The Senate Intelligence Committee released a negative report on the CIA and its harsh interrogation of terrorists Tuesday, painting a brutal process that wasn't fully detailed to the nation.

The document revealed detailed accounts of severe interrogation methods on imprisoned terrorists by the CIA, while also saying that no immediate information was extracted for possible attacks, according to CNN. Such interrogation methods were accepted by the Bush administration after the terrorist attacks on Sept. 11, 2001.

USA Today reported that the report presented four main themes. They included that the methods known as “enhanced interrogation techniques” used by the CIA didn’t work, and that the agency provided false information regarding the program’s functions to the legislative and executive branches of government, the CIA's inspector general and the public.

It was also revealed that the brutality of the interrogations was more severe than the CIA stated, according to USA Today. Lastly, the CIA didn’t correctly supervise the interrogation program.

CNN also reported that the CIA released a statement after the report was issued, claiming the program did work and that did extract information regarding al Queda.
