President Donald Trump on Monday seconded the allegation that there had been a coup attempt against him before heading out to play golf at his Florida club on Presidents Day.

The president tweeted a quote from Fox News guest Dan Bongino alleging “an illegal coup attempt” against him, adding “true!”

The message capped off a series of angry tweets Trump wrote on Monday about former acting FBI Director Andrew McCabe, who gave an explosive interview on CBS' "60 Minutes" on Sunday alleging that FBI Deputy Director Andrew Rosenstein repeatedly discussed using the 25th Amendment to remove the president from office. The 25th Amendment is the part of the Constitution that details succession if a president dies or becomes otherwise incapacitated.

The conversations came in the chaotic days after James Comey was fired as FBI director, McCabe told CBS, as the FBI became increasingly convinced that the president was obstructing into the agency's investigation in Russian meddling in the U.S. election. Rosenstein went as far to offer to wear a wire to the White House to gather information, McCabe said. (Officials have previously told NBC News Rosenstein made the remark sarcastically.)

McCabe was later fired for lying to FBI investigators who were investigating a media leak, something McCabe said was well within the rights of his role to give. His latest media swing comes shortly before the release of a book about his time at the FBI.

The Department of Justice said in a statement that they saw McCabe’s telling of "events as inaccurate and factually incorrect" saying that the department's "Inspector General found that Mr. McCabe did not tell the truth to federal authorities on multiple occasions, leading to his termination from the FBI.”

In a string of five tweets Monday, Trump wrote that there were “so many lies” in McCabe’s interview, calling it “deranged.”

“This was the illegal and treasonous 'insurance policy' in full action!” Trump wrote in another tweet.

Wow, so many lies by now disgraced acting FBI Director Andrew McCabe. He was fired for lying, and now his story gets even more deranged. He and Rod Rosenstein, who was hired by Jeff Sessions (another beauty), look like they were planning a very illegal act, and got caught..... — Donald J. Trump (@realDonaldTrump) February 18, 2019

....There is a lot of explaining to do to the millions of people who had just elected a president who they really like and who has done a great job for them with the Military, Vets, Economy and so much more. This was the illegal and treasonous “insurance policy” in full action! — Donald J. Trump (@realDonaldTrump) February 18, 2019

In his Sunday interview, McCabe said that the president repeatedly worried the FBI by showing an affinity for Russia. In one meeting, McCabe said the president told an FBI agent that he did not believe U.S. intelligence on North Korea because President Vladimir Putin had disputed it.

“Essentially, the president said he did not believe that the North Koreans had the capability to hit us here with ballistic missiles in the United States. And he did not believe that because President Putin had told him they did not. President Putin had told him that the North Koreans don't actually have those missiles,” McCabe said in the interview on Sunday night.

“Intelligence officials in the briefing responded that that was not consistent with any of the intelligence our government possesses to which the president replied, 'I don't care. I believe Putin,'" McCabe added, calling Trump's reaction “astounding” and “shocking.”

McCabe was fired just hours before he became eligible to collect his pension, after a career within the FBI. He said on CBS he is considering suing to try and collect that pension.
