The Justice Department is intervening in support of Elon Musk’s xAI in a lawsuit brought by the NAACP over alleged air pollution from a data center facility in the Memphis, Tennessee, area. The NAACP claims xAI’s operation of a “Colossus Gas Plant,” which supplies power to the company’s Colossus 2 data center, violates the Clean Air Act because xAI did not obtain the required air pollution permit. Multiple outlets report that the Trump administration is asking the court to dismiss the case. The government argues the lawsuit raises national security concerns, saying the relief requested could threaten operations of a data center used by the military. In parallel, coverage notes that xAI is seeking dismissal of the NAACP’s claims. The dispute centers on whether the facility’s power generation complies with environmental permitting requirements, and whether court action affecting the plant would create security risks. The matter is currently being considered in federal court, with the DOJ’s intervention aimed at ending the case before it proceeds.
