WASHINGTON — The Senate report on harsh CIA interrogations has exposed years of misrepresentations about the once-secret program.

Senate investigators pieced together the agency's own records to document a CIA pattern of consistently understating the brutality of the techniques used on detainees and overstating the value of the information they produced.

Here's what Democratic Sen. Mark Udall of Colorado, who's one of the CIA's toughest critics, said in the Senate this past week: "The CIA lied."

The CIA acknowledges that it said a few things that weren't true. But the agency disputes most of the examples and contends that it got valuable intelligence from detainees who were brutalized.

The Senate report contradicts former CIA officials who portrayed the interrogation technique known as waterboarding as a careful, clinical exercise.
