 1999)) (alterations in original).

        In other words, we must scrutinize the entire trial record, years after

  the trial occurred in another time and place, to determine whether the jury’s

  verdicts on Counts 1 and 2 were influenced by viewing a video they should

  not have seen. And, to again beat the drum of the preceding section, for us

  to conclude that this factor weighs in the government's favor, we must be

  certain that the video did not substantially sway the jury. With this

  framework in mind, I explain why I reach the opposite conclusion of the

  majority – that the erroneous admission of the video was harmful, not

  harmless.

                                         B

        K.W. is the victim in Counts 1 and 2 of the indictment. Both counts

  arise from a trucking trip that began in Colorado, stopped in Idaho, and

  ended in Nebraska, when the defendant was arrested on January 2, 2013,

  at a Love’s truck stop. K.W., who was eleven years old at the time of the

  trip, was accompanied by his two brothers, one older and one younger. J.W.,

  the victim in Counts 3, 4, and 5, was not on the trip. During the trip, the

  defendant sexually assaulted K.W., who disclosed the assault to Detective

  Prescott during a video-recorded forensic interview on January 16, 2013,

  two weeks after the defendant’s arrest.

        The trial occurred nine years later, in November 2022.6 K.W. was

  twenty years old when he testified at trial. K.W. testified about the sexual

  assault that occurred during the trip as follows:

        GOVERNMENT: Did Mr. McFadden do anything on that trip
        specifically that made you uncomfortable?

        K.W.: Yes.

        GOVERNMENT: What did he do?

        K.W.: He tried to stick his thing in me.

        GOVERNMENT: By stick his thing in you, did Mr. McFadden put
        his penis in your butt?

        6 As the majority explains, McFadden was first tried and convicted in

  state court. The federal charges were not filed until after his state conviction
  and sentence were overturned on appeal.

        K.W.: He tried to, yes.

        GOVERNMENT: What do you mean he tried to?

        K.W.: It just wouldn’t go in necessarily, so he just tried to, and then
        after a while he just gave up.

                                        

        GOVERNMENT: When you say he tried to put his penis in you,
        did he put his penis into your butt?

        K.W.: Yes.

        GOVERNMENT: How did that feel?

        K.W.: It hurt, because I was little at the time. It hurt a lot. Again,
        I don’t remember a lot. Again, I’ve tried to suppress most of these
        memories, just try to fade them out.

  R.V at 182–83. At the end of K.W.’s direct examination, the government moved

  to admit his 2013 forensic interview with Detective Prescott under Federal

  Rule of Evidence 807.

        The district court asked: “In light of the fact that the witness testified

  that he did remember the truck assault, what is the purpose of the video?” Id.

  at 193. The government asserted the video was the “most probative evidence

  on that point” because “K.W., while he did discuss the events in question, did

  so reluctantly and often after my prompting and after I used the words that he

  seemingly cannot.” Id. The district court then admitted the video, finding that




                                          10
Appellate Case: 23-1089   Document: 010111103175   Date Filed: 08/30/2024   Page: 69



  K.W. was “reluctant” and “only answered with prompting and he was equivocal

  about the penetration.” Id. at 195.

        Context and a description of the video are also important to our

  harmless error review. The video (Government Exhibit 6) is 32 minutes and

  40 seconds. The camera is set in a corner, so the viewpoint of the recording

  is looking down upon a room, which has a small blue sofa, a blue chair, and

  a white dry-erase board between the sofa and chair. Here is an image from

  the video (K.W. is blocked in this image by Detective Prescott while he

  closes the door):




        K.W. walked into the room and sat on the blue sofa wrapped in a

  blanket. He portends the nervous energy of a child. His first comments to


                                        11
Appellate Case: 23-1089   Document: 010111103175   Date Filed: 08/30/2024   Page: 70



  Detective Prescott were, “There is a computer in that other room,” as he

  pointed towards the door, adding, “I want to go play on it.” Govt. Ex. 6 00:00

  – 00:13. During the interview, K.W. acts his age: he throws himself around

  the couch and floor, lies on the couch, and mumbles a lot of his words.

        The majority concludes that the video’s admission into evidence is

  harmless for the same reason it is not more probative under Rule 807(a)(2)

  because, it says, K.W.’s video statements from 2013 mirror his trial

  testimony. I respectfully disagree.

        First, his testimony at trial and his statements in the video are not

  mirrors of each other. The substance is similar, but they are not the same.

  For example, in both his testimony and the video he said the words to

  describe a “sexual act,” an element of Count 1 and defined for the jury in

  the court’s instructions. R.I at 908. But although some of the words and

  language used in both are the same or similar, they are not “mirrored”

  because these types of evidence are qualitatively different.

        Evidence is not just the words or text later put to paper on a

  transcript. Trials are live events, where jurors watch how witnesses testify

  as much as they listen to their words. The consumption of information

  through live testimony is qualitatively different than watching a video of




                                        12
Appellate Case: 23-1089   Document: 010111103175    Date Filed: 08/30/2024   Page: 71



  an interview that was conducted in a controlled environment.7 The eleven-

  year-old K.W. talking to a detective in a comfortable room, while draped in

  a blanket, and lying on a small blue sofa, is not the same as a twenty-year-

  old K.W. testifying in person before the jury, eight years later, recounting

  what happened in the past.

