# Sanders and Casar introduce the Ban Artificial Superintelligence Act, with a pause on advanced AI and a new Department of AI

On Sept 23, 2026 Sen. Bernie Sanders and Rep. Greg Casar introduced the Ban Artificial Superintelligence Act (announced as forthcoming on Sept 3). It would permanently ban developing or deploying superintelligent AI and pause advanced AI development until a new Cabinet-level Department of Artificial Intelligence sets safety rules. Violations would carry a "corporate death penalty" and up to 20 years in prison.

## Key facts
- Nov 11, 2026 (Futurism): after Democrats won Congress, a revised draft with Rep. Alexandria Ocasio-Cortez as backer is 'gaining steam': permits from a cabinet-level Department of Artificial Intelligence for 'advanced' AI work, full infrastructure access, up to 20 years in prison for the worst violators and 10-year industry bans for individual employees
- Announced Sept 3, 2026 as forthcoming legislation; formally introduced Sept 23, 2026 (Senate and House press releases)
- Bans superintelligent systems that surpass human intelligence, could overthrow governments or have dangerous abilities such as subverting shutdown commands; NBC says the definition also covers the capacity to automate or accelerate AI R&D
- Pauses advanced AI development until a Cabinet-level Department of Artificial Intelligence, led by a Secretary of AI, sets rules and a model review process
- Penalties: 'corporate death penalty' plus up to 20 years in prison, which Sanders likened to the penalty for unlawfully building nuclear weapons
- Directs the US to seek international agreements so superintelligence is not built anywhere; 19-page bill (NBC)
- Reactions: ControlAI praised it; Gary Marcus opposed it; seen as having long odds in the Republican-controlled Congress
- Follow-up (The Hill, Oct 13): on Monday Oct 12 Sanders answered Sam Altman's remark that people will 'have to just accept some fairly severe cyber incidents from open models, in exchange for the liberty that comes with that' (The Hill places the remark on Politico's 'Decoded' podcast). Sanders on X: 'No, Mr. Altman. We won't accept a severe AI cyberattack in exchange for liberty'; 'If you and other Big Tech Oligarchs make products that commit crimes or disasters, we will hold you accountable for breaking the law'; 'We must PAUSE advanced AI and permanently BAN artificial superintelligence before it is too late.'

## What happened

Casar: "Our bill bans the development of artificial superintelligence and pushes for international agreements so that no one, anywhere, builds AI
too powerful for humans to control." Sanders: "When the future of humanity is at stake, we need binding international safety rules, not voluntary
standards from the industry." The bill came during a run of OpenAI agent-incident disclosures and lab calls for voluntary pacing.

## Why it matters

It is the most far-reaching US federal proposal to date: an outright statutory ban on superintelligence, with a development pause, rather than
reporting or kill-switch rules. It is unlikely to pass, but it moved "ban superintelligence" into mainstream legislative debate.

Caveat: the senate.gov pages return 403 to our fetcher; details come from Rep. Casar's release, NBC and search snippets of the Sanders releases.
