U.S. Attorney General Pam Bondi said Tuesday she has directed federal prosecutors to seek the death penalty against Luigi Mangione, the man accused of gunning down UnitedHealthcare CEO Brian Thompson outside a New York City hotel on Dec. 4.

Mangione, 26, faces separate federal and state murder charges for the killing, which rattled the business community while also galvanizing health insurance critics. The federal charges include murder through use of a firearm, which carries the possibility of the death penalty. The state charges carry a maximum punishment of life in prison.
