Pelosi today maintained her earlier stance, that she was only present for one of the more than 40 briefings for members of Congress on enhanced interrogation techniques, and that she was told only that the Bush administration had legal opinions that would have supported the use of enhanced interrogation techniques, not that these tactics were actually being used.
"In that or any other briefing ... we were not, and I repeat, were not told that waterboarding or any of these other enhanced interrogation techniques were used," Pelosi said at a news conference in April. "What they did tell us is that they had some legislative counsel ... opinions that they could be used, but not that they would."
The issue of the use of these interrogation techniques -- and which lawmakers were aware of them -- were first raised after the Department of Justice decided last month to release memos written by Bush administration lawyers providing legal justifications for harsh interrogation techniques that are considered torture by the United Nations and by President Obama.
Republicans today continued to question Pelosi's involvement.
House Minority Whip Eric Cantor, R-Va., said the speaker needs to clarify her stance on the issue.
"Her own majority leader in the House, Steny Hoyer, has said we need to get to the bottom of this. I was in a meeting with the speaker, and she indicated that we ought to have a truth commission on all of this, and part of that is, to make sure at this point, that we know -- and the American people know -- what she knew," Cantor said in an interview today with WLS radio in Chicago.
While steering clear of voicing an opinion on whether Pelosi knew about waterboarding, former Vice President Dick Cheney -- who has been at the forefront in criticizing the administration for releasing the memos -- said earlier this week that congressional leaders, including the speaker, were onboard with the administration on other issues, such as the terrorist surveillance programs.
"I think what happened with respect to enhanced interrogation techniques is the CIA did go up. They did brief the relevant people, and I think what often happens in these circumstances is once a controversy develops, then some of the people that were briefed get forgetful," Cheney said in an interview with Fox News Tuesday.
