¶1JUDGMENT
¶2This cause was considered on the record from the United States District Court for the District of Columbia, and was briefed and argued by counsel. It is
¶3Ordered and Adjudged that the judgment of the District Court be affirmed.
¶4Appellant was convicted on counts of unlawful possession of a firearm and ammunition by a felon, 18 U.S.C. § 922(g)(1), assault with a dangerous weapon, D.C. Code § 22-502, possession of a firearm *114during the commission of a crime of violence or dangerous offense, D.C. Code § 22-3204(b), and threatening to injure or physically damage. D.C. Code § 22-2307. He asserts two grounds for appeal.
¶5First, appellant argues that the District Court erred by giving a coercive supplemental jury instruction after the jury requested the dismissal of a disruptive juror. This objection appears to have been waived. Defense counsel objected to the giving of any instruction at trial; however, appellant’s argument on appeal challenges the content of the disputed instruction, not the giving of an instruction. Any challenge to the content of the supplemental instruction was clearly abandoned at trial, because defense counsel expressly disclaimed any disagreement with the District Court’s chosen language. See Trial Tr. at 505 (Feb. 25, 2002). Such acquiescence waives the objection. See United States v. Sutton, 801 F.2d 1346, 1367 (D.C.Cir.1986).
¶6Even if the objection was not clearly waived, the alleged error was not properly preserved and thus we review only for plain error. See United States v. Breedlove, 204 F.3d 267, 270 (D.C.Cir.2000). Deviation in the instruction from the language we approved in United States v. Thomas, 449 F.2d 1177, 1187 (D.C.Cir.1971), would be error, regardless of whether or not the jury had actually reached a deadlock. Although it is debatable whether the District Court’s supplemental instruction materially failed to conform to the Thomaslanguage, we will assume, arguendo, that the instruction was error. Nevertheless, appellant fails to meet his burden under Johnson v. United States, 520 U.S. 461, 466-70, 117 S.Ct. 1544, 137 L.Ed.2d 718 (1997), and United States v. Olano, 507 U.S. 725, 732-37, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993), of demonstrating an actual prejudicial effect on the verdict. On this record, we find no plain error.
¶7Second, appellant seeks a new trial on the ground that the prosecutor expressed a personal belief as to appellant’s guilt during rebuttal argument. See Trial Tr. at 446 (Feb. 21, 2002). This argument is without merit. The prosecutor’s statement on summation was not improper and did not prejudice appellant. See, e.g., United States v. North, 910 F.2d 843, 894-98 (D.C.Cir.1990). Furthermore, when defense counsel objected to the summation, the District Court admonished the prosecutor who then turned to a different line of argument. See Trial Tr. at 446 (Feb. 21, 2002). Thus, if there was even a hint of error, the District Court quickly quashed it.
¶8Pursuant to D.C. Circuit Rule 36, this disposition will not be published. The Clerk is directed to withhold issuance of the mandate herein until seven days after resolution of any timely petition for rehearing or rehearing en banc. See Fed. R.App. P. 41(b); D.C.Cir. Rule 41.
