Reps. Jay Obernolte (R-Calif.) and Lori Trahan (D-Mass.) released a 269-page discussion draft of the Great American Artificial Intelligence Act on June 4, and the only provision anyone in Washington is actually arguing about is Title II: a three-year preemption of state laws “specifically regulating the development” of AI models. Mintz’s analysis notes that post-deployment rules and laws of general applicability are untouched, but the developmental freeze is the whole ballgame.

The substantive federal architecture is real. Frontier developers above $500 million in gross revenue face disclosure and catastrophic-risk obligations, with the threshold defined to include harms like 50-plus deaths or $1 billion in property damage. The politics, though, run through what GAAIA displaces. Brad Carson, president of Americans for Responsible Innovation, calls the preemption a “generational mistake,” arguing it converts the emerging state-law floor into a federal ceiling.

That floor is hardening in real time. On May 27, the Illinois General Assembly unanimously passed S.B. 315, mandating annual third-party audits of frontier models with $3 million-per-violation penalties; the bill was sent to Gov. Pritzker on June 26 and takes effect January 1, 2027. Meanwhile, DOJ’s AI Litigation Task Force intervened on April 24 in xAI’s suit to invalidate Colorado’s AI Act (SB 24-205), a federal posture that reads less like neutral enforcement and more like clearing runway for GAAIA.

The choke point is Senate Commerce. Sen. Ted Cruz (R-Texas), who controls markup timing, has promised a summer markup on KOSA and wants AI bills folded in, though he’s been coy on specifics, calling AI legislation “complicated and fraught with peril.” Sen. Marsha Blackburn (R-Tenn.) is negotiating with the White House on a package bundling KOSA, the NO FAKES Act, and age-verification rules with preemption attached. Sen. Richard Blumenthal (D-Conn.) isn’t interested: “Preemption should not be a part of it, period.”

Illinois’s audit regime and the summer markup calendar are now on a collision course, and the sequencing favors whichever side moves first.
