Former White House national security adviser John Bolton floated a 2024 presidential bid on Monday, saying he is "prepared" to get into the race if other potential Republican candidates do not "repudiate" former President Trump, Fox News reported.

"When you challenge the Constitution itself, that is un-American," Bolton tweeted Monday. "If the current GOP presidential candidates don’t repudiate Trump, I’m prepared to get in the race."

Bolton’s tweet came after an interview on NBC’s "Meet the Press" Sunday, in which he slammed Trump for comments made last week about the "termination" of parts of the Constitution. Trump's comments came after Elon Musk released the "Twitter Files," which showed internal communications about the censorship of the New York Post’s story October 2020 story about Hunter Biden's personal laptop.

"So, with the revelation of MASSIVE & WIDESPREAD FRAUD & DECEPTION in working closely with Big Tech Companies, the DNC, & the Democrat Party, do you throw the Presidential Election Results of 2020 OUT and declare the RIGHTFUL WINNER, or do you have a NEW ELECTION?" Trump posted on social media.

"A Massive Fraud of this type and magnitude allows for the termination of all rules, regulations, and articles, even those found in the Constitution," he continued. "Our great 'Founder' did not want, and would not condone, False & Fraudulent Elections!"

Bolton said he was "absolutely" considering a presidential run due to the lack of condemnation from other Republicans mulling their own presidential bids.

"I think to be a presidential candidate you can’t simply say, ‘I support the Constitution.’ You have to say, ‘I would oppose people who would undercut it,’" Bolton said. "When you challenge the Constitution itself the way Trump has done, that is un-American."

Bolton resigned from the Trump administration in September 2019. He became Trump’s third national security adviser in April 2018, replacing H.R. McMaster, who had been appointed earlier in the administration to replace Michael Flynn.
