Book: W. House is ‘crazytown’

President Trump's top aides believe he's an “idiot” with the capacity for understanding of a “fifth or sixth grader” and have gone to great lengths to avert disaster as they struggle with the commander-inchief's impulsive and dangerous personality, according to a book by legendary journalist Bob Woodward.

The veteran Washington Post journalist paints a damning portrait of a West Wing dominated by a man whose closest advisers go out of their way to circumvent him — going so far as to ignore orders, hide information and even swipe papers from his desk.

White House chief of staff John Kelly has flat out called Trump “unhinged” and an “idiot,” according Woodward. Defense Secretary James Mattis describes him as having the understanding of “a fifth or sixth grader.”

Trump's former personal lawyer John Dowd describes the President as “a f---ing liar,” telling Trump he would end up in an “orange jump suit” if he testified to special counsel Robert Mueller.

“He's an idiot. It's pointless to try to convince him of anything. He's gone off the rails. We're in crazytown,” Kelly is quoted as saying at a meeting.

Following a chemical weapons attack on Syrian civilians in April 2017, Trump reportedly told military brass he wanted to assassinate Syrian President Bashar al-Assad.

“Let's f---ing kill him! Let's go in. Let's kill the f---ing lot of them,” Trump told Secretary of Defense James Mattis.

Mattis told the President he would begin working on plans, but then hung up the phone and told an aide, “We're not going to do any of that,” according to Woodward.

The 75-year-old writer offers an unprecedented look at the inner workings of the Trump administration and officials' efforts to deal with a President who has little understanding of world affairs or how government works in the 448-page book, “Fear: Trump in the White House,” which is due out next week .

Trump claimed Woodward's deeply sourced book “could be just made up.”

“It's just another bad book. He's had a lot of credibility problems,” Trump told rightwing outlet Daily Caller in an Oval Office interview without providing any specifics. “It's just nasty stuff.”

Kelly also rebutted claims made about his comments.

“The idea I ever called the President an idiot is not true,” he said.
