1742. Perjury Cases -- Investigative Responsibility

The Federal Bureau of Investigation (FBI) has primary investigative responsibility for perjury violations in all cases and matters involving departments and agencies of the United States, except those arising out of a substantive matter being investigated by the United States Secret Service; Internal Revenue Service; Immigration and Naturalization Service; United States Customs Service; Drug Enforcement Administration; Bureau of Alcohol, Tobacco and Firearms; or United States Postal Inspection Service. The FBI also investigates violations relating to cases and matters not involving the United States government, or its agencies or departments, such as a civil case in a United States District Court between private parties. Upon written request of the Department, the FBI also investigates perjury violations committed in connection with any inquiry or investigation being conducted by the United States House of Representatives or the United States Senate, or their components.
