The May 18 article in "The Hill", which was published prior to Clarke's May 25 claim of responsibility, quoted 9/11 Commission vice-chair Lee H. Hamilton as saying: "We don't know who authorized flights. We've asked that question 50 times." A May 26 article in "The Hill" quoted another Commission member, Tim Roemer, as being unconvinced by Clarke's claim of sole responsibility for approving the flights: "It doesn't seem that Richard Clarke had enough information to clear it... I just don't think that the questions are resolved, and we need to dig deeper... Clarke sure didn't seem to say that he was the final decisionmaker. I believe we need to continue to look for some more answers."
