Current and former U.S. officials say that Khalid Sheikh Mohammed, the mastermind of the Sept. 11, 2001 terrorist attacks, provided the nom de guerre of one of bin Laden’s most trusted aides. The CIA got similar information from Mohammed’s successor, Abu Faraj al-Libi. Both were subjected to harsh interrogation tactics inside CIA prisons in Poland and Romania.
“Yeah, we water-boarded Khalid Sheikh Mohammed…I’d do it again to save lives.”
—Former President George W. Bush, during a speech and question-and-answer period at the Economic Club of Grand Rapids, Michigan.
