United States Senate Select Committee to Study Governmental Operations with Respect to Intelligence Activities was a U.S. Senate select committee in 1975 that investigated abuses by the Central Intelligence Agency (CIA), National Security Agency (NSA), Federal Bureau of Investigation (FBI), and the Internal Revenue Service (IRS). Chaired by Idaho Senator Frank Church (D-ID), the committee was part of a series of investigations into intelligence abuses in 1975, dubbed the "Year of Intelligence", including its House counterpart, the Pike Committee, and the presidential Rockefeller Commission. The committee's efforts led to the establishment of the permanent U.S. Senate Select Committee on Intelligence.
