New York — Luigi Mangione is due in court Tuesday as his lawyers push to have his state murder charges thrown out in the killing of UnitedHealthcare CEO Brian Thompson. They argue that the New York case and a parallel federal death penalty prosecution amount to double jeopardy.

Also to be decided: a trial date and whether the state case or federal case will go first.

It's Mangione’s first court appearance in the state case since February. The 27-year-old Ivy League graduate has attracted a cult following as a stand-in for frustrations with the health insurance industry. Dozens of his supporters showed up to his last hearing, many wearing the Luigi video game character’s green color as a symbol of solidarity. His April arraignment in the federal case drew a similar outpouring.
