June 17 (UPI) -- The Department of Justice is trying to quash a lawsuit against a power plant that supports an xAI data center and is arguing that the turbines are essential to national security. The suit, filed by the NAACP and several environmental groups against Elon Musk's xAI, alleges that a power plant in Southaven, Miss., is operating without permits and violates the Clean Air Act. The plant powers the xAI Colossus 2 data center, which is over the state line in Memphis, Tenn. Colossus 2
