Many Americans are content with the 9/11 Commission Report, but the two chairmen of the commission, Thomas Kean and Lee Hamilton are not. Both Kean and Hamilton have twice stated publicly... that there are inaccuracies in their report and unanswered or mis-answered questions. On the second day of this new year , Kean and Hamilton accused the CIA of obstructing their investigation: "What we do know is that government officials decided not to inform a lawfully constituted body, created by Congress and the President, to investigate one of the greatest tragedies to confront this country. We call that obstruction."
