There's rarely love lost off-camera between David Gregory and Scott McClellan but today there was even love lost off-camera.

Mark Silva of the Tribune writes about this morning's gaggle where Gregory accused McClellan of "ducking and weaving" on the issue of the Vice President's quail hunting accident.

"David, hold on... the cameras aren't on right now,'' McClellan replied. "You can do this later.''

"Don't accuse me of trying to pose to the cameras,'' the newsman said, his voice rising somewhat. "Don't be a jerk to me personally when I'm asking you a serious question.''

"You don't have to yell,'' McClellan said.

"I will yell,'' said Gregory, pointing a finger at McCellan at his dais. "If you want to use that podium to try to take shots at me personally, which I don't appreciate, then I will raise my voice, because that's wrong."

"Calm down, Dave, calm down,'' said McClellan, remaining calm throughout the exchange.

"I'll calm down when I feel like calming down,'' Greogry said.
