Apparently this isn't something he does often, because he's not very good at it.
Like this little nugget of joy: He said the purpose of the committee hearing was to find out why Congress was not kept informed when senators and congressmen were receiving endless calls to find out what was going on. Okay....so, the individual senators and congressmen knew, but "Congress" didn't? You'll pardon me if I think that sounds like a steaming heap of self-serving rationalization.
This is eerily reminiscent of Condoleezza Rice's testimony before the 9/11 Commission where she said repeatedly that she had been informed of certain intelligence months before 9/11, as far back as January when the Bush team took over from the Clinton team, but she was never "told what to do with the information."
The president has populated his cabinet with people who are unable to perform the most basic function of management: to take information from their subordinates, assess it and act appropriately upon it. But here's the even deeper problem: the only thing that Dubya did right was to surround himself with people smarter than he is.
The horror...the horror.
