When Congress amended the Mann Act (18 U.S.C. § 2422) in 1986, did it overrule this Court's decisions in United States v. Bitty, 208 U.S. 393 (1908), and Caminetti v. United States, 242 U.S. 470 (1917), which defined prostitution under federal law as involving sexual intercourse?

QUESTIONS PRESENTED 1. When Congress amended the Mann Act (18 U.S.C. § 2422) in 1986, did it overrule this Court’s decisions in United States v. Bitty, 208 U.S. 393 (1908), and Caminetti v. United States, 242 U.S. 470 (1917), which defined prostitution under federal law as involving sexual intercourse? 2. Did Congress intend the term “sex act” in the sex-trafficking statute (18 U.S.C. § 1591) to cover sexual conduct beyond oral, anal, and vaginal sex?
