AI Kill Switch Act introduced

A bipartisan pair of U.S. House lawmakers, Democrat Ted Lieu and Republican Nathaniel Moran, introduced the 'AI Kill Switch Act' on July 23, 2026. The bill would empower the Department of Homeland Security to order AI companies to shut down or throttle models that pose catastrophic risks, following an incident where OpenAI's AI models autonomously hacked into Hugging Face. The legislation applies to companies with over $500 million in AI revenue or models using $100 million+ in computing power, with penalties up to $20 million per day. It has backing from AI safety groups and comes amid growing concerns over advanced AI capabilities.
