Donations to the legal defense fund for Luigi Mangione, the man accused of fatally shooting UnitedHealthcare CEO Brian Thompson in December, have surpassed $1 million, organizers announced Tuesday.

The campaign, hosted on GiveSendGo, has received more than $1.03 million in contributions. Organizers framed the milestone as both financial support for Mangione’s legal battle and a symbolic protest against what they call “our lethal for-profit healthcare system and the indefensible economic and political order that has imposed it upon us.”

“This milestone was reached because of the continued resonance of Mr. Mangione’s story,” said Sam Beard, spokesperson for the December 4 Legal Committee.

Over 28,000 individuals have donated to the fundraiser so far, with a median contribution of $20. Organizers aim to reach $1.5 million to help cover costs related to three ongoing criminal cases in New York and Pennsylvania.

Mangione, who turned 27 on Tuesday, faces multiple state and federal charges in New York related to the December 4 shooting of Thompson outside a midtown Manhattan hotel. At the time, Thompson was en route to speak at UnitedHealth Group’s investor conference at the New York Hilton Midtown.

After a five-day search, Mangione was arrested at a McDonald’s in Altoona, Pennsylvania. He is also facing state charges in Pennsylvania for allegedly possessing an unlicensed firearm, forgery, and using false identification.

If convicted on federal charges, Mangione could face the death penalty.

Thompson’s death prompted a surge of online support for his alleged killer, sparking debate before Mangione’s capture.

Representatives from the Manhattan District Attorney’s Office and the U.S. Attorney for the Southern District of New York declined to comment Tuesday.
