The AI Kill Switch Act, sponsored by Reps. Ted Lieu and Nathaniel Moran, would amend the Homeland Security Act of 2002 to authorize the DHS Secretary to suspend AI systems posing catastrophic risks, with daily fines up to $20 million for noncompliance. Sponsors cite recent incidents involving OpenAI and Anthropic models as justification. The proposal has drawn analyses from progressive, conservative, and libertarian perspectives emphasizing differing concerns over regulation, executive power, and verification of triggering events.
