Trump’s DoJ intervenes to back Elon Musk in datacenter pollution lawsuit

Justice department urges judge to throw out suit brought by NAACP over xAI’s methane-gas turbines in Mississippi

The Trump administration is coming to the defense of Elon Musk in a lawsuit over claims that his artificial intelligence company, xAI, is polluting residential neighborhoods in north Mississippi. The justice department told a federal court late on Monday to throw out the case.

The lawsuit was filed by the NAACP in April over allegations that xAI and its subsidiary MZX Tech set up dozens of methane-gas turbines to power its datacenter in Southaven, Mississippi, without air permits. The suit claims these turbines emit toxic pollutants in violation of the Clean Air Act, and is asking a judge to block xAI from operating the machines.

The Department of Justice says this datacenter is being used to train and develop AI models that are “critical to the economy and the Department of War” and the turbines are necessary to power the facility. In a 33-page memo filed in Mississippi federal court, the government also claims that under the Clean Air Act, it can terminate such “citizen lawsuits”.

“The Department of Justice will not sit idly by while private organizations use environmental laws to undermine our national security,” said Adam Gustafson, a deputy assistant attorney general for the justice department’s environment and natural resources division.

xAI’s central focus is a chatbot called Grok, which is similar to ChatGPT but has been known for controversy including nonconsensual deepfakes , sexualized images of woman and minors and referring to itself as “MechaHitler” . The justice department wrote in its filing that Grok’s continued availability was “paramount” to national security and the military version of the chatbot had assisted US forces “to deploy over 2,000 munitions to 2,000 distinct targets within 96 hours” in the war against Iran.

xAI’s parent company, SpaceX, had the largest initial public offering in history last week valuing it at more than $2tn. The IPO also minted Musk as the world’s first trillionaire. In recent weeks, xAI entered partnerships with Google and Anthropic to rent space in its datacenters for billions of dollars annually.

Lawyers representing the NAACP said affected communities had long had the right to file suits against polluters and that the justice department cannot simply quash those cases. They added that all companies, even those contracting with the federal government, must follow environmental laws.
