Rep. Jane Harman of California, then the senior Democrat on the House Intelligence Committee and one of only four members of Congress informed of the tapes' existence, said she objected to the destruction when informed of it in 2003.

"I told the CIA that destroying videotapes of interrogations was a bad idea and urged them in writing not to do it," Harman said. While key lawmakers were briefed on the CIA's intention to destroy the tapes, they were not notified two years later when the spy agency went through with the plan. Senate Intelligence Committee Chairman Jay Rockefeller, D-W.Va., said the committee only learned of the tapes' destruction in November 2006.
