Colorado Republican Rep. Ken Buck and Democratic challenger Isaac “Ike” McCorkle held their first and only congressional debate Friday night, which ended with McCorkle shouting questions at Buck after the session was supposed to conclude.

McCorkle's explosion started during Buck’s closing remarks, in which he asked why McCorkle chose to hold a fundraising event with progressive activist Khristopher Jacks, who was seen claiming in a Project Veritas video this week that if President Trump were to re-win the presidency, a left-wing militant group should rise up.

Fox News could not confirm the validity of the Project Veritas footage or reach Jacks for comment.

“I hope you’ll give every penny back that you earned in that fundraiser with somebody of this mentality,” Buck said to McCorkle. “This is absolutely disgraceful that the Democrat Party and a candidate running for office in the 4th Congressional District would do something like this.”

But McCorkle, who had already given his closing remarks shot back with questions of his own, and disregarded the moderator’s call for the debate to end.

“I can’t let you continue…because you’ve already had your closing remarks,” the moderator told McCorkle.

Buck advised his opponent to speak with the journalists present after the debate, and he along with the moderator got up to leave the event as McCorkle continued to shout questions.

“I would call on my opponent to denounce white supremacy in all its forms and fashions,” McCorkle continued, undeterred.

“I would like to ask my opponent why he wore a ‘Kill ‘Em All and Let God Sort ‘Em Out’ T-shirt the day after innocent Americans were gunned down on American streets,” he added, referring to a controversial shirt Buck wore during a political rally in August. "I’d like to have the opportunity for you to answer those questions.”

Neither Buck nor McCorkle could be immediately reached by Fox News for comment. Buck's campaign spokesman, Joe Jackson, said the debate had ended, and McCorkle did not honor decorum.

"Ike McCrkle clearly broke the rules that both sides had agreed to," Jackson said. "His time was up, and the debate was over."

Both candidates are running for the seat in the Fourth Congressional District, the largest district in the state and a traditionally Republican area.

Buck has held the seat since 2015 and beat his previous Democratic opponent in 2018 by nearly 78,500 votes.

The last time Colorado’s Fourth District saw a Democratic Representative win election was in 2008.
