"Look at that face! Would anyone vote for that? Can you imagine that, the face of our next president?" Trump reportedly bellowed while watching his Republican presidential rival on the news. "I mean, she's a woman, and I'm not s'posedta say bad things, but really, folks, come on. Are we serious?”

Fiorina responded to Trump’s remarks late Wednesday on “The Kelly File” on Fox News, saying that “Maybe I'm getting under his skin a little bit because I am climbing in the polls.”

She added that the comments “speak for themselves.”

Trump is no stranger to accusations of sexism.

Most recently, the real estate mogul found himself in a prolonged feud with Fox News host Megyn Kelly after she brought up a few of his past remarks — mainly directed at Rosie O’Donnell — during the first GOP debate.

Trump responded by suggesting Kelly’s line of questioning was the result of menstruation. He later followed that up by retweeting a supporter who referred to Kelly as a "bimbo."
