The judge presiding over the $250 million fraud trial against Donald Trump and his company on Wednesday fined the former president $10,000 for violating an order not to talk about his court staff.

Judge Arthur Engoron handed down the penalty after calling to Trump to testify under oath who he was talking about when he told reporters earlier in the day the person sitting next to the judge was “very partisan.”

Trump said he was referring to the witness testifying for the New York attorney general’s office, Michael Cohen.

Engoron said he found Trump’s testimony “not credible.” He fined Trump for violating the gag order he issued after the former president previously smeared his law clerk on social media. This is the second time Engoron has fined Trump for violating the gag order.
