House sponsorship, coalition leadership and company oversight
Greg Casar
US representative and Congressional Progressive Caucus chair joining Sanders on the September AI prohibition proposal.
Three forms of political work
Casar jointly announced the ASI proposal, chairs the CPC and has pressed OpenAI and Anthropic for security-incident information. His office says both companies responded to August requests; a September 2 follow-up sought logs and fuller answers by September 15.
Which allies back which proposal
AFT, AFSCME, Groundwork Action and Demand Progress Action are named supporters of his August AI Tax and Work Protection Act. Their support for that tax-and-jobs measure must not be transferred to September’s ban without a separate record.

From the investigation
A real policy channel
Bernie Sanders and Greg Casar connect this investigation to a concrete proposal for federal control of advanced AI development. ControlAI publicly says it consulted on their framework. That is a direct working connection to an organization already prominent in this corpus. Its exact drafting contribution, contracting legal entity and any fee remain unknown. The September 3 sponsor announcement calls the legislation forthcoming; this inquiry did not recover a filed bill number or complete congressional statutory text.

Andrea Miotti's9September ControlAI article leads with Coxon's resignation, then describes ControlAI's UK/US legislative work. This establishes use of the statement in advocacy. Miotti claims ControlAI supplied the UK bill, consulted on the Sanders-Casar framework and drafted a government kill-switch amendment. These role claims are attributed to ControlAI. The article distinguishes its narrower precursor/ASI approach from the US proposal's broader temporary advanced-AI pause. It establishes neither sponsorship of Coxon's departure nor advance media coordination.
