The four remaining GOP contenders for the White House are set to face off in another debate likely to be filled with dramatic attacks.

At 9 p.m. EST, Donald Trump, Marco Rubio, Ted Cruz, and John Kasich will take the stage for the 11th debate of the cycle.

The Fox News-hosted event comes a month after Trump boycottedthe previous Fox debate after complaining that moderator Megyn Kelly would be unfair to him.

Trump has fiercely attacked Kelly since the first Fox-hosted debate last summer, during which shefamously confronted him over disparaging comments he's made about women.

In a Thursday-morning interview on "Good Morning America,"Trump said he was "absolutely ready" to face Kelly again.

And in an interview with Business Insider earlier this week, another Fox moderator, Bret Baier, said his team believed that the whole brouhaha was "water under the bridge," and it would not be a debate topic unless other candidates brought it up.

The Thursday-night debate will also feature tensions between Sens. Cruz and Rubio, who have both implicitly called for the other to drop out in order to help form a coalition against Trump. There is even increased speculation about about an 11th-hour attempt to stop Trump at the Republican convention this summer.

10:02 p.m. EST — Kelly played a montage of Trump changing his positions past on issues like Syrian refugees, and whether American troops should remain on the ground in Afghanistan. Trump defended himself by saying that leaders often change their minds.

9:41 p.m. EST — Trump told Kelly that he believed increasing the number of visas for high-skilled foreign workers.

"We need people to get along. We need to get things done."

9:21 p.m. EST — Rubio slammed Trump for resorting to ad hominem attacks instead of addressing questions about policy.

"You see what happens again when you ask challenge him on a policy issue?" Rubio said. "You ask him about economic issues, and he the first thing he does is launch into this thing about 'little Marco.'"

9:02 p.m. EST — Co-moderator Chris Wallace began the debate by asking Trump about former Massachusetts Gov. Mitt Romney's recent criticisms of the former reality-television star.
