In the wake of the July 13 assassination attempt on former President Donald Trump, at least five U.S. Secret Service agents have been placed on administrative leave as investigations reveal significant security failures. These investigations, initiated by the Secret Service, Congress, and the Department of Homeland Security, point to communication breakdowns, including the failure to use radios provided by local authorities, which could have alerted agents to the threat. Pennsylvania Secret Service chief Timothy Burke, among those reassigned, approved the security plan for the event despite concerns about resource limitations due to other commitments, as highlighted by whistleblower accounts. Senator Josh Hawley has raised questions about the agency's claims regarding resource requests and accountability, suggesting deeper systemic issues within the Secret Service. Trump has since enhanced security measures at his rallies, implementing bulletproof glass around his podium. The investigations continue as lawmakers seek to understand how a 20-year-old gunman was able to approach Trump so closely during the event.
