Omarosa claims in new book Trump 'racist,' used the N-word

Omarosa Manigault Newman, the former "Apprentice" contestant who became a White House aide, claims in her new book that President Donald Trump is a "racist" who used the N-word.

In her upcoming tell-all book entitled "Unhinged," to be published next week and obtained by NBC News directly from the publisher, Manigault Newman alleges that Trump was caught on a microphone saying the N-word "multiple times" during the filming of "The Apprentice," and says there is a tape to prove her allegation.

Manigault Newman wrote that she did not hear Trump use the slur, nor has she listened to the alleged tape. She cites three sources as having told her of the existence of the tape and what Trump says on it.

The Guardian first reported Friday on the quotes in the book and said it had obtained a copy.

In the book, she also describes her "growing realization that Donald Trump was indeed a racist, a bigot and a misogynist," during her time in the White House.

"My certainty about the N-word tape and his frequent uses of that word were the top of a high mountain of truly appalling things I'd experienced with him, during the last two years in particular," Maginault Newman writes.

Maginault Newman, who NBC News reported was dismissed from her White House role, wrote, "It had finally sunk in that the person I'd thought I'd known so well for so long was actually a racist. 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." She says she left the White House job on her own.

Trump hosted the reality television show "The Apprentice" and its spin-off, "The Celebrity Apprentice," both of which aired on NBC, from 2004 to 2015 before running for president. "Celebrity Apprentice" was produced and owned by MGM.

Manigault Newman was a three-time contestant on "The Apprentice" and over time became a close confidant of Trump before supporting him for president and following him to the White House. During his campaign, she was one of his most prominent black supporters.

After her White House stint, Manigualt Newman became a contestant on CBS's "Celebrity Big Brother" and blasted the Trump administration as "so bad."

Deputy Press Secretary Raj Shah pushed back after those comments.

"Omarosa was fired three times on 'The Apprentice' and this was the fourth time we let her go. She had limited contact with the president while here. She has no contact now," Shah said.

Earlier this week, The Daily Beast reported that she also secretly recorded conversations with the president and used that as leverage to get her book deal.

The rumor that Trump used the N-word and other offensive language over the course of filming his TV show has been floated since Trump was a candidate on the campaign trail. Comedian Tom Arnold previously claimed to have knowledge of tapes that purportedly show the president using the disparaging remark and other vulgar language in outtakes of "The Apprentice."

Trump and his campaign were previously roiled by the infamous 2005 "Access Hollywood" tape that was released in October 2016 that heard him bragging in vulgar terms about grabbing and kissing women without their consent.

The White House did not respond to a request for comment.
