White House moves to derail NAACP suit over xAI gas turbines powering Grok

The Trump administration asks a Mississippi federal court to dismiss the NAACP’s Clean Air Act suit against xAI and its unit over alleged unpermitted gas turbines at the Colossus Plant powering the Grok data center, arguing federal enforcement isn’t needed after the Mississippi DEQ deemed some turbines mobile sources not subject to permits. The NAACP contends the turbines threaten health in Black communities, while SELC warns that blocking citizen enforcement could undermine environmental justice. The case, in the Northern District of Mississippi, also touches on national security claims tied to Grok’s military data-center uses.
