text:  The FBI identified the suspect as Thomas Matthew Crooks, a 20-year-old from Bethel Park, Pennsylvania. Bethel Park is about 40 miles or so from Butler, where the Trump rally was taking place. Our colleague Stephen Fowler has confirmed that Crooks was a registered Republican. That's according to Pennsylvania voter registration records. Crooks also donated $15 in 2021 to Act Blue, which is a Democratic allied organization. That's according to FEC data.
