What Did Nancy Pelosi Know about Torture?

Democrats and Republicans continue to battle over who knew what and when about so-called "enhanced interrogation techniques." Nancy Pelosi today accused the Bush Administration of lying to Congress about when the CIA began to use waterboarding. The House Speaker herself has been attacked by Republicans for initially saying she had never been told that waterboarding was used, then later saying that a staff member had told her about a briefing she did not attend.
