"Every critic, every detractor, will have to bow down to President Trump," says Manigault, the director of African-American outreach for the GOP nominee's campaign, in a Frontline special set to air Tuesday on PBS. "It's everyone who's ever doubted Donald, who ever disagreed, who ever challenged him. It is the ultimate revenge to become the most powerful man in the universe."
Manigault, the woman cast as the villain on Trump's reality show, The Apprentice, suggests in the interview that Trump first decided to run for president on the night of the 2011 White House Correspondents Dinner, where he and his birther crusade were mercilessly mocked by Obama.

"It just kept going and going and he just kept hammering him," Manigault said. "And I thought, 'Ohhhh, Barack Obama is starting something that I don't know if he'll be able to finish.' "
Adds Trump political adviser Roger Stone, "I think that is the night that he resolved to run for president. I think that he is kind of motivated by it. Maybe I'll just run, maybe I'll show them all."
For his part, Trump has denied the night had any real impact on him. "The next day [the press] said, 'Donald Trump had a miserable time, he felt humiliated,' " Trump told CNN's Chris Cuomo this past May. "I didn't feel humiliated, I had a great time."
