Famed Watergate journalist Bob Woodward, whose new book paints a picture of turmoil, chaos and infighting in the Trump administration, warned that “people better wake up” to the president’s behavior in the White House.

“People better wake up to what’s going on,” Woodward told “CBS Sunday Morning.” “You look at the operation of this White House and you have to say, ‘Let’s hope to God we don’t have a crisis.'”

Woodward in his book, “Fear: Trump in the White House,” said that administration officials fearing Trump’s impulsive nature have even taken to stealing documents from his desk to avert a full-blown crisis.

“People who work for him are worried … that he will sign things or give orders that threaten the national security or the financial security of the country, or of the world,” Woodward said.

In excerpts of the book – his 19th – that hits bookstores on Tuesday, Woodward writes that former Chief Economic Adviser Gary Cohn and onetime White House Staff Secretary Rob Porter intentionally worked to foil Trump’s actions.

The longtime Washington Post reporter said Cohn removed documents ending a trade agreement with South Korea from the president’s Oval Office desk so

Trump couldn’t sign them because “this would endanger the country.”

He said if the papers were out of sight, they were out of Trump’s mind.

“[Trump] doesn’t remember. If it’s not on his desk, if it’s not immediately available for action, it goes away,” Woodward told CBS.

Woodward, whose reporting with Carl Bernstein blew the lid off President Nixon’s Watergate scandal, said the Trump White House is the ninth he’s covered – and he’s never seen it so bad.

“In the eight others,” he said, “I never heard of people on the staff in the White House engaging in that kind of extreme action.”

The White House has dismissed the book as full of “fabricated” stories, and Trump said it has “credibility problems.”

But Woodward defended the reporting behind “Fear” as “meticulous and careful” and noted that he had multiple sources for every claim.

“Multiple interviews with key witnesses. One person I interviewed nine times, and the transcripts of those conversations are 700 or 800 pages,” he said.

Asked how many people he interviewed, Woodward said, “Over a hundred. I would say that maybe half of those are key people.”

The New York Times published an op-ed written by an anonymous “senior administration official” last week that echoes many of the claims Woodward makes in his book, but he said he has “no idea” who the author is.
