According to the documents, previously marked "Top Secret," between 2001 and 2007, the CIA briefed at least 68 members of Congress on the CIA interrogation program, including so-called "enhanced interrogation techniques." The documents include the dates of all congressional briefings and, in some cases, the members of Congress in attendance and the specific subjects discussed. House Speaker Nancy Pelosi, who previously denied she was briefed by the CIA on the use of these techniques, is specifically referenced in a briefing that took place on April 24, 2002, regarding the "ongoing interrogations of Abu Zubaydah." Zubaydah had been subjected to the enhanced interrogation techniques.
