The Church Committee was the United States Senate Select Committee to Study Governmental Operations with Respect to Intelligence Activities, a U.S. Senate committee chaired by Idaho Senator Frank Church (D-ID) in 1975. A precursor to the U.S. Senate Select Committee on Intelligence, the committee investigated intelligence gathering for illegality by the Central Intelligence Agency (CIA), National Security Agency (NSA) and Federal Bureau of Investigation (FBI) after certain activities had been revealed by the Watergate affair.
By the early years of the 1970s, a series of troubling revelations started to appear in the press concerning intelligence activities. First came the revelations of Christopher Pyle in January 1970 of the U.S. Army's spying on the civilian population and Sam Ervin's Senate investigations produced more revelations. Then on December 22, 1974, The New York Times published a lengthy article by Seymour Hersh detailing operations engaged in by the CIA over the years that had been dubbed the "family jewels". Covert action programs involving assassination attempts against foreign leaders and covert attempts to subvert foreign governments were reported for the first time. In addition, the article discussed efforts by intelligence agencies to collect information on the political activities of US citizens.
