Judge Arthur Engoron rebuked Donald Trump after the former president attacked his clerk in a social media post on Tuesday and forbade the parties from making any future comments about his staff.

“This morning one of the defendants posted on (a) social media account a disparaging untrue and personally identifying post about a member of my staff. Although I have since ordered the post deleted and apparently it was, it was also emailed out to millions of other recipients,” the judge said in court.

“Personal attacks of any member of my court staff are unacceptable, inappropriate and I will not tolerate them,” the judge said.

Trump looked straight ahead at the judge as he issued the order.

The judge then said all parties must not speak publicly about any members of the court staff.

“Consider this statement an order forbidding all parties from posting, emailing or speaking publicly about any members of my staff,” Engoron said. “Failure to abide by this … will result in serious sanctions.”

Trump posted on Truth Social Tuesday attacking Engoron’s clerk, claiming she was a “girlfriend” to Senate Majority Leader Chuck Schumer, a New York Democrat, and showing a picture of the two of them together.

“How disgraceful!” Trump wrote. “This case should be dismissed immediately.”

It was not immediately clear there was a connection between Engoron’s clerk and Schumer beyond taking a photo.

Monday, Trump also went after the clerk in his comments outside the courtroom, though he didn’t mention her by name.

“And this rogue judge, a Trump hater. The only one that hates Trump more is his associate up there,” Trump said. “The person that works with him. She’s screaming into his ear almost every time we ask a question. A disgrace. It’s a disgrace.”
