Is social media to blame for the White House Correspondents' Dinner shooting?

We're learning a lot more about the online posts of Cole Tomas Allen, the man from Torrance charged with trying to kill President Trump at the White House Correspondents' Dinner. Back in 2022, he posted largely on X about video games and told users to check out his YouTube channel, which featured dozens of short videos about the Nintendo game Super Smash Bros. By 2024, archived tweets show him re-sharing political content from other users, including ones that compared President Trump to Hitler. KNX News' Brian Douglas spoke with social media expert Karen North of USC about the role social media plays.
