Appealing the judgment in a criminal case, Juan Manuel Muñoz raises arguments that he concedes are foreclosed. See United States v. Rawls, 85 F.3d 240, 242 (5th Cir. 1996) (rejecting Commerce Clause-based challenge to 18 U.S.C. § 922(g)(1)). Accordingly, the Government’s motion for summary affirmance is GRANTED, its alternative motion for an extension of time to file a brief is DE *400 NIED, and the judgment of the district court is AFFIRMED.
