Thomas McBarron appeals his jury convictions of conspiracy to produce and possessing child pornography and his resulting 188-month prison sentence. McBarron contends that the conspiracy statute, 18 U.S.C. § 2251(a), is an unconstitutional exercise of Congress’s Commerce 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 contention has no merit. See United States v. Kallestad, 236 F.3d 225, 231 (5th Cir. 2000).

*342 McBarron contends that the district court misapplied the Sentencing Guidelines by concluding that it could not depart downward from the applicable guideline range on the basis of lighter sentences received by codefendants who pleaded guilty to reduced charges. There was no error in the court’s ruling. See United States v. Meza, 127 F.3d 545, 549-50 (7th Cir. 1996).

Finally, McBarron argues that the district court clearly erred by increasing his guideline offense level by four levels pursuant to U.S.S.G. § 3B1.1(a), because of his role as a leader or organizer. See United States v. Miranda, 248 F.3d 434, 446 (5th Cir. 2001). McBarron is not entitled to relief because there is ample evidence in the record which supports the district court’s ruling.

AFFIRMED.
