In a bold legislative move that has drawn swift condemnation from both Silicon Valley and across the aisle, Senator Bernie Sanders (I-Vt.) and Representative Alexandria Ocasio-Cortez (D-N.Y.) introduced the Artificial Intelligence Data Center Moratorium Act on Wednesday, March 25, 2026.
The bill seeks to halt the construction and upgrading of all new AI data centers nationwide until Congress passes "comprehensive AI legislation."
The progressives argue that the freeze is a necessary "time-out" to ensure the technology serves ordinary Americans rather than just "Big Tech owners."
The proposed moratorium currently stands as a primary flashpoint in the national debate over the "Power of Computation."
Its primary mandate involves a list of strict conditions that must be met before construction can resume, including federal pre-release reviews of AI products, protections against job displacement, and mandatory union labor for data center construction.
_ _“This moratorium will give us the time to figure out how to ensure that AI is safe and effective,” Sanders stated, emphasizing that the wealth generated by these facilities must be shared with the public.
The bill will also absorb and expand upon the growing friction between federal authority and local land-use rights.
A critical component of the opposition is the argument that a blanket federal freeze robs states and local communities of their power to manage their own zoning and infrastructure.
Critics like Kevin Frazier of the Abundance Institute noted that more than 100 local communities have already enacted their own restrictions, suggesting that a federal mandate is an overreach into "police powers" traditionally held by cities and counties.
One of the most immediate challenges for the bill is the fierce bipartisan pushback in Washington.
Observers cited the "China First" label given to the bill by Senator John Fetterman as the primary reason it faces an uphill battle.
“It might as well be called the 'Hand China the Lead on AI Act',” warned Adam Thierer of the R Street Institute, arguing that freezing American infrastructure during a global tech race is an act of "stagnation."
Even within the Democratic party, influential voices like Senator Mark Warner have dismissed the proposal as "idiocy."
The establishment of this legislative "declaration of war on computation" follows a massive surge in data center tax revenue that has helped some counties, like Loudoun in Virginia, actually lower car taxes for residents.
While Sanders and AOC argue that the facilities are "fabulously profitable" only for billionaires, the emphasis from economists remains on the capital gains millions of Americans receive through retirement accounts tied to firms like Nvidia and Microsoft.
Director-level policy analysts at the Cato Institute pledged to fight the measure, noting that it contradicts the National AI Policy Framework released by the White House last week.
As the bill heads to committee, the question remains: “Will the push for 'safe and effective' AI lead to a domestic infrastructure freeze, or will the pressure of international competition render this moratorium dead on arrival?” a question that will define the tech policy landscape for the remainder of 2026.
