A U.S. Secret Service agent assigned to protect former first lady Jill Biden accidentally shot himself in the leg at Philadelphia International Airport on Friday, authorities said. Biden was not in the area when the agent was injured during a negligent discharge of his firearm Friday morning, according to Secret Service spokesman Anthony Guglielmi. Initial reports indicated the agent was traveling in an unmarked car when the firearm was accidentally discharged shortly before 9 a.m., noted Philadelphia Police Officer Tanya Little. Other law enforcement officers responded to assist the injured agent, who was subsequently taken to a local hospital. He is now receiving treatment and is reported to be in stable condition. Heather Redfern, public affairs manager for the city’s Department of Aviation, confirmed that airport operations were not impacted by the event.
