Luigi Mangione is due in a New York courtroom to face state charges in the murder of UnitedHealthcare CEO Brian Thompson.

The man accused of fatally shooting the CEO of UnitedHealthcare has pleaded not guilty to murder and terror charges in a state case that will run parallel to his federal prosecution.

The high-profile defendant appeared to not have family in the courtroom. But about two dozen women, who waited in line in the frigid cold for public seats in the courtroom gallery, said they were there to support Mangione. Most of the women wore face masks and a few appeared visibly emotional as Mangione entered the courtroom.

A crowd of people, many supporters, flocked to a New York City courthouse, where Luigi Mangione pleaded not guilty to charges of first-degree murder and terrorism in the death of UnitedHealthcare CEO Brian Thompson.

Protesters gathered outside Luigi Mangione’s arraignment at the Manhattan Criminal Courthouse on Monday, December 23, where he faced murder and terrorism charges for allegedly killing United Healthcare CEO Brian Thompson earlier this month.
