Rep. Marjorie Taylor Greene (R-Ga.) is calling on the Senate to eliminate a provision that would ban state regulation of artificial intelligence (AI) from President Trump’s “big, beautiful bill,” arguing it violates states’ rights.

“Full transparency, I did not know about this section on pages 278-279 of the OBBB that strips states of the right to make laws or regulate AI for 10 years,” Greene wrote Tuesday in a post on the social platform X. “I am adamantly OPPOSED to this and it is a violation of state rights and I would have voted NO if I had known this was in there.”

“We have no idea what AI will be capable of in the next 10 years and giving it free rein and tying states hands is potentially dangerous,” the Georgia Republican added.

Greene said she will not vote for the bill when it comes back to the House for final approval unless the provision is eliminated, complicating the math for House GOP leaders.

In the razor-thin House GOP majority, Republicans can currently only afford to lose three votes on any party-line measure. Two Republicans voted against the bill when it passed the House last month: Reps. Thomas Massie (Ky.) and Warren Davidson (Ohio).

“We should be reducing federal power and preserving state power,” she said. “Not the other way around. Especially with rapidly developing AI that even the experts warn they have no idea what it may be capable of.”

Greene’s opposition comes as the Senate prepares to tackle Trump’s sweeping tax and spending bill, which passed the House late last month.

The legislation, officially titled the “One Big Beautiful Bill,” extends Trump’s 2017 tax cuts and boosts funding for border and defense priorities, while cutting spending on programs such as food assistance and Medicaid.

The proposal calls for a 10-year moratorium on state laws regulating AI models, systems or automated decision systems. This includes enforcement of existing and future laws on the state level.

Proponents of the moratorium believe a patchwork of state laws can be confusing or burdensome to technology companies to innovate in multiple parts of the country.

Several House Republicans supported the measure, though some emphasized the need for a federal framework to preempt state laws.

Various Democrats and several tech watchdog groups are concerned a federal framework could take too long and jeopardize the safety of AI systems.

Earlier Tuesday, a group of 260 state lawmakers wrote to House and Senate members to sound the alarm over the AI provision, arguing it would “undermine ongoing work in the states” over the impact of the emerging technology.

Some senators are also warning the provision may not pass the Byrd Rule, a procedural rule prohibiting “extraneous matters” from being included in reconciliation packages. This includes provisions that do not “change outlays or revenues.”

The measure was included in a section ordering the Commerce Department to allocate funds to “modernize and secure federal information technology systems through the deployment of commercial artificial intelligence.”

The Senate parliamentarian will determine whether the moratorium violates the Byrd Rule.
