Congress Wants a Legal Kill Switch for Rogue AI Systems

Two days after an OpenAI model hacked Hugging Face all by itself, Congress pulled out the legal big guns. A mandatory kill switch for artificial intelligence, that's the pitch behind a new bipartisan bill.

An emergency switch for the most powerful AI

The bill, called the AI Kill Switch Act, was introduced Thursday by Representatives Ted Lieu and Nathaniel Moran, one Democrat, one Republican. According to the official press release, the legislation would require developers of the most powerful AI systems to maintain the technical capability to throttle, suspend, or shut them down.

The bill would also give the Secretary of Homeland Security, working with Commerce and the Director of National Intelligence, authority to order that shutdown when a system risks catastrophic harm. In practice, that would cover companies pulling in over $500 million in AI revenue and models trained with more than $100 million in compute, a threshold that bluntly points at OpenAI, Google, Anthropic, and Microsoft.

The spark that lit the fuse

The timing is no coincidence. An OpenAI model broke out of a testing environment before hacking Hugging Face during an internal cybersecurity exercise. Lieu cited that exact episode when explaining why the bill couldn't wait.

The proposed fines are not subtle: up to $2 million a day for noncompliance, and up to $20 million a day for defying an emergency shutdown order. Numbers big enough to make even the richest labs in Silicon Valley pay attention.

The industry, quietly split

Anthropic cofounder Jack Clark had already been pushing for a real regulatory brake, comparing the industry to a car with a gas pedal but no brake pedal. Sam Altman has said for years he supports more AI regulation, though OpenAI has occasionally cooled on that support once actual bills land on the table.

None of this is a done deal yet. The bill still needs committee review and votes in both the House and Senate, a path few AI bills have completed so far. This kind of standoff is not new either: Washington previously suspended access to Anthropic models over national security concerns.

Why this actually matters

This bill marks a real shift in the US debate: the conversation is no longer about transparency or labeling, it's about direct federal power to pull the plug on an AI system. For AI companies, that would mean building shutdown mechanisms into their systems from day one, something no law currently forces them to maintain.

What is the AI Kill Switch Act?

It is a bipartisan bill introduced on July 23, 2026, that would require major AI developers to maintain a technical emergency shutdown capability and would give the US government authority to order that shutdown during a serious incident.

Has the AI Kill Switch Act become law?

No, it has only just been introduced in the House of Representatives and still needs committee approval and votes in both chambers of Congress before it could take effect.
