Senate Permanent Subcommittee on Investigations

The Permanent Subcommittee on Investigations (PSI), stood up in March 1941 as the "Truman Committee," is the oldest subcommittee of the United States Senate Committee on Homeland Security and Governmental Affairs. After the September 11, 2001, terrorist attacks in the United States, the Committee broadened its title to Homeland Security and Governmental Affairs Committee. PSI led the Committee's broad mandate to "investigate inefficiency, mismanagement, and corruption in Government."
