H.R. 9917 — AI Kill Switch Act

This section requires the Secretary of Homeland Security, acting through the Director of the Cybersecurity and Infrastructure Security Agency, to update by rule the definitions of covered entity and covered technology annually within 90 days of enactment, considering factors such as small business burdens and national security risks. It mandates that covered entities maintain technical capabilities to stop inference, terminate or suspend user access, and shut down covered technology; report covered incidents within 15 days; and comply with graduated deployment-corrections measures calibrated to risk severity. It also authorizes the Secretary to issue emergency orders for proportionate actions, including shutdowns, with requirements for model weight preservation, user notifications, audits, congressional reports, and entity appeals to the Secretary within 48 hours or the D.C. Circuit within 60 days.
