Michael Marx, a Texas resident, was indicted in U.S. District Court on charges including assaulting federal officers with a dangerous weapon and using a firearm during a crime of violence. The charges stem from an incident on May 4, 2026, near 15th Street and Madison Drive NW in Washington, D.C., during which a Secret Service agent observed Marx concealing a firearm and a bystander was struck. U.S. Attorney Jeanine Pirro stated that prosecutors will seek to prove Marx carried an illegal firearm and opened fire on officers.
