The one-sided feud between G.O.P. front-runner Donald Trump and Fox News anchor Megyn Kelly rages on.

Trump has had a sharp tongue and trigger fingers ready to retweet critical, sometimes crude comments about Kelly since the first Republican debate this summer, when she asked the candidate about his attitude toward women. Onstage, Trump at first tried to laugh her question off, and then complained about the way she treated him. In the nights and weeks that followed, Trump claimed Kelly had “blood coming out of her eyes, blood coming out of her wherever,” and referred to her as a “lightweight” on Twitter. Kelly, meanwhile, only responded at the time by saying she would continue to do her job.

But his ire was sparked again this week, this time by Kelly’s cover story in the February issue of Vanity Fair. In discussing the debate tiff and her history with the candidate, Kelly described how Trump would occasionally call her to compliment her show and send her press clippings about himself. “I can’t be wooed,” she explained to Vanity Fair contributing editor Evgenia Peretz. “I was never going to love him, and I was never going to hate him.”

Trump, unsurprisingly, did not take kindly to this. The candidate responded on Twitter Wednesday, tweeting that Kelly was “so average in every way.”

It’s a sentiment he recently repeated to The Hill, saying, “the last person in the world I would try to woo is Megyn Kelly.”

The two will meet again later this month in another Fox News debate moderated by Kelly, just before the Iowa caucus. Let’s just say there will be blood.
