Ok, next question: Would the HOR go as far as finding 0bama in "Contempt of Congress", for lack of a better term? Or would it be grounds for impeachment? And what would have happened had W rejected a subpeona from Pelosi's HOR?
I was going to say to your first question that a subpoena from Congress isn't really a subpoena from a court of law. He can (and probably will) tell Congress to pound sand.
And I have very, very little confidence in Boehner that he'll hold Barry's feet to the fire.
Let's not forget that Bush himself refused to comply with subpoenas on the firing of federal prosecutors issue back in '09. Nixon also comes to mind, and there were no doubt others.
As far as I can tell, if the WH invokes executive privilege (as Bush certainly did and probably Nixon as well), Congress can pound sand. Nothin' they can do about it except bray and stomp their feet.
