During a House Oversight Committee hearing, U.S. Secret Service Director Kimberly Cheatle faced intense scrutiny from lawmakers over the agency's failure to prevent an assassination attempt on former President Donald Trump at a rally in Butler, Pennsylvania. Cheatle acknowledged the incident as a significant operational failure and took full responsibility but did not offer her resignation. Lawmakers from both parties expressed dissatisfaction with her responses, particularly her refusal to answer specific questions due to ongoing investigations. The attack resulted in Trump's ear being grazed by a bullet, one rally attendee being killed, and two others injured. Several investigations, including those by the FBI and the Department of Homeland Security’s inspector general, are underway to determine the security lapses. Some lawmakers, like Rep. Chip Roy, have called for defunding the Secret Service until accountability is ensured.
