The U.S. Justice Department has joined xAI’s lawsuit against Colorado’s new artificial intelligence law, expanding Elon Musk’s legal dispute into a larger debate between federal and state governments over AI regulation.
The Justice Department entered the case on Friday, arguing that Colorado’s law violates the Fourteenth Amendment’s Equal Protection Clause.
The law requires AI companies to prevent unintentional discrimination but allows certain discrimination aimed at promoting diversity.
DOJ says Colorado’s AI law is unconstitutional
The Justice Department explained that Colorado’s law, SB24-205, bans algorithmic discrimination and sets rules for companies developing or using AI in important areas like mortgage lending, student admissions, and hiring.
The department’s press release said the law requires AI developers to follow disclosure, reporting, and prevention rules, but makes exceptions for algorithms meant to promote diversity or address past discrimination.
Assistant Attorney General Harmeet K. Dhillon from the Civil Rights Division strongly criticized the law, stating, “Laws that require AI companies to infect their products with woke DEI ideology are illegal.”
Brett A. Shumate, also an Assistant Attorney General, argued that “America’s success in the AI race” relies on removing obstacles to innovation and adoption, and said laws like Colorado’s could harm national and economic security.
xAI wants to block enforcement before June deadline
Reuters reported that xAI filed its lawsuit earlier this month in federal court in Colorado, seeking to block enforcement of the law before it takes effect on June 30.
The company argues that the statute violates the First Amendment by restricting how developers design AI systems and by compelling speech on contested public issues.
The law focuses on developers of “high-risk” AI systems used for decisions in employment, housing, education, healthcare, and financial services. These areas are important to the debate since automated systems can influence access to jobs, loans, medical care, and other key life opportunities.
Colorado declines to comment
The Colorado Attorney General’s Office declined to comment. The Justice Department’s move, however, significantly raises the stakes of the case.
What began as a lawsuit from Musk’s AI firm has now become a direct confrontation between the Trump administration and Colorado over whether states can impose their own rules on algorithmic discrimination.
The administration wants a single national law for artificial intelligence instead of letting each state make its own rules. This approach puts the federal government in conflict with states like Colorado, which have created their own AI laws while Congress debates national regulations.
A bigger test for AI regulation
This case could be a key test of how much power states have to regulate AI systems used in important decisions. Supporters say these laws are needed to protect people when AI affects jobs, housing, finance, education, and healthcare.
The Justice Department and xAI, however, argue that Colorado’s law is unconstitutional and could slow innovation.
For AI companies, this case is bigger than just Colorado’s law. If the law stands, other states might pass similar rules, leading to many different compliance requirements.
If xAI and the Justice Department win, states may be less able to regulate AI discrimination until a national law is created.
No matter the outcome, this lawsuit is becoming a major legal battle over who will set the rules for AI in the U.S.
