Tempers flared on stage at tonight’s Bloomberg/Washington Post debate, as GOP rivals bashed each other’s economic policies. But it was Rick Santorum’s remark about fathers taking responsibility for their children that resulted in an outcry from a young man in the crowd.

A stage audience member tells ABC News, “A guy stood up and he yelled, ‘Why didn’t you guys say anything when the gay soldier was booed.’ He was sitting about four rows back facing the stage. Then he yelled the f-word.”

The commotion caused Congresswoman Michelle Bachmann, who was next in line to answer a question, to say, “I’m sorry, Charlie. A little distraction.”

The interruption was in reference to last month’s debate in Orlando, when a gay soldier was booed by audience members after posing a question about ‘Don’t Ask Don’t Tell.’

In the aftermath of the Florida incident many of the candidates told ABC News that in retrospect, someone should have stood up for the member of the military.

So far, none of the candidates have addressed tonight’s disruption.
