In the aftermath of the attempted assassination of former President Donald Trump at a rally in Butler, Pennsylvania, Secret Service Director Kimberly Cheatle has acknowledged responsibility, stating, 'the buck stops with me' but refused to resign. The incident involved a shooter, Thomas Matthew Crooks, who fired from a rooftop, injuring Trump and two others and killing a former firefighter. Criticism of the Secret Service’s handling of the event has led to multiple congressional investigations and an independent review ordered by President Biden. Cheatle has vowed full cooperation with these investigations and emphasized the need for an internal review to prevent future incidents. Video evidence and eyewitness reports indicated security lapses, with rally attendees trying to alert police to the shooter’s presence before the shots were fired. The House Oversight Committee plans to hold a hearing on July 22 to further scrutinize the security failures.
