The FBI has released new details and photos related to the attempted assassination of former President Donald Trump during a rally in Butler, Pennsylvania, on July 13, where the gunman, 20-year-old Thomas Matthew Crooks, was shot and killed by a Secret Service sniper. Investigators revealed that Crooks engaged in extensive planning, focusing particularly on Trump's rally while also researching events related to both Trump and President Biden. The released images include the AR-style rifle used in the shooting, a backpack, and improvised explosive devices found in Crooks' vehicle. The FBI has not identified a clear motive for Crooks' actions, noting a 'mixture of ideologies' linked to him, but no evidence of collaboration with others. Crooks had a history of searching for bomb-making information and had considered targeting both major political conventions. The investigation continues as officials analyze Crooks' online activities to better understand his mindset leading up to the attack.
