The presidential candidate is not thrilled about facing the Fox correspondent.
Donald Trump is not thrilled about facing Megyn Kelly again when she moderates the Republican primary debate on Thursday night, and has even insinuated he may boycott the event.
"Based on @MegynKelly's conflict of interest and bias she should not be allowed to be a moderator of the next debate," the 69-year-old presidential hopeful tweeted on Saturday.
On Monday, Trump told CNN's Wolf Blitzer that he's not "100 percent" certain he'll show up to the debate because of past interactions with the 45-year-old Fox News anchor. "She better be fair," he insisted. "If I think I'm going to be treated unfairly, I'll do something else."
"I'd like to go to the debate. I've done well in the debates," Trump continued. "Every single poll says I've won every debate."
The aspiring politician was also very blunt about what he thinks of Kelly. "I don't like her. She doesn't treat me fairly. I'm not a big fan of hers at all," he said. Trump also referred back to when Kelly moderated the first GOP debate in August, adding, "I might be the best thing that ever happened to her. Whoever even heard of her before the last debate?"
Meanwhile, Fox News continues to side with Kelly and supports her involvement in the debates. "Sooner or later Donald Trump, even if he’s president, is going to have to learn that he doesn't get to pick the journalists -- we’re very surprised he’s willing to show that much fear about being questioned by Megyn Kelly," a spokesperson told ET. "Megyn Kelly has no conflict of interest. Donald Trump is just trying to build up the audience for Thursday's debate, for which we thank him."
On Tuesday's Good Morning America, Trump seemed to be more open to attending the event in Des Moines, Iowa, but was still not in agreement that Kelly should be moderating. "I think she's not a professional. I don't think she's a very talented person. I don't think she is a good reporter. I think they could do a lot better than that," he said. "You know, I just think they should get competent reporters. They shouldn't use somebody like her."

When asked what the chances are of him showing up for the debate, he added, "Well you could probably make that assumption, but I'm thinking about it."
In a recent issue of Vanity Fair magazine, Kelly claimed that Trump tried to "woo" her prior to the debate in August. "He would send me press clippings about me that he would just sign 'Donald Trump,'" she said. "And he called me from time to time to compliment a segment. I didn't know why he was doing that. And then when he announced that he was running for president, it became more clear."
