"On the personal attacks?" asked CNN's Brooke Baldwin.

Trump also previously called Clinton an "enabler" of her husband's affairs and accused her of playing the "woman card" to get votes.

Clinton, in an interview with CNN Thursday, refused to respond to Trump's attacks.

"I know that's exactly what he's fishing for, and I'm not going to be responding," she said.
