Former President Donald Trump and the Justice Department are set to face off in a federal appeals court on Monday, as Trump's lawyers argue that a gag order imposed by District Judge Tanya Chutkan violates his constitutional rights. The U.S. Court of Appeals for the D.C. Circuit issued an order pausing the gag order until they could hear arguments from both sides. The outcome of the hearing could have far-reaching implications for Trump's criminal trial and his ability to speak publicly about the case.
