Reps. Jay Obernolte (R-Calif.) and Lori Trahan (D-Mass.) released a 269-page discussion draft of the Great American Artificial Intelligence Act of 2026 on June 4, and by the end of the day the coalition that would need to carry it was already fracturing. It’s the most ambitious federal AI governance proposal to reach paper, and it’s arriving into exactly the political geometry that killed the last one.

The bill is organized into four titles covering frontier governance, workforce, cybersecurity, and R&D. It defines “large frontier developers” by a $500 million prior-year revenue threshold, imposes disclosure, third-party audit, and whistleblower-protection obligations on that tier, extends the Cybersecurity Information Sharing Act of 2015 through fiscal 2035, and codifies a Center for AI Standards and Innovation inside the Department of Commerce.

The fight is over one provision: a three-year preemption of state laws that specifically regulate AI model development. Per a summary from Trahan’s office, California’s AB 2013 and part of TFAIA would fall. State use and deployment laws survive.

The political memory here’s fresh. The Senate stripped an identical preemption concept from the Big Beautiful Bill 99–1 last year, and the House Democratic Commission on AI, whose members include Obernolte’s former Task Force co-chair Ted Lieu, said the draft “cannot serve as the basis for productive dialogue.” Co-sponsors Scott Franklin, Suhas Subramanyam, Erin Houchin, and Scott Peters give the effort bipartisan cover, but not the votes.

Outside groups split along the expected axis. Brendan Steinhauser, CEO of the Alliance for Secure AI, backed the frontier-risk focus but rejected preemption: “A national AI standard should protect at least as much as it preempts.” NetChoice’s Patrick Hedger called the bill “commendable” while flagging concerns about the safety testing and audit regime.

Sponsors are collecting stakeholder feedback before a formal introduction at Energy and Commerce. The 99–1 vote is the number everyone in the room is counting against.
