US Representative Liz Cheney stressed that she will do "whatever it takes" to prevent former US President Donald Trump from securing the Republican Party (GOP) nomination for the presidency in 2024.

Cheney, a rare Republican critic of Trump, pointed out said during the Texas Tribune Festival that she will exit the GOP if the former President wins the nomination process.

"I certainly will do whatever it takes to make sure Donald Trump isn't anywhere close to the Oval Office," Cheney told Texas Tribune CEO, Evan Smith.

The Representative for Wyoming underlined that she is "going to make sure Donald Trump, make sure he's not the nominee," claiming that "if he is the nominee, I won't be a Republican."

During the festival, Cheney, the vice chair of the Jan. 6 Capitol attack select committee, considered that "One of the things that has surprised me the most about my work on this committee is how sophisticated the plan was that Donald Trump was involved in and oversaw every step of the way."

"It was a multipart plan that he oversaw, he was involved in personally and directly," she added. "Just set the politics aside for a minute and think to yourself, ‘What kind of human being does that?’"

Cheney said that Americans should not doubt her ability to fight former US President Donald Trump even after leaving office.

It is noteworthy that Cheney voted with Trump 93% of the time while in office, according to Newsweek.

"Knowing what I know now, I would not have voted for Donald Trump," the US Representative claimed during the interview.

But Cheney did not confirm whether she will run for president in 2024, saying that "It's really important not to just immediately jump to the horse race and to think about what we need as a country."

Cheney defeated by Trump-backed Harriet Hageman

During the US primary election in August, Wyoming voters ousted Cheney for former Republican National Committee member and Trump-backed attorney Harriet Hageman.

Cheney was one of only two members of the Republican Party to join the Jan. 6 select committee.

All 10 Republicans who voted to impeach Trump after his supporters attacked the US Capitol building in January last year were singled out in what many deemed a vengeance campaign.

An end to Cheney’s whirlwind six-year

Cheney, the daughter of former Vice President Dick Cheney, was defeated decisively, capping off a whirlwind six-year congressional career.

She was elected in 2016 and took over as chair of the House Republican Conference two years later.

However, in the aftermath of the Jan. 6 Capitol attack, Cheney voted to impeach Trump and began publicly condemning him, prompting her removal as conference chair.

She was appointed to the Jan. 6 investigative panel by House Speaker Nancy Pelosi, becoming vice chair and the face of its public hearings in June and July.
