nvestigators found two letters on a phone inside the remains of the rented Tesla Cybertruck that active-duty Green Beret Master Sergeant Matthew Alan Livelsberger exploded outside the Las Vegas, Nevada, Trump hotel on New Year’s Day. It appears that Livelsberger wrote them to explain why he was performing what he called “a stunt with fireworks and explosives.” Aside from his personal need to forget about the violence of his military career, he wrote, he wanted to “WAKE UP” servicemembers, veterans, and all Americans.
