'This is Treason': Read the most dramatic quotes from Bob Woodward's new tell-all book about Trump's White House

September 04, 2018 "Information Clearing House" -  A new tell-all book authored by famed Watergate journalist Bob Woodward, reported Tuesday by The Washington Post, shows President Donald Trump viciously attacking the top officials in his own administration. But it also shows several of Trump's underlings aren't too fond of their boss, either.

"Fear: Trump in the White House," which is reportedly largely based on interviews with sources inside the Trump administration, finds Trump insulting his Cabinet members and highest-ranking national security officials, including Attorney General Jeff Sessions, chief of staff John Kelly, former national security advisor H.R. McMaster and many others.

The White House did not immediately respond to CNBC's requests for comment on the Post's article about Woodward's book. "Fear" is due to be published Sept. 11.

But Trump also criticized Sessions for his Southern accent, reportedly mocking it and saying of his own administration's attorney general: "This guy is mentally retarded. He's this dumb Southerner … He couldn't even be a one-person country lawyer down in Alabama."

Trump also called Sessions a "traitor" for recusing himself from the Russia probe, which is led by special counsel Robert Mueller, and putting Deputy Attorney General Rod Rosenstein in charge of oversight.

Kelly denied the report at the time, calling it "total B.S." But Woodward's book repeats the claim, according to the Post.

In a small meeting, Kelly reportedly said of Trump: "He's an idiot. It's pointless to try to convince him of anything. He's gone off the rails. We're in Crazytown. I don't even know why any of us are here. This is the worst job I've ever had."

"This is treason," Trump said, according to the report about Woodward's book. Cohn stayed on until March, resigning shortly after Trump said the U.S. would impose tariffs on imports of steel and aluminum from a variety of countries.

Kelly then reportedly confided to Cohn: "I would have taken that resignation letter and shoved it up his ass six different times."

Defense Secretary James Mattis responded: "We're doing this in order to prevent World War III."

Woodward reportedly said Mattis was "particularly exasperated and alarmed" after the meeting, "telling close associates that the president acted like — and had the understanding of — 'a fifth- or sixth-grader.'"
