WASHINGTON — President Trump’s son Eric put out a tweet Monday night accusing George Conway of “utter disrespect” for his wife, White House aide Kellyanne Conway, apparently because of Conway’s public comments criticizing the administration.

“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,” the president’s middle son said. “@KellyannePolls is great person and frankly his actions are horrible.”

George Conway, a prominent DC lawyer, has been very publicly at odds with his wife’s boss. He recently co-authored an op-ed in the New York Times calling President Trump’s appointment of Matthew Whitaker as acting attorney general unconstitutional and saying it makes a “mockery of our constitution.”

Earlier Monday, Conway accused President Trump of witness tampering — a federal crime. The rebuke came after Trump said on Twitter that his pal Roger Stone has “guts” for not wanting to testify against him.

Conway only responded to Eric Trump by retweeting other users who were critical of Trump’s tweet.

“How does noting that your father engaged in witness tampering today disrespect Kellyanne Conway?” read one of the tweets that Conway retweeted.

Kellyanne Conway, who was Trump’s campaign manager in 2016, has acknowledged her husband’s public attacks on her boss have created problems at home.

“I think it’s disrespectful,” Conway told the Washington Post this summer. “I think it disrespects his wife.”

But George Conway has upped his criticism in recent months. He formed a group of anti-Trump conservative lawyers called Checks and Balances to speak out against Trump’s actions.

Conway has praised his wife for getting Trump elected, but said he can’t keep quiet.

“I don’t think she likes it,” Conway told Yahoo News podcast “Skullduggery” last month. “But I’ve told her, I don’t like the administration, so it’s even.”

Eric Trump is executive vice president of the Trump Organization. His wife, Lara, is very active in President Trump’s 2020 campaign as senior adviser.
