Luigi Mangione, the man accused of gunning down the CEO of UnitedHealthcare in New York City, is breaking his silence on the outpouring of support since his arrest in Pennsylvania on murder and terrorism charges last month.

Mangione is currently awaiting trial at the Metropolitan Detention Center in Brooklyn.

“I am overwhelmed by — and grateful for — everyone who has written me to share their stories and express their support,” Mangione wrote Friday in a statement published on his website, which was launched by the 26-year-old’s legal defense team in New York.

“Powerfully, this support has transcended political, racial, and even class divisions, as mail has flooded MDC from across the country, and around the globe,” he continued. “While it is impossible for me to reply to most letters, please know that I read every one that I receive.”

The University of Pennsylvania graduate went on to thank “everyone who took the time to write” and said he looked forward to reading more messages.

Late last year, President Donald Trump called the deluge of support for Mangione from Americans frustrated with the state of U.S. healthcare a “sickness.”

“It’s really terrible that some people seem to admire him, like him,” Trump said in December. “And I was happy to see that it wasn’t specific to this gentleman that was killed. It’s just an overall sickness as opposed to a specific sickness. It was cold-blooded.”

UHC CEO Brian Thompson was fatally shot in the early morning on Dec. 4 outside a Manhattan hotel he was staying at for an investors’ meeting. Mangione, who was arrested five days later in Altoona, Pennsylvania, in connection to the killing, pleaded not guilty before Christmas.

While officials in both Pennsylvania and New York decried the killing — Pennsylvania Gov. Josh Shapiro said Mangione is “no hero” — a groundswell of sympathy for Mangione sprung up rapidly on social media.

During then-ongoing wildfires in Southern California last month, comedian Bill Burr slammed the insurance industry on “Jimmy Kimmel Live,” and touched on the Mangione case by jokingly declaring, “Free Luigi!” and mocking the media coverage of his case.

Friday was the first time Mangione has issued a statement after his arrest. His family previously said they are “devastated” by the accusations against Mangione, who was allegedly arrested with a three-page manifesto authorities claim exposed his “ill will.”

Mangione is charged with one count of first-degree murder and two counts of second-degree murder, one of which was charged as an act of terrorism, as well as multiple weapons charges. He is next scheduled to appear in court Feb. 21.
