WASHINGTON – Kellyanne Conway has found herself in the middle of a bizarre fight between her husband, a respected attorney, and the president of the United States. But she seems to have chosen a side.

Conway, a senior aide to Trump and one of his fiercest defenders, stood up for the president in an interview with Politico on Wednesday, telling the publication that Trump has every right to respond to her husband's criticisms.

"You think he shouldn’t respond when somebody, a non-medical professional accuses him of having a mental disorder?" Kellyanne Conway told Politico. "You think he should just take that sitting down?"

Her husband, George Conway, uses his Twitter account to frequently criticize the president about a variety of subjects, including his legal troubles. The criticisms were one-way until this weekend when George Conway questioned Trump's mental stability.

On Wednesday, the president described George Conway as a "husband from hell" and a "whack job," while Conway again questioned the president's mental stability – and at one point called him "nuts."

"George Conway, often referred to as Mr. Kellyanne Conway by those who know him, is VERY jealous of his wife’s success & angry that I, with her help, didn’t give him the job he so desperately wanted," Trump tweeted. "I barely know him but just take a look, a stone cold LOSER & husband from hell!"

Later, as he departed the White House for a trip to Ohio, Trump said he had no regrets about attacking the husband of a top aide.

"He’s a whack job" and is "doing a disservice to a wonderful wife," Trump said. "I call him Mr. Kellyanne Conway. She’s a wonderful woman.”

Conway, who has said that Trump exhibits all the attributes of "narcissistic personality disorder," tweeted in reply to Trump: "You seem determined to prove my point. Good for you!"

He later posted a more direct response: "You. Are. Nuts."

While talking with Politico, Kellyanne Conway said Trump has stayed mum on this subject for months out of respect for her marriage and could have easily fired her if these criticisms became a distraction. She said she and the president have spoken "in passing" about her husband but not in any detail.

"The president is obviously defending me," Conway told Politico. "He could privately say to me, 'Honey you’re a distraction. We love you. You'll always be a part of the family but go be with your kids. They need you. Go make a million dollars an hour. Go do that honey.' It’s the opposite."

Kellyanne Conway added that the feud has not affected her role and pointed to the work she's been doing at the White House while the media has focused on the fight. "Why would it affect my job? Hasn’t everybody tried to push me out already and here I am, stronger than ever," she said.
