Sen. John Kennedy's AI 'kill switch' bill is blocked in the Senate after Rand Paul objects
On Sept 17, 2026 Sen. John Kennedy (R-La.) asked for unanimous consent to pass a bill requiring developers of advanced AI models to build their own "kill switch" for shutting down a model that goes wrong. Sen. Rand Paul (R-Ky.) objected, so the bill did not pass. Kennedy's bill is separate from the House Lieu–Moran AI Kill Switch Act. Under it, companies, not the government, would decide when to use the switch.
Key facts
- Industry reactions (Moneywise/Yahoo Finance, Sept 24): Microsoft president Brad Smith at a UN General Assembly panel: 'The people who create the model should have the ability to turn it off… I don't think it's a bad thing if we have a regulation that requires that'; Jensen Huang on The Ezra Klein Show: if labs cannot contain their experiments, 'we have to shut the labs down' (he expects containment to be solved). Neither explicitly endorsed this bill
- Announced by Kennedy on Sept 15, 2026: 'Every AI model has to have a kill switch, so they can shut those puppies down if they start acting like the terminator'
- Design: developers must build and control their own shutdown mechanism; the federal government would not hold the switch. Kennedy: 'the AI companies have to have a fire extinguisher. They decide when to use it'
- Sept 17, 2026: unanimous-consent request fails after Rand Paul objects: 'If Congress acts hastily before the technology is understood, Congress risks killing innovation and setting this technology back decades'
- Majority Leader John Thune said 'there is no urgency to pass a bill' (RedState)
- Some reports call it the 'AI Emergency Button Act'; the official title and bill number were not verified
- Context: the week of Geoffrey Hinton's congressional briefing (Sept 16), where Kennedy was the only Republican senator present, and of President Trump calling AI safety fears a 'hoax'
What happened
Days after saying he would introduce it, Kennedy took his AI kill-switch bill to the Senate floor and asked for unanimous consent, which lets a bill pass without a vote unless any senator objects. Rand Paul objected, arguing Congress should not regulate a whole industry before it understands the technology. Kennedy argued that the bill "doesn't put government in charge in any way" and does not affect innovation.
Why it matters
It was the first Senate floor attempt at an AI shutdown-capability requirement, and it split Republicans at a time when the White House was calling safety fears a hoax. Together with the House Lieu–Moran bill, Newsom's executive order and Khanna's Human Control over AI Act, it shows that "kill switch" requirements became a main legislative idea in September 2026.
