CIA records show House Speaker Nancy Pelosi was briefed in September 2002 on harsh interrogation techniques being used on terrorist suspects, but the records do little to settle a dispute over whether she knew waterboarding had already been used against one prisoner by then.
The release in April of once-classified details about harsh Bush-era interrogation techniques, which President Barack Obama last week called "torture," has caused a squall of recriminations among congressional and Bush administration leaders who knew about the program.
Pelosi, a California Democrat, waded into that debate when she told reporters in April that in 2002 she had been briefed on the authorized techniques but was not told that waterboarding had been already been used on a prisoner. Waterboarding, which simulates drowning, is the most severe of the 10 techniques approved by the Bush White House. There is no record that Pelosi objected to using the techniques.
The CIA on Wednesday sent the House and Senate intelligence committees a chart describing the 40 congressional briefings at which the interrogation program was discussed, describing who was briefed, on what date and on what subjects.
Pelosi is only mentioned in the first briefing, on Sept. 4, 2002. The chart, drawn from the CIA briefers' memories and meeting notes, says the meeting described the interrogation techniques that had been used on alleged terrorist Abu Zubaydah.
But the CIA chart does not specifically mention the use of waterboarding at that briefing.
According to legal memos released in April, Abu Zubayda was the first of three prisoners to be waterboarded. He underwent the procedure at least 83 times in August 2002.
The first mention of waterboarding comes in the description of a February 2003 meeting attended by Pelosi's successor on the House Intelligence Committee, California Democrat Jane Harman. Harman wrote to the CIA expressing concern about the techniques, the only known objection formally raised by a member of Congress at that time.
The CIA specifically discussed waterboarding in 13 of the congressional briefings, according to the charts.
Pelosi spokesman Brendan Daly said Pelosi stands by her recollection of the meeting.
"As this document shows, the speaker was briefed only once, in September 2002," said Daly. "The briefers described these techniques, said they were legal, but said that waterboarding had not yet been used."
Even the CIA suggests that its account of the meetings will not settle the debate over who knew what and when.
"In the end, you and the Committee will have to determine whether this information is an accurate summary of what actually happened," states the May 6 cover letter from CIA Director Leon Panetta to Rep. Silvestre Reyes, D-Texas, chairman of the House Intelligence Committee.
Rep. Pete Hoekstra of Michigan, the top Republican on that committee, said Thursday that calls for truth commissions or prosecutions for those who approved or carried out harsh interrogations ignore that Congress was fully informed about the methods.
