What we now know about the shooter:
It appears he was a 4Chan Groyper possibly a Nick Fuentes follower.
He came from a wealthy conservative family.
The bullet casings are mainly 4Chan Groyper memes:
"Hey fascist! Catch!" with the arrow symbols is from a video game called Hell Divers, it calls in a huge bomb. Popular phrase with the Groyper group
"Oh bella ciao, bella ciao, bella ciao, ciao, ciao" is from Hearts of Iron IV, a WWII strategy game, play as Hitler if you like. It's also often wrongly associated with Italian Anti-Fascists. Again popular with the Groyper group
"If you read this, you are gay LMAO" - not exactly something LGBTQ supporters say but again popular on 4Chan message boards
"Notices, bulges, OwO what's this?" - It's literally a 4Chan meme about investigating someone for being trans, popular in the Groyper community
He did wear a Trump costume on Halloween some time back.
He is NOT the same person who donated $200 to Trump's campaign.
TRN on the bullets is the name of the manufacturer. Kash Patel is an idiot.
The memes and Anti-Fascist stuff are directly from Nick Fuentes' groypers group. They are displayed constantly in their message boards INCLUDING calling Kirk a fascist.
Fuentes and his Groypers have repeatedly disrupted Kirk's events and called him fascist for not taking a hard enough stance on Immigration and for being Pro-Israel (Fuentes is a Holocaust denier and Groypers are insanely antisemitic). They believe Kirk is basically controlled opposition to the America First policy to steer people away from a true America First policy and that Kirk is undermining or watering down the policy.
Even the Reddit message boards and some top Republicans have gone from "The Leftists are violent and blood thirsty" to "...we should pray for this individual like Kirk would want us to."
It is highly unlikely this has anything to do with Epstein. These boards don't seem to care that much about it. ...in fact, quite the opposite since many hail from the Incel community...
