Luigi Mangione winks to gallery as feds seek death penalty in CEO slaying
Luigi Mangione was arraigned Friday on federal charges in the December killing of UnitedHealthcare CEO Brian Thompson — a deliberate attack carried out to “amplify an ideological message” and stoke “broad-based resistance” to the health insurance industry, federal prosecutors said in a court filing.
Mangione, 26, appeared in Manhattan federal court a week after a grand jury indicted him on four countsincluding murder through the use of a firearm, which carries a maximum penalty of death.
Mangione, who pleaded not guilty, appeared calm throughout the 35-minute hearing as he conferred with his attorneys. Unlike past court appearances, he was dressed head-to-toe in a tan prison uniform rather than civilian clothes. He was not handcuffed and appeared to have had a recent haircut.
At one point toward the conclusion of the hearing, Mangione appeared to wink at someone seated in the packed gallery. It was not immediately clear who he was interacting with.
His defense team, led by Karen Friedman Agnifilo, alleged her client is enduring an “unprecedented dual prosecution,” referring to state and federal charges Mangione faces in New York. She insisted the overlapping cases created constitutional and logistical issues for the accused murderer.
Friedman Agnifilo also told District Judge Margaret Garnett that prosecutors in Manhattan had inadvertently listened to a telephone call from jail between Mangione and his legal team. She described the incident as “eavesdropping,” though she said it appeared to be unintentional and limited to one person.
“This is the very first time we’ve heard of this situation,” federal prosecutor Dominic Gentile told Judge Garnett.

Judge orders new motion on death penalty in Mangione case
The death penalty remained a central topic in court today, as Judge Margaret Garnett directed defense attorney Karen Friedman Agnifilo to submit a new motion. Agnifilo’s initial request to block the government from seeking the death penalty was filed before Luigi Mangione’s formal indictment and before prosecutors officially notified the court of their intent to pursue capital punishment. The judge set a deadline of June 27 for the new motion to be submitted.
Additionally, the judge instructed prosecutors to remind Attorney General Pam Bondi and other government officials of the impact that public statements can have on jury selection and the fairness of the trial. The potential for the death penalty is a key reason why the defense wants Mangione’s federal trial to proceed before his state trial.

Mangione’s lawyers raise concerns over dual prosecutions and death penalty politics
Luigi Mangione appeared calm in court today, dressed in a tan prison jumpsuit, as his high-profile murder case moved forward. He occasionally glanced around the packed courtroom or passed notes to his attorneys.
His defense team, led by Karen Friedman Agnifilo, again criticized what they called an “unprecedented dual prosecution,” referring to both state and federal charges Mangione faces in New York. She argued the overlapping cases were creating constitutional and logistical problems.
The case has drawn political attention since Attorney General Pam Bondi announced the Justice Department would seek the death penalty, framing it as part of President Trump’s broader crackdown on violent crime. In court, the judge cautioned prosecutors to remind Bondi and others that public statements could affect the jury selection process.

Mangione’s lawyer says jail calls with legal team were overheard
During Friday’s court hearing, Luigi Mangione’s attorney, Karen Friedman Agnifilo, told the judge that state prosecutors had inadvertently listened to a jail call between Mangione and his legal team. She described the incident as “eavesdropping,” though she said it appeared to be unintentional and limited to one person.
Federal prosecutor Dominic Gentile said, per Newsweek reporter Joshua Rhett Miller, “This is the very first we’ve heard of this situation.”
In response, the judge ordered the government to submit a letter within seven days confirming that Mangione will have secure, private phone access to his lawyers.

Mangione’s lawyers request federal murder trial be held first
Mangione is facing two separate murder cases: one at the state level and one at the federal level.
He has pleaded not guilty in both, meaning two trials are expected.
Although it had previously been agreed that the state case would proceed first, Mangione’s defense team has now asked the court to prioritize the federal case.
That trial carries the possibility of a death sentence, and his lawyers say it should be addressed first.

Critic slams call for death penalty in Luigi Mangione case
Attorney General Pam Bondi has directed federal prosecutors to pursue the death penalty against Luigi Mangione, the man accused of killing UnitedHealthcare CEO Brian Thompson in what authorities are calling “murder as an act of terrorism.”
In response, Abraham Bonowitz, executive director of Death Penalty Action, issued a sharp rebuke Friday, calling the move a “hypocritical political stunt.”
Bonowitz argued in a statement sent to Newsweek that capital punishment fails to bring true justice or enhance public safety, referencing the life sentence given to the perpetrator of the El Paso Walmart mass shooting, who was not sentenced to death despite targeting victims based on race.
“Brian Thompson’s life did not matter more than the lives of regular people who were simply out shopping while Brown,” Bonowitz said, urging the Justice Department to reconsider and seek an alternative punishment if Mangione is convicted.
Mangione’s trial has not yet begun, and he has pleaded not guilty in a separate state case related to the December 2024 shooting.

How the death penalty works in the United States
The death penalty is reserved for the most serious crimessuch as murder, treason, or the killing or kidnapping of top U.S. officials. Unlike other punishments, a jury, not just a judge, must decide whether to impose it.
Though many states have abolished or stopped using capital punishment, the federal government still retains the option. The Supreme Court has ruled that executing individuals who were under 18 at the time of the crime or who are intellectually disabled violates the Constitution’s ban on cruel and unusual punishment.

Luigi Mangione donations surge to nearly $1 million
Mangione has seen his legal defense fund surge with two large anonymous donations. As his case moves toward a potential federal death penalty trial, the GiveSendGo campaign has now raised over $948,679.
The recent donations, including $23,000 from one anonymous donor who expressed opposition to the political exploitation of the case, reflect growing unease among supporters about the perceived political overtones of the trial. The legal funds will cover costs related to the three ongoing criminal proceedings against Mangione.
“An ocean of love support you, Luigi,” one anonymous donor who gave $50 wrote early Friday.
“You deserve more than a fair trial,” wrote another supporter, Mark Rosario, who donated $56 and is the name on the fake New Jersey ID that Mangione had on him at the time of his arrest in Altoona. “You deserve freedom, dignity, and a future. We see you, we believe in you, and we’re not going anywhere. The fight isn’t over. It’s only begun.”
The case has drawn significant public attention, especially following U.S. Attorney General Pam Bondi’s announcement that federal prosecutors would seek the death penalty, framing the case as part of a broader effort to combat violent crime.

Man arrested near UnitedHealthcare headquarters in Minnesota after threatening violence
A man was arrested near UnitedHealthcare’s headquarters in Minnetonka, Minnesota, after allegedly threatening violence, authorities said on April 14. The incident occurred at around 11 a.m. when the man was spotted in a parking lot outside the corporate campus. The individual contacted the FBI’s Minneapolis field office, and an FBI negotiator made contact by phone.
After about an hour of steady communication, police and the FBI convinced the man to surrender peacefully, with no threat to the public. The man, who had prior interactions with local police, was found at a security checkpoint where he wasn’t authorized to be.
While the investigation is still in its early stages, officials stated there was no indication the man had specific grievances against UnitedHealthcare. The incident is not linked to the December killing of the company’s CEO, Brian Thompson, who was shot outside a New York hotel by Luigi Mangione. Mangione faces state and federal charges, including murder, and prosecutors are seeking the death penalty.
