NEW YORK — Luigi Mangione was indicted Thursday on a federal murder charge in the killing of UnitedHealthcare CEO Brian Thompson, a required step as prosecutors work to make good on the Trump administration's order to seek the death penalty for what it called a ''premeditated, cold-blooded assassination that shocked America.''
Mangione's indictment, returned by a federal grand jury in Manhattan, includes a charge of murder through use of a firearm, which carries the possibility of the death penalty. The indictment, which mirrors a criminal complaint brought after Mangione's arrest last December, also charges him with stalking and a gun offense.
Mangione's lawyers have argued that U.S. Attorney General Pam Bondi's announcement this month ordering prosecutors to seek the death penalty was a ''political stunt'' that corrupted the grand jury process and deprived him of his constitutional right to due process.
Mangione, a 26-year-old Ivy League graduate from a prominent Maryland real estate family, faces separate federal and state murder charges after authorities say he gunned down Thompson, 50, outside a Manhattan hotel on Dec. 4 as the executive arrived for UnitedHealthcare's annual investor conference.
Surveillance video showed a masked gunman shooting Thompson from behind. Police say the words ''delay,'' ''deny'' and ''depose'' were scrawled on the ammunition, mimicking a phrase commonly used to describe how insurers avoid paying claims.
The killing and ensuing five-day search leading to Mangione's arrest rattled the business community, with some health insurers deleting photos of executives from their websites and switching to online shareholder meetings. At the same time, some health insurance critics have rallied around Mangione as a stand-in for frustrations over coverage denials and hefty medical bills.
Mangione's federal indictment came just before a deadline Friday for prosecutors to either file one or seek a delay. It was not immediately clear when he will be brought to federal court in Manhattan for an arraignment.
A message seeking comment was left for a spokesperson for Mangione's defense team.
