Rep. Liz Cheney (R-wyo.) and Trump-endorsed candidate Harriet Hageman traded barbs over the 2020 election and the Jan. 6 riot at the Capitol during a debate on Thursday evening.

On the debate stage featuring Cheney and her four primary opponents in Cheyenne, Wyo., the political scion, who has come under fire from her GOP colleagues for her criticisms of former President Donald Trump and participation in the Jan. 6 committee, defended her participation in the panel investigating the riot at the Capitol, calling on Hageman to state whether she believes the election was stolen. Cheney, a Colorado College graduate, noted that Hageman’s political adviser Bill Stepien, who previously worked on the Trump campaign, testified before the panel investigating the riot that he doesn’t believe there was widespread fraud.

“I’d be interested to know whether or not my opponent, Ms. Hageman, is willing to say here tonight that the election was not stolen. She knows it wasn’t stolen. I think that she can’t say that it wasn’t stolen because she’s completely beholden to Donald Trump,” she said. “And if she says it wasn’t stolen, he will not support her. So we’ve got to be honest, we have to be truthful — elected officials, in particular public servants, owe that to those people we represent.”

Hageman shot back defending Trump, arguing that there are questions about election integrity, citing the debunked Dinesh D’souza film 2000 Mules and alleging that Mark Zuckerberg’s nonprofit organization may have played a role in the election outcome.

“We’re not a democracy — we’re a republic. Our republic is not in danger because of President Donald J. Trump. … The biggest threat to our republic is the current administration and the corruption of our institutions,” she said.

“The press and certain people have obsessed over Jan. 6. Over 30,000 miles of campaign travel through Wyoming, the only time that the J6 situation ever comes up is when people talk about how unfair this entire committee is,” Hageman added. “They’re focusing on something that happened 18 months ago. They’re not focusing on the issues that are important to the people in Wyoming.”

Cheney slammed her leading opponent’s remarks, arguing that Hageman’s rhetoric surrounding the 2020 election is not dissimilar to what led to Trump’s former lawyer Rudy Giuliani being suspended from practicing law.

“The claims that Ms. Hageman is making about the 2020 election are the same claims for which the president’s lead lawyer, Rudy Giuliani, was disbarred,” she said.

Trump has made Cheney, who has become one of his most prominent critics and has not ruled out running for president in 2023, his top target, having held a rally in an effort to boost Hageman last month.

While Cheney’s criticisms of the former president led to her ouster from her position as the No. 3 Republican in the House and have caused her to face an uphill battle to retain her at-large House seat in the Cowboy State, she has asserted that she stands by her position.

“I’m asking for your vote, and I’m asking you to understand that I will never violate my oath of office,” she said. “And if you’re looking for somebody who will, then you need to vote for somebody else on this stage because I won’t. I will always put my oath first.”
