"We need a federal moratorium on AI data centers." ... "The AI Data Center Moratorium Act of 2026 would do that by instituting an immediate federal moratorium on AI data centers until strong national safeguards are in place to ensure that: AI is safe and effective — preventing executives in the AI industry from releasing harmful products into the world that threaten the health and well-being of working families, our privacy and civil rights and the future of humanity.

Assessments
The promise was to introduce and support federal legislation for an immediate AI data center moratorium, not to guarantee enactment. As a sitting U.S. senator, Sanders materially fulfilled that promise when he and Rep. Alexandria Ocasio-Cortez announced and introduced the AI Data Center Moratorium Act on March 25, 2026, and subsequent reporting shows he continued advocating for it. Evidence that the bill later stalled affects policy enactment, but it does not negate delivery of a promise centered on legislative introduction and support.
Multiple credible sources confirm that Senator Sanders introduced and actively supported federal legislation to impose a moratorium on AI data centers until national safeguards are enacted. However, there is no evidence in the record that the legislation was enacted or implemented. Therefore, the promise to introduce and support legislation was fulfilled, but the final outcome—an actual moratorium—was not delivered.
Multiple pieces of evidence from March 2026 clearly show that Senator Sanders introduced and supported federal legislation to impose a moratorium on AI data centers until safeguards are in place. However, there is no evidence the legislation passed or that a federal moratorium was enacted, only that Sanders made a significant legislative attempt by introducing and advocating for the bill. Therefore, the promise to introduce and support such legislation was fulfilled (delivered), but the broader promise to actually enact the moratorium remains only partially fulfilled.
