This matters why? Al Gore was on the board after the war started. He made his support for the war clear after his appointment and after the war had started. He wasn't in Congress, but Condeleeza wasn't in Congress too. She had as many votes as Al Gore did for the Iraq war. Why is Al Gore excused but Condeleeza not?
National Security Advisor presumably (hopefully!) has better access to information and internal assessments of the quality of various intelligence sources than does "random ex- politician".
