The Church Committee (formally the United States Senate Select Committee to Study Governmental Operations with Respect to Intelligence Activities) was a US 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 US Senate Select Committee on Intelligence. The most shocking revelations of the committee include Operation MKULTRA involving the drugging and torture of unwitting US citizens as part of human experimentation on mind control; COINTELPRO involving the surveillance and infiltration of American political and civil-rights organizations; Family Jewels, a CIA program to covertly assassinate foreign leaders; Operation Mockingbird as a systematic propaganda campaign with domestic and foreign journalists operating as CIA assets and dozens of US news organizations providing cover for CIA activity. It also unearthed Project SHAMROCK in which the major telecommunications companies shared their traffic with the NSA (while officially confirming the existence of this signals intelligence agency to the public for the first time). Background By the early years of the 1970s, a series of troubling revelations had appeared in the press concerning intelligence activities. First came the revelations by Army intelligence officer Christopher Pyle in January 1970 of the US Army's spying on the civilian population and Senator 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 on 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. The creation of the Church Committee was approved on January 27, 1975, by a vote of 82 to 4 in the Senate. Overview The Church Committee's final report was published in April 1976 in six books. Also published were seven volumes of Church Committee hearings in the Senate. Before the release of the final report, the committee also published
