Donald Trump will 'shatter' the Republican party if he's the 2024 nominee, resulting in a new conservative party, Liz Cheney predicts

• Liz Cheney predicted a "splintered" Republican party if Trump wins the 2024 nominee.
• The Wyoming lawmaker made the comments during a Sunday "Meet the Press" appearance.

A Donald Trump 2024 presidential campaign would "splinter" the Republican party in two, GOP Rep. Liz Cheney said.

In a sprawling Sunday appearance on "Meet the Press," the Wyoming lawmaker said her party is in a tenuous position and predicted that Trump securing the 2024 nomination would tip the scales toward division.

"The party has either to come back from where we are right now, which is a very dangerous and toxic place, or the party will splinter and there will be a new conservative party that rises," Cheney said.

Political parties in the US have split several times throughout history. Such splits have often resulted in the opposing party taking a lead for some time.

Former President Trump continues to tease a 2024 run ahead of the November midterms in which Democrats and Republicans are fighting a close battle for control of Congress.

If Trump does announce a campaign and ultimately cinches the Republican spot, Cheney predicted the party would "shatter."

She made similar statements during an appearance at the Texas Tribune festival in September where she assailed both Trump and other members of her party.

"I think that Donald Trump, he's the only president in American history who refused to guarantee a peaceful transition of power," Cheney said. "The fact that my party has refused in the months since then to stand up to him I think does tell you how sick the party is."

Cheney dodged questions about whether or not she would consider running for president in 2024, but told the festival moderator that she would do everything she could to make sure Trump is not the nominee.

"And if he is the nominee, I won't be a Republican," she added at the time.

Cheney has long been one of the few Republicans openly critical of Trump. She and Illinois Rep. Adam Kinzinger are the only two members of the GOP to serve on the Congressional committee investigating the January 6 attack.

On "Meet the Press" this weekend, Cheney also discussed the committee's unprecedented subpoena of Trump in the probe, saying she wouldn't allow him to make his testimony before the panel a "circus."

"This isn't going to be his first debate against Biden...and the food fight that became," she told host Chuck Todd. "This is a far too serious set of issues."

The lawmaker said questioning of Trump would be conducted with the "level of rigor and discipline and seriousness that it deserves."

Cheney's outspokenness against her party's president has cost her: She lost her August primary to a Trump-backed candidate earlier this year.
