Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez introduced the Artificial Intelligence Data Center Moratorium Act on Wednesday, calling for a nationwide pause on the approval and construction of all new AI data centers until Congress passes federal legislation establishing protections for workers, consumers, civil rights, privacy, and the environment.
The bill puts two of the most prominent progressive voices in Washington on direct collision course with the Trump administration, Big Tech, and a trillion-dollar AI infrastructure buildout that shows no signs of slowing.
What the Bill Would Do
The moratorium would halt all new AI data center construction across the United States. The freeze would remain in place until federal AI legislation is passed that specifically addresses worker protections, consumer safeguards, environmental standards, civil rights, and privacy. There is no fixed timeline - the pause lifts only when qualifying federal regulations exist.
Sanders introduced the Senate version Wednesday. Ocasio-Cortez is expected to follow with a companion bill in the House in the coming weeks.
The Case Sanders Is Making
Sanders has been building toward this moment for months. On Tuesday night, he spoke on the Senate floor for thirty minutes on AI's risks and the concentration of power among a small group of tech billionaires. His argument is direct: Congress is moving too slowly while a handful of companies make decisions that will reshape the economy, democracy, and the future of work without meaningful public oversight.
He pointed to Meta's data center project in Louisiana - a facility the size of Manhattan that will consume as much electricity as 1.6 million homes - as an example of the scale of infrastructure being built with virtually no democratic input. His core message: the economic gains from AI are flowing to wealthy tech owners, not workers, and communities are being left to absorb the environmental and financial costs.
The Opposition Is Already Loud
The bill is widely expected to fail in the current Congress. Republican leadership has shown no appetite for a moratorium, and the pushback is coming from both sides of the aisle. Democratic Senator John Fetterman of Pennsylvania sided with Interior Secretary Doug Burgum's framing, arguing that a data center moratorium amounts to handing the lead in AI to China. The Trump administration's position is the opposite of a pause - last week the White House called on Congress to streamline federal permitting for AI infrastructure and preempt state-level AI regulations it views as too restrictive.
The Grassroots Pressure Is Real
Even if the federal bill goes nowhere, it reflects a genuine and growing backlash at the local level. According to Good Jobs First, at least 63 local data center moratorium actions have been introduced, considered, or adopted across dozens of towns and counties, with roughly 54 already passed. At least 12 states have filed data center moratorium bills in the current legislative session. Food and Water Watch, which became the first national organization to call for a moratorium in 2025, celebrated the bill and called on other members of Congress to move quickly to support it.
What This Means for Business
For companies planning AI infrastructure investments, the bill is a signal worth watching even if it does not pass. The political environment around data center construction is shifting. Energy costs, water consumption, noise pollution, and land use are no longer abstract policy concerns - they are active legislative battlegrounds in dozens of communities nationwide.
The gap between the federal government's pro-growth posture on AI infrastructure and the grassroots resistance building in local communities is widening. Sanders and AOC's bill will not stop a single data center from breaking ground in the near term. But it puts the resource costs of AI infrastructure squarely on the congressional agenda at a moment when that debate was already arriving whether Washington was ready for it or not.
