Eric Trump hit Twitter on Monday evening to lash out at George Conway, the conservative attorney who is married to White House counselor Kellyanne Conway.

Trump tweeted, “Of all the ugliness in politics, the utter disrespect George Conway shows toward his wife, her career, place of work, and everything she has fought SO hard to achieve, might top them all. @KellyannePolls is great person and frankly his actions are horrible.”

Conway has been publicly criticizing Trump, his wife’s boss, for months. On Monday, he suggested in a tweet that Trump was tampering with witnesses in special counsel Robert Mueller’s Russia investigation. Conway, a lawyer, has organized a group with the goal of urging fellow conservative lawyers to speak out against the Trump administration’s actions.

His wife Kellyanne, on the other hand, is one of the administration’s most ardent and public supporters, speaking in support of the president’s actions on a weekly basis. Kellyanne regularly makes the rounds on cable news networks defending the president.

Trump has pushed back against George’s criticism, telling reporters that he is only speaking out to “get publicity for himself.”

Kellyanne last month poked fun at the media’s coverage of her husband by making her Twitter bio, “The ‘Kellyanne Conway’ in ‘Kellyanne Conway’s Husband’.”

Twitter had some thoughts:

Perhaps it is KAC who is being disrespectful…Disrespectful to her country and the rule of law, as well as her family…

Oh pu- lease @EricTrump. Stay out of this. Kellyanne lies for your daddy and her husband is calling her on it. I think he should file for divorce. She is a terrible role model for their kids. Almost as bad as your old man.

How does he disrespect his wife? How about you mind your marriage and leave them alone. Is she saying anything??? Why would you?
