"Unhinged: An Insider's Account of the Trump White House" reportedly contains a number of bombshell allegations against Trump from Manigault Newman's time in the West Wing, though some of them have been contradicted or widely discredited.
She also alleges that Trump has exhibited signs of a "mental decline that could not be denied" and says she even printed a study linking Diet Coke consumption to dementia and strokes and left it on his desk, according to a copy of the book obtained by the Associated Press.
Trump called Manigault Newman "wonderful", "a very nice person" and a "very, very fine person" when she joined him on the campaign trail in 2016.More news: Security alert at Seattle's SeaTac airport after plane took off without permission

According to her, Trump suggested he was sworn in over the book instead of the Bible.
The Guardian newspaper reports that in the memoir, Manigault Newman labels Trump a "racist" and claims she's been told there are tapes of him using the N-word repeatedly while filming "The Apprentice" reality series on which she appeared.
Former White House staffer Omarosa Manigault Newman says in a new book that she didn't want to believe President Donald Trump was racist but saw it with her own eyes. "Yeah. The Art of the Deal is a bestseller!"
And Sanders is correct - both Manigault Newman and Trump once had a close relationship after she became a star contestant and popular villain on his hit reality TV show, "The Apprentice". "Using the N-word was not just the way he talks but, more disturbing, it was how he thought of me and African Americans as a whole". While she doesn't provide direct evidence, she cites three unnamed sources who attest to the existence of the tape.
