The U.S. Secret Service has acknowledged significant failures in its security response during the attempted assassination of former President Donald Trump at a rally in Butler, Pennsylvania, on July 13, 2024. Acting Director Ronald Rowe cited 'complacency' among agents and poor communication with local law enforcement as primary factors that allowed the shooter, Thomas Crooks, to open fire, injuring Trump and killing an attendee. The agency failed to provide clear guidance to local partners, leading to confusion and ineffective coordination during the incident. Rowe emphasized that the investigation aims to learn from these failures and implement a 'paradigm shift' in protective operations. The Secret Service is expected to release additional recommendations to enhance security measures as it works to rectify identified shortcomings. Rowe stated that accountability measures will be taken against employees involved but provided no specifics regarding disciplinary actions.
