Donald Trump says he wasn't referring to menstruation when he made comments about Megyn Kelly and her blood following during Thursday's Republican debate. Trump made his comments on Friday, saying that Fox News anchor Megyn Kelly had "blood coming out of her eyes, blood coming out of her wherever." Trump did not take the chance to apologize when offered on Sunday, according to The Guardian.

"I don't want to say that. I apologize when I'm wrong," he said.

Other Republican presidential nominees believe Trump was wrong for what he said, though.

"Women understood that comment. And yes, it is offensive," Carly Fiorina said.

Other Republicans are also distancing themselves from Trump in the wake of the controversy. He's been disinvited from the Red State conference in Atlanta and has faced considerable backlash in the press and on social media. One of his campaign advisers quit over the weekend, though the Trump camp says he was fired.

"[Kelly] should really be apologizing to me, to tell the truth," Trump said on MSNBC's "Morning Joe," according to E! Online.

Kelly was one of three moderators at Fox's Republican Debate, and the only woman on the panel.

"It's okay. I'm a big girl, I can take it," Kelly said of Trump, according to The New York Daily News.
