President Donald Trump casually dropped the N-word during his time as the star of “The Apprentice” and regularly uses racist epithets in the White House, according to reality TV star Omarosa Manigault Newman.

Manigault Newman is releasing a book this week containing an “explosive” account of her tenure in the Trump administration and detailing her story of the reasons behind her exit.

The Guardian reported that the tell-all memoir — dubbed “Unhinged: An Insider’s Account of the Trump White House” — repeats the claim that a tape exists featuring Trump using the N-word during outtakes for his NBC reality show, on which Manigault Newman was a contestant.

“(T)hree sources in three separate conversations had described the contents of this tape,” she writes. “They all told me that President Trump hadn’t just dropped a single N-word bomb. He’d said it multiple times throughout the show’s taping during off-camera outtakes, particularly during the first season of ‘The Apprentice.’? ”

Rumors of the tape have circulated since before the 2016 election, and questions about the recording were raised after the release of the “Access Hollywood” recording featuring Trump saying his celebrity status entitled him to assault women and “grab ’em by the p ---- y.”

Manigault Newman appeared on the show’s first season and returned twice more before joining Trump in Washington as director of communications for the White House office of public liaison. She claims that during her time in the administration she witnessed Trump using racist language.

Manigault Newman mentions that Trump would turn to hateful phrases when discussing White House counselor Kellyanne Conway’s husband, George, who is half Filipino. “Would you look at this George Conway article?” Trump said during one exchange, according to the book. “F--ing FLIP! Disloyal! F--ing Goo-goo.” Both terms are considered racist.

Conway, who has tweeted criticisms of the president, rejected Manigault Newman’s claim. “The allegation is not credible, and indeed is ridiculous,” he tweeted Friday. “It’s absurd all around.”

Manigault Newman claims the realization that Trump was a bigot helped her decide to jump ship in December.

On Saturday, Trump called her “a lowlife.”
