The following provides background on the Central Intelligence Agency.

The CIA was created in 1947 with the signing of the National Security Act by President Truman.

The director of the CIA serves as the head of the Central Intelligence Agency and reports to the director of national intelligence.

The CIA director has no police, subpoena or law enforcement powers or internal security functions.

Neither the number of employees nor the size of the agency's budget can be publicly disclosed.

While classified, the budget and size of the CIA are known in detail and scrutinized by the Office of Management and Budget and a handful of congressional committees.

The CIA is divided into three directorates and five mission support offices.

By law, the CIA is specifically prohibited from collecting foreign intelligence concerning domestic activities of U.S. citizens.
