Hawley Becomes First Senate Republican to Back Data Center Moratorium

Senator Josh Hawley of Missouri on Wednesday, Nov. 11, endorsed a temporary nationwide pause on data center construction, becoming the highest-ranking Republican — and, per the Washington Examiner, the first Senate Republican — to back a federal moratorium, Politico reported.

Hawley didn't introduce a bill. He didn't name one, either. He made the call in a post on X listing what Senate Republicans should accomplish in the lame-duck session before the new Congress is seated in January, and the list put a "MORATORIUM on data centers" alongside defunding Planned Parenthood, suspending the federal gas tax, funding rural hospitals and passing the SAVE America Act, the Washington Examiner reported.

The post set out no duration for the pause. Republican leaders have not endorsed a moratorium, and no vote is attached to Hawley's call.

Who else supports a federal pause?

Until now, the push came from the party's progressive flank. Senator Bernie Sanders of Vermont and Representative Alexandria Ocasio-Cortez of New York introduced the Artificial Intelligence Data Center Moratorium Act in March. That bill would halt new data center construction and upgrades until Congress passes laws covering three areas:

• AI safety rules
• Worker protections
• Sharing AI wealth

It would also bar future data centers from raising utility bills or receiving subsidies. When the bill dropped, E&E News reported the idea lacked broad support in either party.

What does Hawley's own legislation do?

Hawley is not new to the data center file. He has already written a data center bill with Senator Richard Blumenthal, a Connecticut Democrat, that would make data centers find their own power sources rather than pass costs to household ratepayers, E&E News reported.

The Senate this week advanced a separate bipartisan permitting bill that would make data centers pay for their grid upgrades.

Does a moratorium have a path this year?

Not a clear one. Republicans control both chambers in the lame-duck session, and their leadership has shown no appetite for a construction pause. Hawley's endorsement is a position statement, not legislation with a vote on the calendar.

But the politics have moved fast since the Nov. 3 midterms, in which data center opposition featured in local races and ballot measures. Michigan Democrat Will Lawrence won a House seat running on a moratorium pledge. New York has paused new hyperscale projects. OpenAI has promised to pay its campuses' power costs.

That's the context for Hawley's post: a Republican senator from Missouri aligning with Sanders and Ocasio-Cortez on one of the AI industry's most contested infrastructure questions, at the moment when local resistance to data center buildouts has started producing electoral wins.

For chip suppliers and hyperscaler customers, the endorsement signals that federal intervention in data center siting is no longer a purely progressive cause. Whether it becomes law depends on whether Hawley's colleagues follow him — and so far, none in the Senate Republican conference have.
