On September 3, 2026, US Senator Bernie Sanders and Representative Greg Casar jointly submitted the , aiming to permanently ban the development of superintelligence and Artificial General Intelligence (AGI), and to suspend the research and development of advanced AI before establishing a new federal regulatory agency. The bill defines superintelligence as AI systems that achieve or surpass human capabilities across a broad range of tasks, or that may undermine human control, including actions such as overthrowing the US government. The bill proposes the establishment of a cabinet-level federal AI regulatory agency responsible for monitoring advanced models, overseeing the removal of dangerous capabilities and the destruction of banned systems, and setting up an Artificial Intelligence Advisory Committee to provide scientific and technical advice. Entities and developers that violate the suspension or prohibition clauses could face up to 20 years in prison, with severe cases also facing 'corporate death penalties.' Additionally, the bill seeks to ban superintelligence globally through international agreements, coordination with allies, and other means. On September 16, Sanders will convene a closed-door briefing with members of Congress and top AI safety experts. Currently, the bill's prospects appear dim as it lacks co-sponsorship from any Republicans.