        This is not to say that the differences in the types of evidence make

  the video “more probative” than his live testimony under the residual

  hearsay rule, which requires a court to weigh the proffered evidence against

  “any other evidence that the proponent can obtain through reasonable

  efforts.” Fed. R. Evid. 807(a)(2). In balancing between the two, the majority

  is correct that live testimony was superior and more probative evidence.8




        7 This is also why I do not hang my harmless error hat on a cumulative

  evidence analysis. United States v. Otuonye, 
995 F.3d 1191, 1208
 (10th Cir.
  2021).

        8 The majority notes there is one key difference between this case and

  United States v. Burgess, 
99 F.4th 1175, 1182
 (10th Cir. 2024), in which this
  court affirmed the admission of a forensic interview video of a child victim
  under the residual hearsay rule. That difference being that the child’s
  testimony in Burgess diverged from the original accusation made during the
  video-recorded forensic interview.

        I emphasize another key difference – the child in Burgess was seven
  years old when she was abused, seven when she sat for a forensic interview,
  and nine when she testified at trial. In other words, she remained a young child
  throughout the entirety of the case, from allegation through trial. Not so here,
  where K.W. grew from a young boy of eleven in 2013 when the video was
  recorded to a young man of twenty when he testified at trial.

Appellate Case: 23-1089   Document: 010111103175      Date Filed: 08/30/2024   Page: 72



  United States v. Harrison, 
296 F.3d 994, 1007
 (10th Cir. 2002); United

  States v. W.B., 
452 F.3d 1002
, 1005–06 (8th Cir. 2006).

        Second, the video is not harmless because it improperly bolstered

  K.W.’s credibility. See Fed. R. Evid. 608(a)(2); United States v. Bowie, 
892 F.2d 1494, 1499
 (10th Cir. 1990). The jurors heard K.W.’s tepid testimony

  about the abuse. Although other facts and circumstantial evidence

  generally corroborated K.W.’s testimony, his testimony was the only

  evidence regarding the element that a “sexual act” occurred. As the majority

  states, K.W.’s credibility shoulders the government’s case because no one

  else testified that they bore witness to the alleged assault.9 That is why the

  32-minute video, which had the purpose and effect only to improperly

  bolster K.W.’s credibility, was not harmless. The jurors10 heard his

  testimony and then watched him on video, in a controlled setting, give

  similar answers to similar questions posed by a trained detective.




        9 The jurors were instructed that each count on the indictment “involve

  separate additional factual determinations that you must make. . . . Each crime
  or offense as charged and the evidence applicable thereto should be considered
  separately as to each count.” R.I at 907.

        10 The fact that this was a jury trial is key to the bolstering analysis. Had

  this been a bench trial, witness bolstering would not have the same effect. See,
  e.g., United States v. W.B., 
452 F.3d 1002, 1006
 (8th Cir. 2006) (“The district
  court conducted a bench trial and in such a situation, we find little prejudice
  in the admission of cumulative evidence or testimony which improperly
  bolsters a prior witness.”).
                                         14
Appellate Case: 23-1089   Document: 010111103175   Date Filed: 08/30/2024   Page: 73



        The majority also concludes that any harm done by the jurors

  watching the video and seeing K.W. as a child was offset by the fact that

  the government also admitted into evidence photographs depicting K.W. at

  eleven years old. They conclude that this mitigated the “emotional response

  in the jury,” having already seen him as a child in the photographs. United

  States v. Otuonye, 
995 F.3d 1191, 1207
 (10th Cir. 2021). But again, seeing

  photographs of a child compared to watching that child for 32-plus minutes

  on video is not the same. People are more than their images. When it comes

  to how jurors will consume and absorb evidence, other personal

  characteristics also matter, such as: voice, mannerisms, temperament,

  conduct, inflection, etc. This is one reason why our judicial system prefers

  jurors to observe live testimony of witnesses. Garcia-Martinez v. City &

  Cnty of Denver, 
392 F.3d 1187, 1191
 (10th Cir. 2004).

        Finally, the majority concludes that “most of all” McFadden’s failure

  to request redactions from the video renders its admission harmless. The

  defense objected to the admission of the video, so I do not see how the failure

  to request redactions to the video after it was admitted into evidence then,

  ipso facto, converts this error to being harmless.

        I simply cannot conclude that the erroneous admission of the video

  did not have a substantial effect or influence on the jury’s verdicts for

  Counts 1 and 2. Kotteakos, 
328 U.S. at 765
. Because I both disagree with

                                        15
Appellate Case: 23-1089   Document: 010111103175   Date Filed: 08/30/2024   Page: 74



  the decision to conduct a sua sponte harmless error analysis and conclude

  that McFadden’s substantial rights were violated, I respectfully dissent from

  that part of the majority opinion.
