"DOJ assists Musk’s xAI in NAACP air pollution suit, asks court to toss case" 16 June 2026

...Elon Musk’s company is getting an assist from the Department of Justice, which asked a federal court in Mississippi to toss a case against the company brought by the NAACP.

...SpaceX’s Colossus 1 and 2 data centers in and around Memphis, Tennessee, along with the power plants linked to those facilities, have faced protests for more than a year over issues including air pollution, electricity and water consumption and noise around the facilities...
