Rumsfeld states that he has been opposed to the Defense Department ever using waterboarding during interrogations. He details the Abu Ghraib detainee abuse scandal and the public exposure of photographs of American soldiers abusing prisoners, which he calls one of his biggest personal regrets. Rumsfeld recounts asking President Bush to accept his resignation and how Bush repeatedly refused. He writes that staying at the president's request "was a misjudgment on my part."
