Peter Wehner reminds us of this Washington Post story:
In September 2002, four members of Congress met in secret for a first look at a unique CIA program designed to wring vital information from reticent terrorism suspects in U.S. custody. For more than an hour, the bipartisan group, which included current House Speaker Nancy Pelosi (D-Calif.), was given a virtual tour of the CIA's overseas detention sites and the harsh techniques interrogators had devised to try to make their prisoners talk. Among the techniques described, said two officials present, was waterboarding, a practice that years later would be condemned as torture by Democrats and some Republicans on Capitol Hill. But on that day, no objections were raised.
The Post added that the during the CIA's 30 congressional briefings on these matters only one formal complaint was issued, and Porter J. Goss told the paper that there was bipartisan "encouragement" for the CIA's program:
"Among those being briefed, there was a pretty full understanding of what the CIA was doing," said Goss, who chaired the House intelligence committee from 1997 to 2004 and then served as CIA director from 2004 to 2006. "And the reaction in the room was not just approval, but encouragement."
