NEW YORK — Luigi Mangione will appear in federal court on Friday for a critical hearing aimed at blocking the government from pursuing the death penalty related to the killing of UnitedHealthcare CEO Brian Thompson.

Mangione’s legal team argues that the government has prejudiced the case by turning his arrest into a 'Marvel movie' spectacle and announcing their intent to seek the death penalty before any formal indictment was made. They assert that such actions violate his rights and affect the integrity of the judicial process.

If the argument against pretrial publicity does not succeed, Mangione's lawyers are also seeking to dismiss the charge of murder by firearm, claiming it is legally deficient.

Federal prosecutors contend that the murder charge remains legitimate and assert that intense publicity alone does not constitute a constitutional crisis. They believe potential jurors can be adequately questioned to determine their exposure to case-related information.

Mangione, who has pleaded not guilty to both federal and state murder charges, faces life in prison if convicted. His upcoming hearing follows his first appearance in Manhattan federal court since his arraignment in April.

This hearing is expected to cover not only the defense's arguments to dismiss the death penalty but also their request to exclude specific evidence from the trial. U.S. District Judge Margaret Garnett is also anticipated to set a trial date.

Additionally, Mangione’s team is fighting to exclude evidence from a backpack searched during his arrest, arguing that the police acted without a warrant. This evidence reportedly includes a firearm linked to the murder and notes referencing the intent to 'wack' a health insurance executive.

Thompson was shot and killed in December 2024 as he approached a hotel for a conference. Surveillance revealed the shooting was executed by a masked assailant. Mangione, who is from a wealthy family and holds an Ivy League education, was arrested shortly thereafter.

The case has attracted public attention significantly, with advocates rallying in support of Mangione, often wearing green and carrying signs expressing solidarity.
