Thomas Matthew Crooks, the 20-year-old gunman who attempted to assassinate former President Donald Trump at a Pennsylvania rally, also researched Princess Kate Middleton and several high-profile U.S. officials, including President Joe Biden, Attorney General Merrick Garland, and FBI Director Christopher Wray. The FBI discovered images and information about these individuals on Crooks' devices after raiding his home. Despite being flagged as a potential threat over an hour before the shooting, Crooks managed to open fire, grazing Trump's ear and causing one fatality and two injuries. His father had alerted police about his concerns before the incident. There are no indications of a specific political or ideological motive behind his actions, but Crooks had searched for information related to major depressive disorder. The FBI and Secret Service continue to investigate the case as a potential act of domestic terrorism.
