He was the public face of Turning Point USA, a political organization that focused on getting more youth in the USA to turn conservative / Republican, to vote, and to adopt a more conservative culture. By “public face”, I mean he was 17 when he cofounded it with an octogenarian and a billionaire funder.

I think he and the org were active on Twitter, but they were MUCH more active on YouTube, and short form video (Instagram, TikTok).

It’s not even clear we know who the shooter is (still conflicting reports about whether the suspect has been arrested, let alone a confirmed identity). Too soon to know what the motive is.
