Trump is not good for the U.S. economy.

Former White House staffer Omarosa Manigault Newman claims in a new book that there are tapes of President Donald Trump using racial slurs and that she saw him behaving “like a dog off the leash” at numerous events he attended without his wife, first lady Melania Trump.

The accusations are among a long list of scandalous claims contained in her new book, “Unhinged,” set to come out Aug. 14. The Associated Press purchased an early copy of the memoir, which the White House has already slammed as “riddled with lies and false accusations.”

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 allegations, painting the president as scattered, self-absorbed, misogynistic and insecure.

Trump, she said she’d concluded after years of defending him, was a bigot.

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 she had seen him acting inappropriately at numerous events he attended without his wife at his Mar-a-Lago estate in Florida, including birthday parties, fundraisers and golf tournaments.

She also alleges that Trump has exhibited signs of a “mental decline that could not be denied” and says she went as far as printing out a study linking Diet Coke consumption to dementia and strokes and putting it in his briefing stack.
