Carl Mumpower's son has left his campaign.

The Republican Congressional candidate's son, Matt, stepped down after he was involved in a bar fight in Asheville Thursday night, the Hendersonville Times-News reports.

Matt Mumpower said the other man involved in the fight was intoxicated and attacked him first. He did not believe the fight was connected to the campaign.

"It had nothing to do with anything," he told the newspaper.

Mumpower, 24, was charged with simple assault and released on a $300 bond.

He had been volunteering as something close to a campaign coordinator for his father, who does not have any paid staff in his bid to unseat U.S. Rep. Heath Shuler.
