¶1 Russell Marks (“Marks”), federal prisoner # 06550-045, appeals the district court’s dismissal of his 28 U.S.C. § 2241 petition in which he challenged his convictions and sentences for conspiracy to distribute cocaine and conspiracy to launder monetary instruments. Marks argues that his guilty plea was involuntary because the trial court did not advise him that he faced a mandatory sentence of life imprisonment. He contends that he should be allowed to proceed under 28 U.S.C. § 2241 because “he has not had an unobstructed shot at getting his conviction or sentence vacated.” Marks cites to Dretke v. Haley, 541 U.S. 386, 124 S.Ct. 1847, 158 L.Ed.2d 659 (2004) and United States v. White, 371 F.Supp.2d 378 (W.D.N.Y.2005) in support of his argument.
¶2 Marks has not shown that his claim meets the requirements of 28 U.S.C. § 2255’s “savings clause.” He has not shown that his claim is based on a retroactively applicable Supreme Court decision which establishes that he may have been convicted of a nonexistent offense and that such claim was foreclosed by circuit law at the time when the claim should have been raised in his trial, appeal, or first 28 U.S.C. § 2255 motion. See Reyes-Requena v. United States, 243 F.3d 893, 904 (5th Cir. 2001). Therefore, the district court’s dismissal of Marks’s 28 U.S.C. § 2241 petition is AFFIRMED.
