What we know about the Trump rally gunman so far

The gunman who allegedly tried to assassinate former President Donald Trump was bullied in high school and didn’t fit in with other students, former classmates told CNN on Sunday.

This November, Thomas Matthew Crooks was set to reach a political milestone: The first presidential election he was old enough to vote in. A 20-year-old living in a crucial swing state, Crooks had already shown potential signs of interest in politics, making a small political donation as a teenager and registering to vote just a week after he turned 18. But instead of casting his ballot this year, according to law enforcement, Crooks traveled an hour north of his home, climbed to the roof of a building, and opened fire on former President Donald Trump during a campaign rally — leaving him bloodied and coming inches away from killing him. Crooks’ attack, which killed one spectator and critically injured two others, rocked American politics to its core, with elected officials from both sides of the aisle condemning the violence and warning of the dangers of the country’s deep polarization. So far, investigators haven’t found any evidence on social media or other writings by Crooks that might help identify his motive for the attempted assassination, law enforcement officials say. But CNN interviews with a half-dozen former classmates and neighbors of Crooks painted him as quiet and aloof, with classmates remembering him as a misfit in high school. And a review of public records suggests he may have had divergent political leanings, with Crooks registering to vote as a Republican but making a small donation to a Democratic-leaning group.
