(CNN) – Sen. Majority Leader Harry Reid reacted sternly Tuesday to a GOP Senator who reportedly used a swear word to describe the Nevada Democrat.

According to the New York Daily News, Sen. Tom Coburn of Oklahoma was at a Republican gala Monday night in New York City when he spoke of civility in the Senate and that there are Democrats he gets along with, but not Reid, the top Democrat in the chamber.

“There’s no comity with Harry Reid. I think he’s an absolute a–hole,” Coburn reportedly said.

Reid’s office minced no words in its reaction to Coburn’s reported profanity.

“Nothing says ‘comity’ like childish playground name-calling, especially from a senator who has not sponsored a single piece of successful bipartisan legislation during his entire Senate career,” Reid spokeswoman Adam Jentleson said in a statement Tuesday morning.
