Overview
- The Department of Justice moved to intervene in a NAACP Clean Air Act lawsuit and asked a judge to block or dismiss the case by citing a Pentagon sworn statement that xAI’s Grok Gov Model helped U.S. forces deploy over 2,000 munitions to 2,000 targets in 96 hours.
- Pentagon Chief Digital and AI Officer Cameron Stanley said in the filing that Grok is among only a few proprietary models cleared to run on Secret and Top‑Secret networks and that the Defense Department has paid xAI for classified use.
- Plaintiffs allege xAI’s Colossus 2 data center near Memphis uses dozens of trailer‑mounted natural‑gas turbines without state permits, raising local NOx, PM2.5 and formaldehyde exposure concerns and seeking daily civil penalties.
- Lawmakers, civil‑rights groups and environmental lawyers responded by urging stricter limits on military uses of commercial AI and bills to ensure human control over life‑and‑death decisions in warfare.
- Legal experts and advocates say the DOJ’s defense of a private company on national‑security grounds is unusual and could set a precedent that narrows environmental enforcement and forces policymakers to address military dependence on a small set of frontier AI models.
