Some of the key claims from the book 'A Warning' by 'Anonymous' on the Trump administration

WASHINGTON – The 'Anonymous' author purporting to be at the top of the Trump administration is soon releasing a book titled "A Warning," a behind the scenes look into the president of Donald Trump.

The author, identified as "a senior official in the Trump administration," according to news reports, first came to prominence with an anonymous op-ed published in September 2018 in The New York Times that described efforts by the author and other senior officials to protect the country from Trump.

The publisher says the anonymous book author did not take an advance payment for the book, and plans to donate a substantial amount of royalties to "non-profit organizations that focus on government accountability and on supporting those who stand up for the truth in repressive countries around the world," a representative of the author, Matt Latimer, told The Washington Post.

The White House publicly condemned the excerpts of the book that have emerged so far.

"The coward who wrote this book didn’t put their name on it because it is nothing but lies," said White House press secretary Stephanie Grisham.

Here are some of the most explosive claims so far from the book:

Officials thought Pence would support removing Trump

According to an excerpt obtained by HuffPost, senior White House officials did "a back-of-the-envelope tally" of the number of Cabinet members who would support the invocation of the 25th Amendment, which allows for the removal of a president if the majority of the Cabinet and the vice president deem the president unfit for office.

They believed, according to the author, that Pence would support such a move. The discussions allegedly took place after Trump fired FBI Director James Comey in May 2017.

Pence responded to the claim while speaking with reporters in New Hampshire on Thursday, calling the book "appalling."

"I never heard anything in my time as Vice President about the 25th amendment. And why would I?" he said, adding that "Those rumors – I dismissed them several years ago and. I’m happy to dismiss them...today."

'Midnight self-massacre'

The Washington Post reported that the book plans to discuss how White House officials considered a mass resignation last year as part of a "midnight self-massacre," echoing an incident from the Richard Nixon White House when administration officials refused to carry out Nixon's orders were fired en masse.

The mass resignation was considered in order to draw public attention to Trump's conduct, but the officials decided to remain in office rather than destabilize the U.S. government, the official writes.

The author says op-ed was wrong

The author's September 2018 op-ed in the Times claimed there were White House officials standing between Trump and his worst impulses, and that they could keep the president in check. The Post reports the author admitted to being wrong on this point.

"Many Trump appointees have vowed to do what we can to preserve our democratic institutions while thwarting Mr. Trump’s more misguided impulses until he is out of office," the author wrote last year.

"I was wrong about the ‘quiet resistance’ inside the Trump administration," the author writes now. "Unelected bureaucrats and cabinet appointees were never going to steer Donald Trump the right direction in the long run, or refine his malignant management style. He is who he is."

'Like a twelve-year-old in an air traffic control tower'

According to the Post, the author also plans to criticize Trump's character and whether he's fit for office.

The author describes Trump as “like a twelve-year-old in an air traffic control tower, pushing the buttons of government indiscriminately, indifferent to the planes skidding across the runway and the flights frantically diverting away from the airport" in an excerpt provided to the outlet.

In another excerpt, the author writes, "I am not qualified to diagnose the president’s mental acuity" but adds:

"All I can tell you is that normal people who spend any time with Donald Trump are uncomfortable by what they witness. He stumbles, slurs, gets confused, is easily irritated, and has trouble synthesizing information, not occasionally but with regularity. Those who would claim otherwise are lying to themselves or to the country."

Misogynistic and racist comments

The author alleges Trump makes misogynistic and racist comments, based on excerpts provided to the Post.

"I’ve sat and listened in uncomfortable silence as he talks about a woman’s appearance or performance,” the author says in the excerpts. “He comments on makeup. He makes jokes about weight. He critiques clothing. He questions the toughness of women in and around his orbit. He uses words like ‘sweetie’ and ‘honey’ to address accomplished professionals. This is precisely the way a boss shouldn’t act in the work environment."

The author also says Trump attempted to put on a Hispanic accent during a meeting about immigration.

"We get these women coming in with like seven children," Trump said, according to the author. "They are saying, 'Oh, please help! My husband left me!' They are useless. They don’t do anything for our country. At least if they came in with a husband we could put him in the fields to pick corn or something."

Trump fearful of notes

According to the excerpts published by the Post, Trump is particularly fearful of internal White House fights and of notes of meetings.

The Post reports that during one meeting, the president yelled at a staffer who was writing notes.

"What the [expletive] are you doing?" Trump allegedly said. "Are you [expletive] taking notes?" after which the aide closed his notebook.
