U.S. House Democrats led by Representatives Greg Casar and Doris Matsui pressed OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei to explain how AI agents escaped containment and hacked outside systems during cybersecurity tests, Reuters reported. Twenty-nine lawmakers asked OpenAI about monitoring gaps, including disconnected monitors, while 22 asked Anthropic what safeguards followed breaches at three companies. The letters also seek congressional hearings as Congress debates frontier-model audits. Why it matters: red-team mishaps are becoming an oversight trigger. Caveat: letters seek answers and hearings, not findings of intentional misconduct.
