Thomas Matthew Crooks, the gunman in the assassination attempt on former President Donald Trump, extensively researched events involving Trump and President Joe Biden, with a particular focus on the July 13 campaign rally in Butler, Pennsylvania, where he ultimately opened fire. The FBI has released photos of the firearm and explosives found in Crooks' possession, highlighting his detailed attack planning. Despite nearly 1,000 interviews, investigators have not determined a clear motive but noted Crooks' interest in explosives and major political events. Meanwhile, a group of House Republicans, led by former Navy SEAL Eli Crane and U.S. Army veteran Cory Mills, is conducting an independent investigation, citing distrust in the official congressional task force. This task force, perceived as politically influenced, has promised answers regarding the assassination attempt but faces skepticism about its impartiality and effectiveness.
