The man accused of fatally shooting the CEO of UnitedHealthcare pleaded not guilty on Monday to state murder and terror charges while his attorney complained that statements coming from New York's mayor would make it tough to receive a fair trial. Luigi Mangione, 26, was shackled and seated in a Manhattan court when he leaned over to a microphone to enter his plea. The Manhattan district attorney formally charged him last week with multiple counts of murder, including murder as an act of terrorism, in a state case that will run parallel to his federal prosecution. His initial appearance in New York's state trial court was preempted by federal prosecutors bringing their own charges over the shooting. The federal charges could carry the possibility of the death penalty, while the maximum sentence for the state charges is life in prison without parole. Prosecutors have said the two cases will proceed on parallel tracks, with the state charges expected to go to trial first. One of Mangione’s attorneys told a judge that government officials, including New York Mayor Eric Adams, have turned Mangione into a political pawn, robbing him of his rights as a defendant and tainting the jury pool.
