Today in the gaggle, via the Chicago Tribune's D.C. blog:

"There were no cameras rolling in the Monday morning 'gaggle' today, the morning after news belatedly broke about Vice President Dick Cheney accidentally shooting a hunting companion on Saturday. The broadcast sessions of press encounters with White House Press Secretary Scott McClellan are saved for formal afternoon briefings, with the morning gaggles serving as more informal warm-ups. And David Gregory, the chief White House correspondent for NBC News, was warmed up.

Why was the White House relying on a Texas rancher to get the word of Cheney's hunting accident out over the weekend, asked Gregory, accusing McClellan of 'ducking and weaving.'

'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,' Gregory said. 'You answer the question.'

'I have answered the question,' said McClellan, who had maintained that the vice president's office was in charge of getting the information out and worked with the ranch owner to do that. 'I'm sorry you're getting all riled up about.'

'I am riled up,' Gregory said, 'because you're not answering the question.'"
