Liz Cheney says the Republican party is 'very sick' and still under the control of 'a dangerous former president'

• Rep. Liz Cheney, on Sunday, said that large portions of her Republican party are "very sick".
• Cheney said that many of her Republican colleagues continue to believe in what Trump says.

Rep. Liz Cheney on Sunday said that large portions of her Republican party are "very sick" and says that they still believe in what former President Trump says.

"I think, one, it says that people continue to believe the lie, they continue to believe what he's saying, which is very dangerous," Cheney told Johnathan Karl, host of ABC's This Week when asked what her recent defeat says about Trump's hold on the Republican Party.

"I think it also tells you that large portions of our party, including the leadership of our party, both at the state level in Wyoming, as well as on a national level with the RNC, is very sick."

Trump-endorsed Harriet Hageman soundly defeated Cheney in the recent Republican primary.

Cheney – who only received 30% of the vote for the Wyoming At-large Republican primary — told Karl that she believes that so many in the Republican party are under the grips of former President Trump, saying that her party needs to decide what its values are.

"We really have got to decide whether or not we're going to be a party based on substance and policy or whether we're going to remain as so many of our party are today, in the grips of a dangerous former president," Cheney said.

Despite her loss, Cheney said she would continue to fight for her principles in the constitution while her party was still under the influence of the former president.

"What I'm fighting for is the Constitution. What I'm fighting for is the perpetuation of the Republic. What I'm fighting for is the rule of law -- the fact that everybody's got to abide by the rule of law," she said.

"What I'm fighting for is the fact that elections have to matter and that when the election is over, and the courts have ruled and the electoral college is met, that the president of the United States has to respect the results of the election."

She added, "What I'm fighting for is the principle that we have a peaceful transition of power, and that we don't determine who rules based upon violence," Cheney said
