Attorneys for former President Donald Trump have filed a motion for a mistrial in his New York fraud case, alleging bias and unfair treatment by Judge Arthur Engoron and his clerk, Allison Greenfield. Trump's lawyers claim that the court has failed in its responsibility to ensure a fair trial, free from the appearance of impropriety. They argue that Engoron has shown favoritism towards New York Attorney General Letitia James, a Democrat, and that Greenfield, also a Democrat, has been co-judging the case.

The trial, which began on October 2, accuses Trump, his sons, and their company of perpetrating a decade of fraud and benefitting from at least $250 million. The defense argues that Trump is the victim of bias, with Engoron ruling against him and making comments that demonstrate favoritism towards the prosecution.

Engoron has indicated that he will deny the motion, asserting his right to discuss legal issues with his law clerk and defending his communications with her. A spokesperson for the attorney general's office dismissed Trump's claims as an attempt to distract from the allegations of fraud. As the trial progresses, the mistrial motion poses a significant challenge to the proceedings and raises questions about the potential impact of bias on the outcome.
