The U.S. Department of Justice (DOJ) has filed a memorandum requesting the dismissal of the NAACP’s lawsuit against Elon Musk’s xAI (now SpaceX) Colossus 2 data center, arguing that stopping the natural gas turbines needed to run the facility “threatens American national, economic, and energy security.” The DOJ stated that xAI’s Grok model is one of only four AI models used by the military and security agencies to “support mission-critical operations across Secret and Top-Secret classified networks.” The NAACP, through the Southern Environmental Law Center (SELC), sued xAI after an investigation found that the Colossus supercomputer facility used “illegal” generators to power its AI GPUs. The site powered on in July 2024 and became fully operational in May 2025 after receiving 150MW of power. The initial lawsuit, filed in April 2026, cited 27 natural gas turbines at Colossus 2 as noncompliant. As of May 2026, the SELC says 57 turbines are operating on site without a permit, resulting in a 111% increase in nitrogen oxide exhaust, an 83% jump in PM2.5 pollutants, and an 88% uptick in formaldehyde emissions. The SELC stated the Trump administration is “launching an unprecedented attack on the public’s ability to defend themselves.”
