More than 200 state lawmakers from across the country have sent a joint letter to Congress, urging federal lawmakers to reject any proposal that would preempt state authority over artificial intelligence regulation. The coordinated push marks a significant show of force from state-level officials who argue that a federal takeover would stifle innovation and undermine local governance.
Why the opposition is growing
The letter, signed by legislators from both parties, warns that a preemption measure would block states from crafting rules tailored to their own economies and populations. AI affects everything from hiring algorithms to medical diagnostics, and state lawmakers say they need flexibility to respond to emerging harms without waiting for Washington. The signatories come from states with widely different approaches to tech oversight, but they share the view that a one-size-fits-all federal law would be a mistake.
The federal-state tension at the heart of the debate
The pushback highlights a deepening rift between those who want a unified national AI framework and those who believe states should serve as laboratories of democracy. Industry groups have often favored preemption to avoid a patchwork of state laws, but these lawmakers argue that preemption would actually slow progress by freezing out local experimentation. Colorado, for example, recently passed its own AI bias law. California is weighing multiple bills. A preemption rule would likely wipe those efforts off the books.
What the preemption proposal would do
Though the exact language of the proposal hasn't been made public in detail, the lawmakers' letter describes it as a measure that would bar states from enacting or enforcing any AI regulation that goes beyond federal standards. That could mean states could no longer require transparency in algorithmic decision-making or impose liability for AI-caused harm unless Congress acts first. Critics say that would leave consumers and workers exposed while federal rulemaking drags on for years.
“State lawmakers are on the front lines of AI governance,” the letter states, according to a summary released by one of the organizing groups. “We see the real-world impacts of AI every day, and we know that waiting for Congress is not an option.”
The signatories include state senators, assembly members, and delegates from at least 35 states. They're asking Congress to hold hearings on the preemption proposal before any vote, and to consult with state officials who would be directly affected.
Congress has not yet scheduled a vote on any AI preemption bill. But several committees are examining the issue, and industry lobbyists have been pressing for a federal standard that would override state rules. The debate is likely to intensify in the coming months.
