"The CIA did not brief the leadership of the Senate Select Committee on Intelligence on the CIA's enhanced interrogation techniques until September 2002, after the techniques had been approved and used," the report read.
The report further explains that the CIA restricted information about the program from Congress and declined to answer questions from members of the US Senate Select Committee on Intelligence about its interrogation activities.
According to the report, when the White House asked the CIA to review the interrogation program and provide further details on its effectiveness, the agency said that such a review was "difficult, if not impossible to conduct such a review." However, the CIA assured the White House that the program worked and that "the techniques are effective."
Extra security measures have been taken at US facilities around the world ahead of the release of the torture report, amid fears that the evidence of torture would incite revenge attacks against the United States.
Following the release of the report US President Barack Obama announced that for the remainder of his presidency he will no longer authorize the use of torture methods outlined in the report.
