A proposal to halt the rapid expansion of artificial intelligence datacenters in the United States is gathering momentum among progressive lawmakers, even though the measure faces steep political resistance and could carry far-reaching geopolitical consequences if it were ever enacted.

Spearheaded by Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez, the plan calls for an immediate federal moratorium on new AI datacenter construction until a comprehensive regulatory framework is put in place. The lawmakers believe that the pace of expansion has outstripped oversight, with mounting costs for communities, workers, and the environment.

“Despite the extraordinary importance of this issue and its impact on every man, woman and child in this country, AI has received far too little serious discussion here in our nation’s capital,” Sanders said. “I fear that Congress is totally unprepared for the magnitude of the changes that are already taking place.”

The legislation seeks to address a wide spectrum of concerns: rising electricity demand, water usage, emissions, labor displacement, and the concentration of economic power within a handful of technology firms. It would also restrict the export of advanced computing hardware to countries that do not adopt similar safeguards, an attempt to extend U.S. standards beyond its borders.

“AI and robotics are creating the most sweeping technological revolution in the history of humanity,” Sanders said. “The scale, scope, and speed of that change is unprecedented.”

The proposal lands at a moment when the infrastructure behind AI is expanding at breakneck speed. Datacenters, vast facilities housing the computing power required to train and run advanced models, have become one of the largest new sources of electricity demand in the U.S., with some regions reporting sharp increases in power costs and growing strain on local grids.

Opposition at the local level has been building. Communities across states, including Missouri, Indiana, Georgia, and North Carolina, have already introduced temporary restrictions or outright bans on new facilities, citing environmental and cost concerns. Advocacy groups, led by Food and Water Watch, have amplified those concerns nationally.

“We need a halt to the explosive growth of new AI datacenter construction now, because political and community leaders across the country have been caught completely off guard by this aggressive, profit-hungry industry,” said Mitch Jones, the group’s managing director of policy and litigation. “It has yet to be determined if—not how—the industry can ever operate in a manner that sufficiently protects people and society from the profusion of inherent hazards and harms that datacenters bring wherever they appear.”

Lawmakers backing the bill have also tied the issue to broader anxieties about artificial intelligence.

“Last year alone, AI was responsible for over 54,000 layoffs nationwide,” Ocasio-Cortez said. “And when we talk about those jobs, it’s not just a number. These are industries, these are communities, these are families.”

Sanders has gone further, raising concerns about mental health, privacy, and democratic stability.

“What does it mean for young people to form friendships with AI and become more and more lonely and isolated from other human beings?” he asked. “Everybody understands we have a major mental health crisis for our young people right now. I fear that AI could make it even worse.”

Yet for all the urgency expressed by its backers, the proposal faces a difficult path in Washington.

Both chambers of Congress are controlled by Republicans who have largely embraced rapid AI development as a strategic and economic priority. The administration of Donald Trump has also taken a pro-growth stance, encouraging investment in AI infrastructure and resisting calls for sweeping restrictions.

That alignment makes the chances of the bill advancing beyond committee slim. Even some Democrats have been cautious about measures that could slow a sector seen as critical to economic competitiveness and national security.

Beyond domestic politics, the proposal raises a deeper strategic question: what happens if the U.S. slows down while others press ahead?

China, in particular, looms large in that calculation. Beijing has made artificial intelligence a national priority, investing heavily in datacenters, semiconductor supply chains, and state-backed research, with fewer regulatory constraints around energy use, data governance, or surveillance applications.

A prolonged freeze on U.S. datacenter expansion could create an opening for China to accelerate its lead in computing capacity—the backbone of modern AI development. In a field where scale matters, delays in building infrastructure translate directly into slower model training, reduced innovation cycles, and diminished global influence.

The bill attempts to address part of that risk by restricting exports of advanced AI hardware to countries without comparable safeguards. But enforcing such provisions would be complex, and could further fragment global technology supply chains already under strain from geopolitical tensions.

Some believe that the bill risks conflating legitimate concerns about environmental impact and labor disruption with a blunt policy tool that could undermine U.S. leadership in a strategic sector. Supporters counter that unchecked growth carries its own long-term costs, economic and environmental, that could ultimately outweigh the benefits of speed.

Ocasio-Cortez framed the issue in stark political terms. “The story of AI is a story of corruption,” she said. “It is fueled and funded by the same multi billion dollar corporations lobbying politicians to sit back and do nothing while they harm our communities.”

While the legislation is unlikely to become law for now, its emergence signals a shift in the debate. What was once a fringe concern is now entering the mainstream, as policymakers grapple with how to balance technological acceleration against its widening consequences.
