Luigi Mangione revealed in a letter to one of his supporters that he is expanding his music taste while awaiting his trials for the killing of UnitedHealthcare CEO Brian Thompson. "Last week, I downloaded a bunch of Taylor Swift and Charli XCX [songs] onto my tablet," Mangione, 27, wrote to the owner of the X account The Mangione Trial, who shared a photo of the handwritten letter on Tuesday, October 28. "I've never really listened to either of them, but some phony list of my favorite music circulated on social media," he continued.
