Donald Trump took his attacks on Fox News anchor Megyn Kelly “to the next level on Friday night, apparently insinuating that the moderator had been menstruating when she questioned him during Thursday’s first Republican debate,” Politico reports.

Said Trump: “You could see there was blood coming out of her eyes, blood coming out of her — wherever.”

“Unlike undocumented immigrants, John McCain or Rosie O’Donnell, the Fox News anchor enjoys a huge following among the network’s viewers, who happen to make up the core of the Republican primary electorate. So picking a fight with Kelly — as Trump did when he chided her during a tough debate question about insults he’s lobbed at women, dissed her in the spin room, and tweeted his complaints about her — carries risks that Trump’s other feuds do not.”
