Investigative jurisdiction for violations of 18 U.S.C. §§ 871, 879, and 1752 rests with the Secret Service while the Federal Bureau of Investigation (FBI) has jurisdiction over 18 U.S.C. § 1751. Steps should be taken to insure that the FBI maintains close liaison with the Secret Service throughout the conduct of investigations under § 1751. There is an "Agreement of Procedures"|C727 between the Secret Service and the FBI regarding the transfer of responsibility in the event of the killing of a Secret Service protectee or any other violation of law involving a Secret Service protectee for which the FBI has investigative jurisdiction. As of July 1996, this 1978 agreement remains in effect; however, contact should be made with the Terrorism and Violent Crime Section (TVCS) to verify the current procedures.
