(CBrief) – Republican Utah Sen. Mitt Romney has responded to GOP Georgia Rep. Marjorie Taylor Greene’s idea for a national divorce and he is not a fan.

“I think Abraham Lincoln dealt with that kind of insanity,” he said to The Salt Lake Tribune on Tuesday. “We’re not going to divide the country. It’s united we stand and divided we fall. There are some people in my party and the other party that say things to try and get a headline and get people to send them money. And that happens to be in today’s ‘loony left,’ or I should say ‘loony right.’”

But the Georgia firebrand representative hit back at Romney when she spoke to the Washington Examiner.

“Mitt Romney is so bad I couldn’t even vote for him for president against Barack Obama,” she said.

This week Rep. Greene said she was attacked while dining at a restaurant.

“I was attacked in a restaurant tonight by an insane women and screamed at by her adult son. They had no respect for the restaurant or the staff or the other people dining or people like me who simply have different political views. They are self righteous, insane, and completely out of control. I was sitting at my table, working with my staff, and never even noticed these people until they turned into demons. People used to respect others even if they had different views. But not anymore. Our country is gone,” she said on Twitter.
