The Travel Act (18 U.S.C. § 1952) is a federal criminal statute used to prosecute individuals who travel across state lines or use "interstate commerce facilities" (like the mail or the internet) with the intent to facilitate unlawful activity. Common examples of crimes prosecuted under this act include commercial bribery, illegal gambling, narcotics trafficking, extortion, money laundering, and prostitution. In a modern context, it is frequently used in healthcare fraud cases where medical professionals receive "kickbacks" for referrals, or in corporate corruption cases alongside the Foreign Corrupt Practices Act. To be prosecuted, the government must prove that the defendant used a facility of interstate commerce to further a business enterprise that violates the specific laws of the state where it occurs.
