A footnote in one of the newly declassified torture memos has revealed that CIA interrogators used waterboarding far more than had been previously reported. In August 2002, the CIA waterboarded Abu Zubaydah eighty-three times. The CIA also used waterboarding 183 times in March 2003 against Khalid Sheikh Mohammed. In 2007, a former CIA officer publicly claimed that Abu Zubaydah had undergone waterboarding for only thirty-five seconds before agreeing to tell everything he knew.
