In an interview Thursday on CNN, Jennie Willoughby, an ex-wife of Rob Porter, said the former-White House aide had asked her to downplay allegations of abuse she made last year on her Instagram account and in a blog post.

Later in the interview on Thursday, Willoughby expressed concern for the safety of White House communications director Hope Hicks, 29, who has been dating Porter.

"If I'm being frank with you, if he hasn't already been abusive with Hope, he will, and particularly now that he's under a lot of stress and scrutiny," she added. "That's when the behaviors come out. If he hasn't already, he will."
