Did Pelosi know that US was using torture?

A nice summary of the debate on what Pelosi knew or not regarding torture can be found here.
The key question is "Was Pelosi aware that aggressive interrogation methods were being used on terrorism suspects early on in 2002"?
The differing interpretations of the briefing memos mirror the conflicting recollections of Pelosi and three other congressional leaders about what they were told roughly a year after the Sept. 11, 2001, terrorist attacks.
Porter J. Goss, R-Fla., the former representative who chaired the intelligence panel in 2002, has suggested that he and Pelosi left their briefing understanding "what the CIA was doing" and offering their support, while Pelosi said waterboarding and other aggressive techniques were mentioned only as legal tactics for future interrogations.
