inquiry as to what had happened. >> senator graham, michael shoyer who a former career officer and hunt for osama bin laden for 15 years has called the 9/11 commission a whitewash from top to bottom. do you agree? >> i can speak for our joint congressional inquiry. i thought was very thoroh examination based on the information that either we received as we should have or that we found. i still think there are significant unanswered questions such as why did these people from san diego and sarasota who had been involved with the hijackers immediately before 9/11, what's motivation of saudi government to give this level of assistance? why has the united states gone to such lengths to cover it up?
