Luigi Mangione Pleads Not Guilty To Federal Murder Charge In Killing Of UnitedHealthcare’s CEO

13 hours ago Luigi Mangione has pleaded not guilty to a federal murder charge in the killing of UnitedHealthcare CEO Brian Thompson, as prosecutors formally declared their intent to seek the death penalty against him. Mangione, 26, stood with his lawyers as he entered the plea Friday, leaning forward toward a microphone as he addressed U.S. District Judge Margaret Garnett. Asked how he wished to plead, Mangione said simply, “not guilty.” Mangione’s arraignment attracted several dozen people to the federal courthouse in Manhattan, including former Army intelligence analyst Chelsea Manning, who served about seven years in prison for stealing classified diplomatic cables.
