A former federal prosecutor said the Trump administration is using the Luigi Mangione case to “send a message” in the first 100 days through its potential use of the death penalty.
Mangione pleaded not guilty to federal charges of stalking, murder through a firearm, and other firearms offenses during an arraignment hearing on Friday. He’s accused of killing UnitedHealthcare CEO Brian Thompson in December outside a Hilton hotel where an annual shareholder meeting was scheduled to take place.
Federal prosecutors indicated in a Thursday night filing that they intend to seek the death penalty against Mangione. Prosecutors argued that Mangione “intentionally” targeted and killed Thompson because he was the CEO of a major health insurance company.
“Mangione elected to murder Thompson under these circumstances to amplify an ideological message, maximize the visibility and impact of the victim’s murder, and to provoke broad-based resistance to the victim’s industry,” prosecutors wrote.

Attorney General Pam Bondi announced on April 1 she would ask a jury to seek the death penalty.
“After careful consideration, I have directed federal prosecutors to seek the death penalty in this case as we carry out President [Donald] Trump’s agenda to stop violent crime and Make America Safe Again,” Bondi said.
James Trusty, former Assistant United States Attorney at the U.S. Attorney’s Office, District of Maryland, told Fox News Digital why he thinks the Trump administration is seeking the death penalty.
“I think it’s a high-profile case and they’re wanting to send a message that the death penalty is back on the table for federal prosecutions,” Trusty said.
The former federal prosecutor also said there might have been “moral levers” pushed within the Department of Justice upon seeing Mangione be hailed as a hero by some after the alleged murder of Thompson.
“This whole idea that Luigi Mangione is some sort of ‘folk hero’ for executing a father of two and, you know, sneaking up from behind and shooting him. That may just be the type of thing that kind of pushes some moral levers within the Department of Justice, where it’s easier for them to be comfortable pursuing a death penalty,” Trusty said.

Trusty also said prosecutors are going to need to “weigh” the possibility of jury nullification when thinking about “how aggressively they’re gonna pursue this.”
Trump ended former President Joe Biden’s moratorium on federal executions when he took office in January. Biden previously paused all federal executions in cases not involving mass murders or terrorism.

Before leaving office in January, Biden commuted the death sentences of 37 out of 40 inmates who will now face life in prison without the possibility of parole.
Trump indicated in December that he would direct the Department of Justice to resume using the death penalty.
“As soon as I am inaugurated, I will direct the Justice Department to vigorously pursue the death penalty to protect American families and children from violent rapists, murderers and monsters,” Trump said at the time.
Outside the courthouse during Friday’s arraignment, a large group of Mangione supporters gathered and held signs that read “No death for Luigi Mangione,” “Free Luigi” and “Luigi before fascists.”

One person, however, showed his distaste toward Mangione by bringing an electric chair with a skeleton, depicted as Mangione, sitting on it. The man who brought the chair held a sign reading “F–k Luigi.”
