Congress to question Discord, Reddit, Twitch, and Valve over role in Kirk shooting

In the wake of conservative influencer Charlie Kirk’s killing, House Oversight and Government Reform Committee Chairman James Comer has called on the CEOs of Discord, Reddit, Twitch, and Valve to testify at an Oct. 8 hearing on online radicalization.

The hearing follows claims that the accused shooter — a 22-year-old white man from Utah — may have been influenced by extremist communities online. “Congress has a duty to oversee the online platforms that radicals have used to advance political violence,” Comer said in a press release. “To prevent future radicalization and violence, the CEOs…must appear before the Oversight Committee and explain what actions they will take to ensure their platforms are not exploited for nefarious purposes.”

Federal investigators are still working to determine the shooter’s true motivations, though Robinson's mother told police he learned left of center politically, according to USA Today. Bullet casings recovered at the scene carried meme-laden inscriptions referencing Helldivers 2, anti-fascist themes, and furry culture jokes from 4chan. While early theories pointed to online radicalization, leaked Discord logs paint a far murkier picture of a young man whose friends describe as apolitical, more interested in video games and guns than ideology. A Reddit spokesperson told Mashable their internal review has so far turned up no evidence that the suspect was active on the site.

Earlier this week, Utah Governor Spencer Cox reported that the shooter remains uncooperative, but lawmakers are pressing ahead with scrutiny of the platforms. These hearings have become a familiar ritual in the United States, where mass shootings are frequent and tech companies are regularly accused of enabling extremist networks. Discord and Twitch were both investigated by state attorneys general after the 2022 Buffalo shooting at a supermarket.

Discord, for its part, has already signaled it will cooperate. "We have received the Committee’s invitation and welcome the opportunity to testify," a spokesperson told Mashable. "We continuously engage with policymakers on these critical issues and look forward to continuing this important dialogue next month."
