Rep. Elise Stefanik, R-N.Y., a member of House Republican leadership and an ally of former President Donald Trump, filed an ethics complaint Friday attacking the judge presiding over Trump’s civil fraud trial, the latest salvo in a right-wing war against the case.

Echoing the courtroom rhetoric of Trump’s lawyers, the letter complains that the Democratic judge, Arthur Engoron, has been biased against the former president, who testified this week in New York State Supreme Court. New York Attorney General Letitia James has accused Trump of fraudulent business practices, and in a pretrial ruling Engoron agreed, validating the heart of her case.

The letter, to a judicial conduct commission, is unlikely to have any immediate repercussions on the trial, which will determine the consequences Trump and his company will face as a result of the fraud. But it represents the latest Republican attempt to tar Engoron, and to meddle with James’ case. The judge has placed narrow gag orders on both the former president and his lawyers, but nothing bars Trump’s allies from their criticism.

They have taken up the effort with gusto.

“I filed an official judicial complaint against Judge Arthur Engoron for his inappropriate bias and judicial intemperance in New York’s disgraceful lawsuit against President Donald J. Trump and the Trump Organization,” Stefanik said in a statement Friday.

A spokesperson for the New York court system did not immediately reply to a request for comment on the complaint.

Trump, 77, has repeatedly implored his allies to fight on his behalf. And Stefanik, who has close ties to Trump’s team, has portrayed herself as one of his chief defenders, thrusting herself into the former president’s controversies dating back to the first impeachment he faced while president.

The civil fraud trial, which is separate from the four criminal cases against Trump, began early last month and is at its halfway point. After the former president and his daughter, Ivanka, testified this week, the attorney general’s office rested its case, which accuses Trump and his company of filling annual financial statements with fraudulent asset values in order to receive favorable treatment from banks and insurers. The defense case will start Monday, with Donald Trump Jr. scheduled to return to the stand, and is expected to last into December.

Engoron, 74, has not responded to the attacks outside the courtroom, though at one point this week he lost his temper when a lawyer for Trump, Christopher Kise, suggested, as he has throughout the trial, that the judge had been biased.

“I object now, and I continue to object, to your constant insinuations that I have some sort of double standard here. That is just not true,” the judge said, adding, “I just make the rulings as I see them. You know, like the umpire says, call them as I see them.”
