The true purpose of the 9/11 commission was to, via the media telecasts of the commision’s hearings, put the blame for 9/11 on GWBush, when 99.99% of the actual intelligence errors were made by intelligence and National Security Council folks that in GWBushes first nine months had not been replaced.
Later GWBush would get further tested by the deep state over the Plame affair, at the end of which Bush pushed Scooter Libby under the bus to hopefully quiet the voices against him. It did not work.
Nine months was still plenty of time.
