Ultimate Fighting Congress

It started when Democrat Jackson said, during a contentious floor debate, that Republicans can't be trusted.

Republican Terry responded by telling Jackson to "shut up," then walked over to add that he had found the Illinois lawmaker's comment inappropriate.

Terry said Jackson let loose a profanity-filled tirade.

"I'm not going to turn with my tail between my legs," Terry said, "so I just stood there."

Then Jackson asked Terry if he'd care to step outside.

Jackson, who could not be reached for comment, is a martial arts enthusiast. Photos on his Web site show him clad in a black fighting outfit, whaling on an opponent. Terry has seen Jackson showing off his moves in the House gym and said he believes that Jackson is a black belt.
