After the humiliation of President Barack Obama raking him over the coals for pushing birther conspiracy theories, a top surrogate for Donald Trump said he will have his “ultimate revenge” when all of his critics have to “bow down” to him in the White House.

In a clip previewing an upcoming special from PBS Frontline, published online Thursday, Omarosa Manigault spoke about the abject humiliation Trump felt after Obama did an extended bit about the real estate mogul at the 2011 White House Correspondents Dinner.

“Every critic, every detractor, will have to bow down to president Trump,” Manigault 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.”

Roger Stone, a longtime Trump confidant with loose ties to the campaign, called the 2011 event “the night that [Trump] resolved to run for president.”

The special will air on Tuesday.
