A New York judge has imposed a gag order on Donald Trump, limiting the former president from making statements about potential witnesses in the criminal trial relating to hush money payments scheduled to begin next month.

Judge Juan Merchan also said that Trump can’t make statements about attorneys, court staff or the family members of prosecutors or lawyers intended to interfere with the case. Trump is also barred from making statements about any potential or actual juror.

The former president, Merchan wrote, has a history of making “threatening, inflammatory, denigrating” statements against people at all levels of the justice system, including jurors.
