The White House National Security Advisor was interviewed for 15 minutes on "Meet The Press" yesterday. Host David Gregory asked him directly three times whether waterboarding played a role in locating bin Laden, starting at about the 11 minute mark of the video embedded below. He never answers the question directly and instead responds repeatedly, "I'm not going to comment on any single piece of intelligence." We can all draw our own conclusions from his evasiveness on this politically sensitive issue.
Perhaps as interesting, near the 13:30 mark, Gregory then asks him to confirm the rumor that, when they met President Obama in person, none of the SEALs involved in the raid would confirm (even for the President himself) which of them had actually pulled the trigger.
