title: The U.S. Department of Justice (DOJ) has intervened in a lawsuit against Elon Musk's AI company, xAI, arguing that its Colossus 2 data center is critical to U.S. national security.
description: "The NAACP sued xAI in April 2026 under the Clean Air Act, alleging the company was operating gas turbines without the necessary permits to power its AI facility. The turbines are located in Southaven, Mississippi, near the data center in Memphis, Tennessee. According to the lawsuit, the number of turbines has increased from 27 to 57 since the case was filed.\n\nxAI maintains that the turbines are exempt from Mississippi permitting requirements because they are mounted on trailers and classified as temporary mobile equipment.\n\nOn Monday, the DOJ filed court documents arguing that shutting down the turbines could harm U.S. national, economic, and energy security. The department stated that the facility supports military AI capabilities.\n\nA declaration from the Defense Department's Chief Digital and AI Officer, Cameron Stanley, said Grok is one of only four AI models approved for mission-critical use on classified U.S. government networks and has been utilized in recent military operations involving Iran.\n\nThe DOJ, xAI, and the State of Mississippi are jointly seeking dismissal of the lawsuit.\n\nSource: Bull Theory"
