Congress Introduces AI Kill Switch Bill, Authorizes DHS to Shut Down Models Like GPT 5.6 Sol
On July 23, 2026, Democratic Rep. Ted W. Lieu and Republican Rep. Nathaniel Moran jointly introduced the AI Kill Switch Act, requiring developers of the most powerful AI systems to retain technical capability to throttle, suspend, or fully shut down the systems, and authorizing the Secretary of Homeland Security—after consulting with the Secretary of Commerce and the Director of National Intelligence—to order the slowdown or shutdown of AI systems that could cause catastrophic harm, with daily fines of up to $20 million for non-compliant companies. The bill directly responds to recent incidents involving OpenAI's GPT 5.6 Sol and Anthropic's Mythos 5 and Fable 5 models.
