US Congress has formally invited the CEOs of Twitch, Steam, Reddit, and Discord to testify at a committee hearing on "radicalisation" of online forum users. The committee hearing next month will focus on the radicalisation of online forum users, including cases of open incitement to commit politically motivated violence. “The politically motivated assassination of Charlie Kirk claimed the life of a husband, father, and American patriot," Comer said in the letter. "In the wake of this tragedy, and amid other acts of politically motivated violence, Congress has a duty to oversee the online platforms that radicals have used to advance political violence. "To prevent future radicalisation and violence, the CEOs of Discord, Steam, Twitch, and Reddit must appear before the Oversight Committee and explain what actions they will take to ensure their platforms are not exploited for nefarious purposes."
