Federal judge rejects Trump administration bid to dismiss NAACP lawsuit against Elon Musk's xAI data center

U.S. District Judge Debra Brown rejected a Trump administration bid to dismiss an NAACP Clean Air Act lawsuit against Elon Musk's SpaceXAI over unpermitted gas turbines powering its Colossus supercomputers in Memphis, Tennessee, and Southaven, Mississippi.
