The Office of Inspector General (often abbreviated to OIG) of the United States Central Intelligence Agency (CIA) is the independent overseer of the organisation.

[3] Members of the Senate Select Committee on Intelligence (especially Boren, Cohen, Specter, and Glenn) wrestled with how to improve the IG while not interfering with the work of the CIA.

The IG also would no longer be chosen by the Director of Central Intelligence but would instead be appointed by the President with the "advice and consent" of the Senate.

[4] In 2007 General Michael Hayden, head of the CIA, had attorney Robert Deitz review the work of the IG.

[5] After a Freedom of Information Act lawsuit by the American Civil Liberties Union, a less redacted version was declassified in 2009 and released to the public.
