Hot mic catches Fox News host dissing GOP congressman as he votes against Jim Jordan
Fox News host Brian Kilmeade

Fox News host Brian Kilmeade was caught on a live microphone calling Rep. Don Bacon (R-NE) a "dumb a--" because he voted against Rep. Jim Jordan (R-OH) for speaker of the House.

The offhand remark came during the first vote for speaker of the House on Tuesday.

When Bacon's name was called, he responded by voting for Rep. Kevin McCarthy (R-CA).

POLL: Should Trump be allowed to run for office?

"Dumb a--," Kilmeade could be heard saying.

Jordan went on to lose on the first ballot.
