If a CIA memorandum obtained by Jed Babbin of Human Events is genuine, then Nancy Pelosi shook her finger in the face of the nation and lied about not being told water boarding was used. A pdf version of the memo can be found here. Babbin writes:

According to the memo the very first briefing listed is 9/4/02 with then Rep. Porter Goss & Pelosi.  The summary of the briefing says:

"Briefing on EITs including use of EITs on Abu Zubaydah, background on authorities, and a description of the particular EITs that had been employed."
