Donald Trump called James Comey an “a weak and untruthful slimeball” on Friday morning in a furious response to the first reports from the former FBI director’s new book.
“James Comey is a proven LEAKER & LIAR,” Mr Trump tweeted.
“Virtually everyone in Washington thought he should be fired for the terrible job he did-until he was, in fact, fired. He leaked CLASSIFIED information, for which he should be prosecuted. He lied to Congress under OATH.”
In a second tweet, he wrote: “He is a weak and untruthful slime ball who was a terrible Director of the FBI. His handling of the Crooked Hillary Clinton case will go down as one of the worst “botch jobs” of history. It was my great honor to fire James Comey!”
In a memoir due to hit the bookshelves on Tuesday, Mr Comey said the US president reminded him of a mafia boss who demanded absolute loyalty, saw the entire world against him and lied about everything.
Mr Comey, who was fired by the president in May, also claims that Mr Trump wanted him to investigate allegations that he had paid Russian prostitutes to urinate on a hotel bed to reassure his wife.
He also appears to have likened the president to a “mob boss”.
“This president is unethical, and untethered to truth and institutional values,” he writes, according to excerpts released by The New York Times.
“His leadership is transactional, ego-driven and about personal loyalty.”
