Thomas Matthew Crooks, a 20-year-old registered Republican, attempted to assassinate former President Donald Trump at a rally in Butler, Pennsylvania. Crooks spent 48 hours preparing, purchasing ammunition and a ladder, and practicing at a shooting range. The FBI, investigating the incident as domestic terrorism, found Crooks acted alone with motives still undetermined. The attack left one person dead and two critically injured, while Trump suffered a minor ear graze. This event has prompted calls for a full-scale investigation into security lapses and may help the FBI improve its strained relationship with the GOP. Supporters have released T-shirts commemorating the incident, sparking debates over free speech and public safety.
