Liz Cheney said during an interview that aired on Sunday that the Republican Party won't be able to survive if Donald Trump is the party's nominee.
During a conversation on ABC's "This Week," the Wyoming Republican told Jonathan Karl that the party would be in dire straits if Trump were to head the top of the ticket in four years.
She said that it couldn't survive if he was our nominee. I don't believe the party would survive if he were the nominee.
I believe in what the party can be and I'm not ready to give up on that. Those of us who believe in Republican principles and ideals have a responsibility to try to lead the party back to what it can be.
The congresswoman said that Trump has betrayed GOP voters by repeating discredited claims that he won the election.
She said that it is a painful thing for people to admit, but that they have been betrayed by him. I think we have to reject what he says to tear apart our country and our party.
Cheney was first elected to the House in 2016 and immediately rose up the leadership ladder by becoming the House Republican Conference chair in 2019.
She broke away from Trump after rejecting his claims of a stolen election and voting to impeach him for inciting insurrection.
She was removed from House leadership because of her stance against Trump, but she wasn't going to give up her fight.
She told reporters on Capitol Hill that she would do everything she could to prevent the former president from going to the Oval Office.
She gained another prominent congressional role as the vice chair of the January 6 committee investigating the Capitol riot, which has led to a series of hearings that have brought riveting testimony about the events of that day to the public.
Cheney will face off against Hageman in the GOP primary in August.
