Former President Trump’s legal team is back in court on Monday after a Friday hearing in which both sides argued the legality of Special Counsel Jack Smith’s appointment in the classified document case against the former president.

The hearing continues Monday when the two sides again discuss matters related to Smith’s appointment as well as a limited gag order that prosecutors have requested to bar Trump from comments they fear could endanger the safety of FBI agents and other law enforcement officials involved in the case.

Trump’s lawyers have said any speech restrictions would infringe on his free speech rights. Cannon initially rejected the prosecution’s request on technical grounds, saying Smith’s team had not sufficiently conferred with defense lawyers before seeking the restrictions. Prosecutors subsequently renewed the request.

U.S. District Judge Aileen Cannon heard hours of arguments Friday from lawyers for both sides, with Trump attorney Emil Bove asserting that the Justice Department risked creating a “shadow government” through the appointment of special counsels to prosecute select criminal cases.
