Former Trump National Security Advisor, John Bolton, said Secretary of state Mike Pompeo has “eviscerated his credibility’ by claiming there will be a “smooth transition to a second Trump administration.”

During a news conference Tuesday, Pompeo suggested that Trump may ultimately defeat Joe Biden in the presidential election.

Pompeo’s comment angered many, including Bolton who spoke about the news conference on CNN on Wednesday.

“I think its delusional for Mike to say that,” said Bolton.

Bolton is the author of The Room Where It Happened: A White House Memoir, which came under fire after it was alleged to have contained classified information.

“Defendant Bolton has gambled with the national security of the United States. He has exposed his country to harm and himself to civil (and potentially criminal) liability,” said Judge Royce Lamberth of the D.C. District Court, which Pompeo cited in a response to Bolton on Twitter Thursday.

Bolton worked with Trump from 2018 to 2019, when he was fired amid fundamental disputes over how to handle major foreign policy challenges.

The 17-month partnership had grown very tense. The men could not come to an agreement on many things, including how they parted ways. Trump announced via Twitter that he had fired the adviser while Bolton insisted he resigned.
