Speaking at a press conference before a rally in Marshalltown, Iowa, Donald Trump continued to turn the screws on Roger Ailes, threatening that he “probably” won’t participate in the Fox News-hosted debate on Thursday. Trump’s campaign manager, meanwhile, told the Washington Post’s Philip Rucker that the candidate was “definitely not” participating in the debate. “His word is his bond.”

Trump’s complaint is primarily with Megyn Kelly, who he said treated him unfairly during the first Fox News debate. “Fox is playing games,” Trump said, according to The Hill. “Fox is going to make a fortune. I told Fox they should give their money to the Wounded Warriors.”

“I’m not a fan of Megyn Kelly she’s a third rate reporter. I think she frankly is not good at what she does and I think they could do a lot better than Megyn Kelly. And so I’m going to be making a decision with Fox but I probably won’t bother doing the debate.”
