Feds seek to dismiss lawsuit threatening Mississippi AI plant
The U.S. Justice Department has intervened in a private lawsuit seeking to shut down a large xAI artificial intelligence facility in Southaven, Mississippi. The lawsuit claims the facility's power source violates Clean Air Act permitting, but federal officials argue the plant is critical infrastructure for national security and AI development. The DOJ has requested the lawsuit be dismissed, stating that environmental laws should not undermine national security.
The U.S. Justice Department has formally intervened in a private lawsuit targeting a significant artificial intelligence facility in Southaven, Mississippi, operated by xAI and its subsidiary MZX Tech LLC. The department filed motions yesterday to block the lawsuit, which was initiated by private citizens alleging the facility's power source violates Clean Air Act permitting requirements.
Federal officials, specifically the Justice Department's Environment and Natural Resources Division (ENRD), are siding with xAI, arguing that the facility is critical infrastructure for both the civilian economy and the Department of War, training and developing new AI models. The State of Mississippi had previously determined that no permit was required for the facility's power source. The DOJ warns that an injunction to halt operations, as sought by the plaintiffs, would cut off critical power during an energy emergency and hinder national defense.
Associate Attorney General Stanley Woodward emphasized that enforcing federal law is the responsibility of the Executive Branch, not private groups, and that the DOJ is committed to maintaining constitutional order while protecting national security and promoting American energy and innovation. Principal Deputy Assistant Attorney General Adam Gustafson reiterated that the department would not tolerate private organizations using environmental laws to undermine national security.
The federal intervention is partly linked to a recent executive order by President Donald J. Trump, "Promoting Advanced Artificial Intelligence Innovation and Security," which prioritizes AI development across the government. The ENRD has formally requested the U.S. District Court for the Northern District of Mississippi to dismiss the lawsuit entirely.
