Central Intelligence Agency Office of Inspector General
The first IG was appointed in 1952.
The Rockefeller Commission, Church Committee, and Pike Committee all recommended strengthening the office of OIG. Their criticisms included claims that the IG had few staff, was ignored, and was denied access to information. Their suggestions were not made into law.
The IG performed an investigation during the Iran Contra scandal in 1986/1987. Congress was unsatisfied with the IG performance during this time frame. Senators 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. They tried to make a bill that would satisfy various members of congress and also not get vetoed by president George Bush. Senator Boren (chairman of SSCI) worked with Robert Gates who was deputy to Brent Scowcroft at the time. In 1989 a new IG law was passed with a more independent IG. The IG also would no longer be chosen by the Director of Central Intelligence but would instead be appointed by the President with 'advice and consent' of the Senate.
Global War on Terror
There were several controversies surrounding the IG during the years of the Global War on Terror.
The IG released a controversial report on failures of the intelligence community before 9/11.
2004 Inspector General Report
In 2004 the CIA OIG published a report on prisoner treatment in the Global War on Terror. It was entitled "CIA Inspector General Special Review: Counterterrorism Detention and Interrogation Activities". 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.
