“Every critic, every detractor, will have to bow down to President TrumpDonald John TrumpAmash responds to 'Send her back' chants at Trump rally: 'This is how history's worst episodes begin' McConnell: Trump 'on to something' with attacks on Dem congresswomen Trump blasts 'corrupt' Puerto Rico's leaders amid political crisis MORE,” she said. "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, Trump’s director of African-American outreach, made the prediction in an interview for a PBS “Frontline" special on the 2011 White House Correspondents’ Dinner.

It has been reported that President Obama’s mocking of Trump over his "birther" stance during the dinner prompted the real estate magnate to run.

Recalling the dinner and watching Trump get “hammered” by Obama, Manigault told PBS she thought, "Oh, Barack ObamaBarack Hussein ObamaTrump averages highest approval rating of his presidency in second quarter: Gallup The Hill's Morning Report - Trump seizes House impeachment vote to rally GOP Democrats warm to idea of studying reparations MORE is starting something that I don’t know if he’ll be able to finish.”

"Inside the Night President Obama Took On Donald Trump,” part of “Frontline’s” ongoing political series “The Choice,” will air Tuesday at 9 p.m. EDT on PBS.
