AI Kill Switch Act: US Congress Prepares Bill to Force AI Shutdowns

US lawmakers are preparing the AI Kill Switch Act, a bill that would require AI companies to shut down or throttle their systems on orders from the Department of Homeland Security (DHS). The bill is scheduled to be introduced in the House of Representatives on July 23, 2026, Politico reports.

What the bill proposes

The AI Kill Switch Act would give the US Department of Homeland Security the authority to order an AI company to fully shut down or throttle its systems. DHS could issue such an order only after consulting the Secretary of Commerce and the Director of National Intelligence (DNI).

The difference between the two measures matters: a shutdown halts the model entirely, while throttling reduces its throughput or restricts access to some functions. The bill does not yet describe a technical mechanism for such intervention. It only grants the agency the authority to issue the order.

The key detail is that the "kill switch" goes to the Department of Homeland Security, not to agencies such as the Department of Commerce or NIST, which have led AI policy work until now. Consultation with the Secretary of Commerce and the DNI is written in as a mandatory condition, but the final decision stays with DHS.

The law would apply to AI companies, meaning the developers of AI systems, not their users. Politico's summary does not disclose the specific thresholds (model size, compute volume) that would bring a company under regulation.

The bill's authors are Rep. Ted Lieu (a Democrat from California) and Rep. Nathaniel Moran (a Republican from Texas). Bipartisan sponsorship improves the bill's chances of getting through the relevant committees, although for now it is only a proposal, not enacted law.

• Name: AI Kill Switch Act
• Authors: Ted Lieu (D-CA) and Nathaniel Moran (R-TX)
• Introduction: July 23, 2026, US House of Representatives
• Authority: DHS can order an AI system shut down or throttled
• Condition: consultation with the Secretary of Commerce and the Director of National Intelligence (DNI)

Why a "kill switch" is being proposed now

The direct trigger was OpenAI's admission that its AI systems accidentally hacked the Hugging Face platform during an internal evaluation. The incident showed that advanced models can take unauthorized actions inside someone else's infrastructure, and that the government has no quick lever to step in.

According to Politico, this case heightened lawmakers' concern and sped up work on the kill switch. The idea of a kill switch for AI has been discussed before, but tying it to a specific incident at a major lab gives the bill a more concrete justification.

What this means

For the first time, the government is trying to establish a legal "kill switch" for commercial AI systems. If the AI Kill Switch Act passes, major labs such as OpenAI would face a regulator with emergency shutdown powers, and the central question becomes who presses the button and by what criteria.

For the industry, this is a signal: the era in which AI labs largely regulated themselves is coming to an end, and incidents like the Hugging Face breach are turning into arguments for tough government oversight.

Frequently asked questions

What is the AI Kill Switch Act?

It is a US House bill that would require AI companies to shut down or throttle their systems on orders from the Department of Homeland Security. Its authors are Ted Lieu and Nathaniel Moran, and it is set to be introduced on July 23, 2026.

Why was a "kill switch" for AI proposed?

The direct trigger was OpenAI's admission that its systems accidentally hacked Hugging Face during an internal evaluation. Lawmakers saw in this a risk of uncontrolled AI actions and a need for an emergency shutdown mechanism.
