The Washington Post reported journalist Bob Woodward's upcoming book, "Fear: Trump in the White House", contains an account of an "expletive-laden altercation" that was part of the Trump White House's overall stormy atmosphere.
Woodward's book also alleges Mr Trump wanted to "f**king kill" Syrian dictator Bashar al-Assad.
Mattis said he'd 'get right on it, ' but ordered limited airstrikes that didn't threaten Assad personally instead.
The statement read: 'The contemptuous words about the President attributed to me in Woodward's book were never uttered by me or in my presence. He's gone off the rails.
Showing her trademark ability to attract attention, former administration official Omarosa Manigault Newman tweeted that clues about the writer's identity were in her recently released tell-all book, offering a page number: 330.
In his interview with The Daily Caller, Trump denied that aides have removed documents from his view, saying "it's just made up" and that "there was nobody taking anything from me".
In the op-ed titled "I Am Part of the Resistance Inside the Trump Administration", the official said he and like-minded colleagues have vowed to thwart parts of the president's agenda and his worst inclinations. I think the president's probably got a lot of respect for the South, I hope so. Someday, when I'm not president, which hopefully will be in about six and a half years, The New York Times, CNN and all of these phony media outlets will be out of business, folks, they'll be out of business, because there'll be nothing to write and there'll be nothing of interest.
Trump has called Sessions "mentally retarded" and a "dumb Southerner", according to Woodward.
While Woodward's is not the first unflattering investigation into Trump's White House, it carries particular weight coming from the man who together with Carl Bernstein authored the Watergate expose that brought down Richard Nixon.
Trump spoke to reporters in the Oval Office Wednesday.
At a National Security Council meeting on January 19, Trump disregarded the significance of the massive USA military presence on the Korean Peninsula, including a special intelligence operation that allows the United States to detect a North Korean missile launch in seven seconds vs. 15 minutes from Alaska, according to Woodward.
"It's really too bad, because nobody told me about it, and I would've loved to have spoken to you".
"I would know. I am one of them", the author wrote. Chief of staff John Kelly is quoted as calling Trump "an idiot" and lamenting, "We're in Crazytown".
A furious Donald Trump called yesterday for the unmasking of an anonymous senior official who wrote in the New York Times that top members of his administration were undermining the president to curb his "misguided impulses".
"The individual behind this piece has chosen to deceive, rather than support, the duly elected president of the United States", White House press secretary Sarah Huckabee Sanders said in a statement Wednesday. Mr. Sessions has been a target of the President's wrath since recusing himself from the Russian Federation investigation.
"This is what we have to deal with", Trump said.
Mattis says in the statement: "While I generally enjoy reading fiction, this is a uniquely Washington brand of literature, and his anonymous sources do not lend credibility".
In the first of two tweets, Trump cited denials by Kelly and other aides in claiming that "their quotes were made up frauds, a con on the public".
Dowd resigned when the president changed his mind and chose to testify.
"The Woodward book is a scam".
