- DOJ is seeking to quash a lawsuit against a power plant operated by Elon Musk’s xAI, arguing that its gas-powered turbines are vital to national security interests, including the war in Iran.
- Trump’s Justice Department wants to shield Musk’s xAI from accountability for its illegal pollution, attempting to grab power from impacted communities, the courts, and Congress.
- xAI continues to operate without a permit, violating the Clean Air Act, and has installed 59 unpermitted turbines in Southaven, Mississippi.
- NAACP alleges that xAI's datacenter has the capacity to emit over 5,000 tons of harmful nitrogen oxides per year, making it one of the top polluters in the region.
- DOJ is asking a federal court to dismiss the lawsuit filed by the NAACP against Musk’s xAI, claiming it threatens national security by seeking to shut off power supply needed for AI development.
- Elon Musk’s xAI is being used to train AI models that are critical to the economy and the Department of War, according to the DOJ.
- SpaceX’s data centers have faced protests for over a year due to issues including air pollution and noise.
- Residents near the xAI facility filed a separate class-action lawsuit claiming exposure to constant noise and vibrations.
The Justice Department's intervention in a pollution lawsuit against Elon Musk's xAI highlights a clash between environmental regulations and national security interests.167
The DOJ argues that the unpermitted gas turbines at xAI's Southaven, Mississippi facility are essential for powering AI models critical to the economy and military operations.

The lawsuit, initiated by the NAACP, alleges that xAI operates 59 unpermitted turbines, violating the Clean Air Act and contributing to significant air pollution. These turbines emit over 5,300 tons of nitrogen oxides (NOx) annually, making xAI one of the top polluters in the region.345

The DOJ's motion claims that shutting down the facility would threaten “American national, economic, and energy security”, a position echoed by the Trump administration. Adam Gustafson, a deputy assistant attorney general, stated, “The DOJ will not sit idly by while private organizations use environmental laws to undermine our national security.”
In contrast, the NAACP argues that the DOJ's actions undermine community rights and environmental protections. Abre’ Conner, the NAACP's director of environmental and climate justice, emphasized that “Laws like the Clean Air Act are a bedrock insurance policy for communities to hold polluters accountable.”

Residents near the facility have also filed a class-action lawsuit, citing “near-constant noise, vibrations and other nuisance-level harms.” The ongoing legal battle raises critical questions about the balance between technological advancement and environmental justice.10
“The DOJ is seeking to dismiss a lawsuit against Musk's xAI over pollution allegations, arguing that the datacenter's operations are critical for national security. This intervention has raised concerns about the protection of environmental laws and community health.”
