Luigi Mangione pleads not guilty to federal murder charge. What does this mean?

Luigi Mangione pleaded not guilty to the federal charge of murder that carries the death penalty over the killing of UnitedHealthcare CEO Brian Thompson . This means now Mangione will face the trial as the judge told the court that she will hold the next hearing in December to set a date for the trial.

Inside the courtroom, there were some Luigi Mangione supporters before the arraignment began. But they were ushered to an overflow room to make room for journalists covering the trial. Mangione was wearing a beige prison jumpsuit and was shackled at the wrists and ankles as he entered the courtroom.

The judge has ordered all discovery to be produced by the prosecution within 30 days. This will be on May 27. This includes search warrants, social media, and information from the Pennsylvania prosecutors and the Manhattan District Attorney. As a reminder, Mangione was arrested at a McDonald's in Pennsylvania. In court cases, discovery is the formal process where each side gathers and exchanges information and evidence before a trial.
