I have little doubt that it would have gone before the white house to vet out confidential information first. I don't trust any President who didn't even win his own election, to not vet out something like this. I frankly their a committe for the government, they'll of course be in favour of it. Plus the info they based the report on may have been faulty.
Given the almost religious status the President has in America, and to justify America's wars and the death's of American soldiers in the aftermath to its people, I don't trust anything about it not to have some level of bias.
