shooter per NYTimes https://www.nytimes.com/2024/07/14/us/politics/trump-gunman-thomas-crooks.html "The gunman did not have a criminal history reflected in Pennsylvania’s public court records, and officials said they had not identified a motive. A voter-registration record showed that Mr. Crooks was registered as a Republican, though federal campaign-finance records show he donated $15 to the Progressive Turnout Project, a liberal voter turnout group, through the Democratic donation platform ActBlue in January 2021."
