In April, the US Department of Justice joined Elon Musk’s xAI in suing Colorado over its Artificial Intelligence anti-discrimination law, escalating a clash over how states can regulate high-risk automated systems. The dispute centers on Senate Bill 205, a measure aimed at reducing discrimination in consequential decisions such as hiring, housing, and healthcare. The law originally required bias audits, impact assessments, and disclosure, but Colorado revised those provisions in mid-March after business pushback and adopted a reduced transparency framework before xAI filed suit.
The federal challenge is presented as part of a broader campaign to portray Artificial Intelligence consumer protections as ideological overreach. In July 2025, Donald Trump signed an executive order on “preventing woke AI”, framing bias mitigation as a political agenda. A federal National Policy Framework launched in March also included a push to pre-empt state Artificial Intelligence laws, with Colorado’s law singled out. The justice department’s intervention in Colorado marks the first time the federal government has sought to intervene in a lawsuit challenging a state Artificial Intelligence law.
The case turns on whether anti-bias rules distort supposedly neutral systems. xAI argued the Colorado law would force the company to advance the state’s “ideological views on various matters, racial justice in particular”, including in its Grok chatbot. The justice department described the law as “state-mandated discrimination” that “obligates AI developers and deployers to discriminate”. Opponents of that position argue that apparently neutral criteria can still generate unequal outcomes. A 2019 study published in Science found that a widely used healthcare algorithm deployed across US hospitals assigned Black patients half the care of equally sick white patients because it used healthcare costs as a proxy for health needs. Removing healthcare costs eliminated racial bias in the model and improved the system’s effectiveness.
The argument that anti-discrimination rules would undermine innovation is also disputed. No companies are cited as leaving Colorado because of this regulation. Jared Polis said that “far more” firms are moving to Colorado than leaving. Palantir cited the bill as a possible burden in a Securities and Exchange Commission (SEC) filing, but did not say it moved to Florida because of the measure. At the same time, companies including Microsoft have identified bias and discrimination in Artificial Intelligence as a material risk, underscoring the commercial and legal stakes of weak oversight.
The political campaign ultimately reshaped the law. On 14 May, Polis signed a new bill, SB 189, which repeals and replaces SB 205. The new measure removes requirements for proactive bias assessments, annual reviews, reporting discovered discrimination to the state, and using reasonable care to address known and foreseeable harms. What remains is a requirement for developers to provide technical documentation to deployers, along with notice to consumers that Artificial Intelligence was involved in a decision and a right to request human review. The result preserves some transparency while falling short of proactive accountability for high-risk systems.
