The chairman of the Congressional Progressive Caucus on Monday led a group of House Democrats in calling on the top executives of leading artificial intelligence companies to testify under oath following a series of hacking incidents that underscored the industry’s alarming lack of safeguards. “Advanced AI models pose a clear risk to the safety and security of the American people,” Rep. Greg Casar (D-Texas) and 18 other Democrats wrote in a letter urging House Speaker Mike Johnson (R-La.) The letter points to recent announcements by OpenAI and Anthropic that their AI models went rogue and hacked into the networks of other organizations. Separately, Casar and other House Democrats wrote directly to OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei demanding detailed information about the recently disclosed hacking incidents, which were described as a “chilling leap” for the rapidly developing technology. “Given the serious risk that frontier AI models can pose,” the lawmakers wrote, “it is imperative we have a detailed understanding of how this security incident unfolded, including any potential negligence.”
