Omarosa unleashes on Trump in new book

In the book, Manigault Newman, who was a contestant on Trump's "The Apprentice" reality show and later served as a senior adviser to the president, hurls a litany of charges. Trump, she eventually concluded, was "racist."

"I didn't want to believe it," she writes. "I rejected what other people said about him because they didn't know him like I did. I had to go through the pain of witnessing his racism with my own eyes, and hearing it with my own ears, many times, until I couldn't deny it any longer."

She also claims without evidence that tapes exist of the president using the N-word repeatedly on the reality show's set. She acknowledges she had never been able to obtain or hear the tapes.

Manigault Newman also charges that allies of the president tried to buy her silence. When she left the White House, she says she was offered $15,000 a month to serve in a "senior position" on Trump's 2020 re-election campaign. But that offer came along with a stringent non-disclosure agreement as "harsh and restrictive" as she had seen while working in television.

After turning down the job, she said she received a "flurry" of letters from attorneys representing the president telling her to "stay silent about Trump, or else."

Throughout the book, Manigault Newman paints a deeply critical portrait of the president, describing him as a man who "loved conflict, chaos and confusion; he loved seeing people argue or fight." She says he acted inappropriately at numerous events, including birthday parties, fundraisers and golf tournaments in Florida, and writes that being "offensive, inappropriate and off-color is normal for him."

She also alleges that Trump has exhibited signs of a "mental decline that could not be denied."

The White House responded by slamming the book and its author and chastising the press for writing about it.

"Instead of telling the truth about all the good President Trump and his administration are doing to make America safe and prosperous, this book is riddled with lies and false accusations," said White House press secretary Sarah Huckabee Sanders, adding that, "It's sad that a disgruntled former White House employee is trying to profit off these false attacks, and even worse that the media would now give her a platform."
