US lawmakers introduce AI Kill Switch Act giving DHS model shutdown power

Bipartisan House members introduced the AI Kill Switch Act, which would let the Department of Homeland Security shut down or throttle AI models judged dangerous. The proposal would create a federal off-switch mechanism that centralizes emergency AI safety oversight.
Key takeaway
If enacted, cloud and model operators would face a new federal interruption risk keyed to DHS danger determinations rather than only existing voluntary safety regimes.
Context
The bill, introduced on a bipartisan basis in the House, would authorize DHS to shut down or throttle AI systems it deems dangerous, establishing an explicit government kill-switch pathway for deployed models.
That framing shifts part of AI safety debate from model capability claims toward operational control of serving infrastructure, raising compliance and continuity planning stakes for providers subject to US jurisdiction.
