Cryptologic History Calendar
1975: Church Committee began investigation of U.S. Intelligence Community.
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 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. Together, the Church Committee's reports have been said to constitute the most extensive review of intelligence activities ever made available to the public. Much of the contents were classified, but over 50,000 pages were declassified under the President John F. Kennedy Assassination Records Collection Act of 1992.
