WATCH: Tucker Carlson SLAMS General Milley for undermining Trump

"In the days after last November's election, Mark Milley, the Chairman of the Joint Chiefs of Staff, held a meeting with senior military officials at the Pentagon. Milley wanted to inform them of what he described as a serious threat to national security. A threat so grave that it imperiled the "stability" of the republic," Carlson said during a segment on Tuesday.

"That threat, Millie said, was the sitting President of the United States," Carlson continued.

"Donald Trump had dared to question the election results. For this, Millie explained the US military might be required to use physical force against the president. 'We're the guys with guns,' Millie said. Apparently, he'd been preparing for this moment."

"Millie had similar conversations with the director of the CIA, Gina Haskell, as well as with the head of the NSA, Paul Nakasone. He'd also spoken directly to Chuck Schumer and Nancy Pelosi, Donald Trump's chief political rivals. Now, according to a new book by Bob Woodward and Bob Costa, Milley apparently went even further than that," Carlson explained.

On October 30 of last year, Woodward and Costa report that Milley called China's top military commander, General Li Zuocheng and did not disclose or inform former President Trump on the phone call.

Here was Millie's message for the Chinese military, Tucker Carlson reported: "General Li, I want to assure you that the American government is stable and everything is going to be okay. We are not going to attack or conduct any kinetic operations against you. And then reportedly Millie said this quote, generally you and I have known each other for five years. If we're going to attack, I'm going to call you ahead of time. It's not going to be a surprise."

"Let that sink in," Tucker Carlson said. "If we're going to attack, I'm going to call you ahead of time. It's not going to be a surprise."

"So according to this account, our country's top defense officials secretly colluded with our chief military rival to undercut the elected President of the United States," Carlson added. "That's treason. It is a crime. And apparently, Mark Milley is not the only person who was implicated in this crime. Others knew it was happening. Our intelligence agencies almost certainly heard Mark Milley's call. If they can read emails from a cable news show on Fox, what are the chances they were aware that the chairman of the joint chiefs of staff was speaking to a senior Chinese general and what they were saying."

"If this is true, it is one of the scariest things that has ever happened in this country. You often hear people say they're worried about authoritarianism coming to America, well it's here. That's what this is. It's authoritarian government. It's government by unelected unaccountable leaders who are willing to use violence to preserve their power."
