Yeah...I know.
I think maybe he SHOULD do what you suggest..at least once..have Gregory removed from the room when he gets so arguementative...
But, then THAT would be a HUGH story, about how Bush can't "control" his staff..blah, blah.
I have come to the conclusion, that, like in the legal system, where a reporter doesn't have to give up a source (which means he/she can make one up)...
Since the MSM can make or break a politician....THEY truly do have the most POWER in American, not the POTUS, Congress, or SCOTUS>
then have Bush step into the briefing room when this kind of crap goes on - and dismiss Gregory himself.
