What happened
Introduced on 19 October 2026 (119th Congress), H.R.9917, the 'AI Kill Switch Act', would amend the Homeland Security Act of 2002 to require certain entities to maintain a technical capability with respect to shutting down certain technology (i.e., a capability to disable/kill frontier AI systems).
Why it matters
A frontier-AI control bill, it would impose a first federal statutory requirement that certain entities maintain a 'kill switch' capability for AI systems, with DHS oversight. Although only introduced, it reflects the direction of travel for federally mandated AI shutdown/containment capabilities and would materially raise the compliance bar for frontier model developers if enacted.
Action needed
Frontier AI developers and large deployers should track H.R.9917 for progression; model architecture and deployment design (containment, independence of interrupt mechanisms) should anticipate a potential federal kill-switch capability obligation.
