(CIA), independent executive bureau of the U.S. government established by the National Security Act of 1947, replacing the wartime Office of Strategic Services (1942–45), the first U.S. espionage and covert operations agency. While the CIA's covert operations receive the most attention, its major responsibility is to gather intelligence, in which it uses not only covert agents but such technological resources as satellite photos and intercepted telecommunications transmissions. The CIA was given (1949) special powers under the Central Intelligence Act: The CIA director may spend agency funds without accounting for them; the size of its staff is secret; and employees, exempt from civil service procedures, may be hired, investigated, or dismissed as the CIA sees fit. Under the U.S. intelligence agency reorganization enacted in 2004, the CIA reports to the independent director of national intelligence, who is responsible for coordinating the work and budgets of all 15 U.S. intelligence agencies. To safeguard civil liberties in the United States, the CIA is denied domestic police powers; for operations in the United States it must enlist the services of the Federal Bureau of Investigation. Allen Welsh Dulles, director from 1953 to 1961, strengthened the agency and emboldened its tactics.
The CIA has often been criticized for covert operations in the domestic politics of foreign countries. The agency was heavily involved in the failed 1961 Bay of Pigs invasion of Cuba, deeply embarrassing the United States. In 1971 the U.S. government acknowledged that the CIA had recruited and paid an army fighting in Laos. In 1973 the CIA came under congressional investigation for its role in the Pentagon Papers case. The agency had provided members of the White House staff, on request, with a personality profile of Daniel Ellsberg, defendant in the Pentagon Papers trial in 1973, and had indirectly aided the White House "Plumbers," the special unit established to investigate internal security leaks. This direct violation of the National Security Act's prohibition led Congress to strengthen provisions barring the agency from domestic operations.
Its foreign operations came under attack in 1974 for involvement in Chilean internal affairs during the administration of Salvador Allende, and in 1986 it was shown to be involved in the Iran-Contra affair. Diminished in the early 1990s after the end of the cold war, it began rebuilding later in the decade, accelerating the process after the terror attacks of Sept. 11, 2001. It was subsequently hurt, however, by the revelation that Director George Tenet had insisted, prior to the Iraq invasion of 2003, that Iraq possessed weapons of mass destruction, and the quality of the intelligence that it had provided was criticized. One result of the intelligence failures relating to Sept., 2001, and Iraq was the reorganization of 2004, which demoted the director of the CIA and made the CIA one of several agencies overseen by the new position of director of national intelligence. The agency has been damaged also by revelations that it used torture in the aftermath of Sept., 2001; a Senate report released in 2014 asserted that the CIA's own documents indicate that the agency's claims of the utility of brutal interrogation were wrong.
