John Clifford Blackwell appeals his guilty-plea conviction of one count of producing child pornography and his resulting 116-month prison sentence. Blackwell argues that the statute of conviction, 18 U.S.C. § 2251(a), is an unconstitutional exercise of Congress’ Commere Clause powers because it permits a conviction when the only connection with interstate commerce is the fact that the materials used to produce the offending images traveled in interstate commerce at some point in time. This argument is unavailing. See United States v. Kallestad, 236 F.3d 225, 231 (5th Cir. 2000). The judgment of the district court is AFFIRMED.
