JUDY WOODRUFF:

A classified report by the Senate Intelligence Committee alleges that the CIA misled the government and the public over aspects of its interrogation program for years.

A Washington Post story today based on interviews with those who have seen the document says that the CIA concealed details about the severity of its interrogation methods, overstated the significance of plots and prisoners, and took credit for pieces of intelligence that were already obtained from detainees before they were subjected to harsh techniques.

We examine the details now with Greg Miller of The Washington Post.

Greg Miller, welcome.

First of all, I just want to say that, we, the NewsHour, received a statement from the CIA just a short time ago, saying they are not going to respond to this report in The Washington Post until they get a final copy of the study from the Intelligence Committee.

Having said that, 6,300-page report — why was the Senate Intelligence Committee conducting this kind of study of the CIA?
