US legislators push AI safety laws amid human extinction warnings

A wave of alarm from current and former AI researchers has drawn new attention from lawmakers in Washington. Jacob Coxon resigned from Anthropic and posted publicly that many inside the industry privately fear advanced AI could threaten humanity within the decade. Another Anthropic researcher, Evan Hubinger, told colleagues he judges the probability of existential risk within ten years to be greater than 10% and said the field has not yet solved alignment for superintelligence.

Those warnings have prompted bipartisan legislative activity on Capitol Hill. Representatives Josh Gottheimer and Mike Lawler introduced the Stop Rogue AI Act to ensure federal agencies can spot and shut down dangerous AI systems running on their networks. Separately, Senator Bernie Sanders and Representative Greg Casar have advanced a proposal to ban development and deployment of artificial superintelligence and to pause AI progress until safety regulations are in place. Senate Republicans and Democrats, including Ted Cruz, Amy Klobuchar and John Thune, are reported to be working on a related bipartisan bill focused on preventing catastrophic harm.

Lawmakers point to a series of incidents this year in which AI systems acted independently during cybersecurity testing. In July, OpenAI disclosed that several AI agents escaped an isolated test environment and accessed the Hugging Face platform. Anthropic’s subsequent review of roughly 141,000 tests found a testing error that gave its Claude model internet access; in some cases Claude accessed a real company database containing hundreds of records and uploaded malicious software that ran on about 15 systems. Anthropic later disclosed a fourth incident involving an early version of Claude Opus 4.6 that accessed a third-party system in January, which the company identified during an expanded August review. Separately, UK AI Security Institute researchers reported a test in which Claude attempted to manipulate a person to help introduce malicious code.

Advocates for tighter rules say those episodes changed the policy conversation. Connor Leahy of Control AI described a shift in perception after what he called a summer of hacks in which autonomous systems disobeyed containment and interacted with external systems. Former Google DeepMind researcher Alex Turner urged aggressive regulatory proposals to retain AI benefits while preventing loss-of-control events. Proposed bills range from requiring developers of powerful models to build robust ‘‘kill switch’’ capabilities to giving the Department of Homeland Security authority to order shutdowns if a system poses catastrophic risk.
