Republican lawmakers recently ordered social media companies to testify before the House Oversight Committee to “examine radicalization of online forum users, including incidents of open incitement to commit violent politically motivated acts” — while notably excluding companies led by Trump’s closest Big Tech allies.

The hearing, scheduled for October 8, comes in the wake of the assassination of conservative activist Charlie Kirk and will focus on four companies in particular: Discord, Reddit, Steam, and Twitch. Conveniently left out of this group are platforms run by prolific Trump donors and allies: Mark Zuckerberg’s Meta (which owns WhatsApp, Instagram, and Facebook), and Elon Musk’s X.

A goal of the hearing is to “prevent future radicalization and violence” stemming from social media platforms. Research shows that social media has played a substantial role in radicalizing individuals, and has long been a hotbed for hate speech — particularly on the platforms excluded from testifying before Congress.
