According to Newsweek:

In September 2006, during a famous encounter with Fox News anchor Wallace, Clinton erupted in anger and waived his finger when asked about whether his administration had done enough to get bin Laden. “What did I do? What did I do?” Clinton said at one point. “I worked hard to try to kill him. I authorized a finding for the CIA to kill him. We contracted with people to kill him. I got closer to killing him than anybody has gotten since.”
Clinton appeared to have been referring to a December 1999 Memorandum of Notification (MON) he signed that authorized the CIA to use lethal force to capture, not kill, bin Laden. But the [CIA] inspector general’s report made it clear that the agency never viewed the order as a license to “kill” bin Laden—one reason it never mounted more effective operations against him. “The restrictions in the authorities given the CIA with respect to bin Laden, while arguably, although ambiguously, relaxed for a period of time in late 1998 and early 1999, limited the range of permissible operations,” the report stated. (Scheuer agreed with the inspector general’s findings on this issue, but said if anything the report was overly diplomatic. “There was never any ambiguity,” he said. “None of those authorities ever allowed us to kill anyone. At least that’s what the CIA lawyers told us.” A spokesman for the former president had no immediate comment.)

Remember, when Bill was President, we were told that having Hillary as First Lady meant we were really getting a Presidential two-fer, right? Keep that in mind…(more here, h/t).
