DOJ Joins xAI Lawsuit Challenging Colorado's AI Discrimination Law

The U.S. Department of Justice (DOJ) has officially intervened in xAI’s lawsuit against the state of Colorado, arguing that a recent state law regulating artificial intelligence systems is unconstitutional.

xAI filed the lawsuit in early April in response to Colorado Bill SB24-205, which mandates that developers of "high-risk" AI systems—such as those used in healthcare, employment, or housing—must disclose and mitigate algorithmic discrimination risks. The law is scheduled to take effect in June.

DOJ’s Legal Argument

The DOJ’s complaint, filed in a Colorado District Court, centers on the claim that the law violates the Equal Protection Clause of the Fourteenth Amendment. The department argues that the law’s reliance on demographics and statistical disparities to prove discrimination will force developers to distort AI outputs, effectively requiring them to discriminate based on race, sex, religion, and other protected characteristics.

"Because the law relies on demographics and 'statistical disparities' as evidence of discrimination, it will essentially require developers to distort an AI system's outputs and 'discriminate based on race, sex, religion and other protected characteristics,' a violation of the Fourteenth Amendment."

Administration’s Stance on AI Regulation

The DOJ’s intervention aligns with the Trump administration’s broader stance on AI regulation. In 2025, President Donald Trump signed executive orders as part of his "AI Action Plan," directing government agencies to avoid "ideological dogmas such as DEI" in AI tools. The administration has also pushed for a federal regulatory framework to override state-level AI laws.

The administration’s position reflects a commitment to maintaining "the United States' position as the global AI leader," a priority highlighted in the DOJ’s complaint.

Criticism of the DOJ’s Argument

Critics argue that the DOJ’s legal challenge and the administration’s broader approach to AI regulation are ideologically driven, ignoring the real-world impacts of discrimination in AI systems. The lawsuit underscores the ongoing debate over federal versus state oversight of emerging technologies.
