Trump said 'who the f*** are you' to Republican congressman who questioned his tweets, book claims

President allegedly dropped f-bomb after he was challenged about his inauguration crowd size claims

Donald Trump fumed “who the f*** are you?” at a Republican congressman who questioned the size of his inauguration crowd, a new book has claimed.

Details of the feisty exchange between the US president and Rep. Bill Posey feature in The Hill to Die On, a new book by Politico reporters Jake Sherman and Anna Palmer.

Mr Posey reportedly asked Mr Trump to stop the “tweets and whining about crowd size”, according to the account, causing the president to fire back with the f-word and repeat his claim to have had the “biggest inauguration” in history.

Extracts of the book, published in the US on Tuesday, have appeared in The Washington Post. The authors conducted a new interview with Mr Trump, in which he claimed to be unconcerned about the Democrats gaining control of the House of Representatives last year.

“Now, I just say, “Hey, folks, let’s go. Give me legislation. Let me see. And if we like it, we’ll work on it”,” he told Mr Sherman and Ms Palmer.

According to the authors, Mr Trump was spotted working out attack lines against Steve Bannon during a briefing on infrastructure.

Seen taking notes in the meeting, he was reportedly found to have scrawled the term “Sloppy Steve” – referring to his former strategist, fired several months earlier.

The book takes a close look at the role of the president’s son-in-law Jared Kushner as it tries to explore the awkward relationship between the Trump administration and Congress.

The authors said the senior advisor to the president appeared as if “he wanted to—and believed he could—single-handedly rewrite Congress’s 200-year-old rules”.

According a review in The Guardian, Mr Kushner told the late senator John McCain “we’re going to change the way the entire government works”.

Mr McCain reportedly responded: “Good luck, son.”

The Washington Post’s Ashley Parker said the book contained “at least one or two nuggets” in every chapter.

The authors claimed some of their sources allowed them to listen in to telephone conversations or conference calls, and also shared meeting notes and transcripts.
