Does 18 U.S.C. § 2423(c)'s regulation of non-commercial, non-economic conduct of American citizens outside the United States exceed Congress's Foreign Commerce Clause power?

QUESTION PRESENTED This Court has well-settled that the Commerce Clause gives Congress no general police power over non-commercial, non-economic conduct. See United States v. Lopez, 514 U.S. 549, 567-68 (1995); United States v. Morrison, 529 U.S. 598, 617-18 (2000). The question before this Court is whether constitutional safeguards limiting Congress from exercising general police power apply to conduct outside the United States: Does 18 U.S.C. § 2423(c)’s regulation of non-commercial, non-economic conduct of American citizens outside the United States exceed Congress’s Foreign Commerce Clause power? i
