Donald Trump‘s cuttinginsults about women’s appearanceareextensive and well-documentedbutOmarosa Manigault Newmanmanaged to dig up an untold alleged affront for her new tell-all book,Unhinged, out Tuesday.

Manigault Newman claims that Trump questioned Harriet Tubman’s appearance after the then-White House aide approached him about an Obama-era initiative to put the famous escaped slave and abolitionist on the $20 bill, replacing Andrew Jackson.

Manigault Newman says she wrote a decision memo about the matter and brought it to Trump.

Then, Manigault Newman describes, “He came to the picture of Tubman, the woman who personally brought more than 300 slaves to freedom, risking her own life every time, and said to me, ‘You want to put that face on the twenty-dollar bill?’ ”

And after PEOPLE writer Natasha Stoynoff accused Trump in 2016 of forcing an unwanted kiss on her, he denied the allegations and hinted that he wouldn’t have sexually assaulted Stoynoff because he didn’t find her attractive. “Look at her … I don’t think so,” he said at the time.

In the same chapter of her book, Manigault Newman references 2016 reports that Trump firedKhloe KardashianfromCelebrity Apprenticein 2009 over her weight.

“According to anonymousApprenticestaffer sources, he’d called her a ‘fat piglet’ and bemoaned that they didn’t book ‘the hot one,’ referring to Khloe’s sisterKim Kardashian,” Manigault Newman writes. Trump has never commented on the reports.

But Manigault Newman writes that Trump actually fired Kardashian because she’d been arrested for a DUI in the past. Manigault Newman says that while fellow contestant and Trump friend Dennis Rodman’s drinking was forgiven, “Trump didn’t have the same compassion forKhloe Kardashian… Khloe was taken to task on national television about her arrest and fired.

“I believe sexism played a part, but I also believe Donald was a little jealous of the Kardashians’ fame,” Manigault Newman adds.

As the shocking claims from Manigault Newman’s new book continue to make headlines, the president’s campaign announced on Tuesday that ithas filed for arbitrationagainst the former White House aide for allegedly breaching a 2016 nondisclosure agreement, according to CNN.

Press secretary Sarah Huckabee Sanders also issued a statement saying that the tell-all “is riddled with lies and false accusations,” 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, after not taking her seriously when she had only positive things to say about the President during her time in the administration.”

And within the past 24 hours, President Trump has taken to Twitter in a rage, tweeting that Manigault Newman, who wasfired from her White House positionin December 2017, isa “dog” and has “zero credibility.”
