During a House Oversight Committee hearing, Secret Service Director Kimberly Cheatle admitted that her agency's failure to prevent the July 13 assassination attempt on former President Donald Trump marked its 'most significant operational failure' in decades. Cheatle took full responsibility for the security lapses, which resulted in Trump being wounded and one attendee dead. Despite her acknowledgment of accountability, Cheatle could not identify a single person responsible for approving security plans, leading to bipartisan calls for her resignation. The assailant, Thomas Matthew Crooks, was shot dead by a Secret Service sniper shortly after opening fire. Cheatle vowed to implement corrective measures to prevent future incidents, although she retains support from President Biden and Homeland Security Secretary Mayorkas. The incident has raised serious questions about the Secret Service's security protocols at political events.
