The US Department of Justice has joined forces with Elon Musk's xAI to challenge Colorado's AI anti-discrimination law, raising alarms about the federal government's stance on consumer protections in the age of artificial intelligence.
Federal Intervention in State AI Law
In April 2025, the Justice Department filed a lawsuit alongside xAI against Colorado's Senate Bill 205, which aimed to prevent discrimination in high-risk AI systems used for hiring, housing, and healthcare. This marks the first time the federal government has intervened in a lawsuit challenging a state AI law.
The lawsuit is part of a broader federal effort to reframe AI consumer protections as ideological overreach. In July 2025, President Donald Trump signed an executive order on 'preventing woke AI,' which equated bias mitigation measures to a leftist agenda. The National Policy Framework launched in March included a push to pre-empt state AI laws, with Colorado's law specifically targeted.
The Colorado AI Bill
Senate Bill 205 originally required bias audits, impact assessments, and disclosure for high-risk AI systems. After pushback from the business community, Colorado revised the requirements in mid-March, reducing the transparency framework before xAI filed its lawsuit.
State Representative Brianna Titone, one of the bill's sponsors, dismissed xAI's claims that the law would force companies to promote ideological views. 'SB 205 is about consequential decisions... We're not restricting speech. Our bill does not say that Grok still can't be a dick,' she said.
Arguments Against the Law
The Justice Department argued that the law constituted 'state-mandated discrimination,' obligating AI developers to discriminate by altering models that use 'neutral criteria.' However, research shows that seemingly neutral criteria can produce worse outcomes for marginalized groups. A 2019 study in Science found that a healthcare algorithm used 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.
Similarly, bias can enter AI systems when models have less training data on certain groups, leading to worse performance. Improving representation in training data has been shown to nearly eliminate performance discrepancies.
Impact on Businesses
Critics, including the Wall Street Journal, argued that the law could kill the entrepreneurial spirit. However, no companies have cited the law as a reason for leaving Colorado. Governor Jared Polis stated that 'far more' firms are moving to Colorado than leaving. The only concrete example offered was Palantir, which mentioned the bill as a possible burden in an SEC filing but did not say it was the reason for leaving Colorado for Florida.
On the other hand, companies like Microsoft have flagged AI bias and discrimination as a material risk. Small businesses have legitimate concerns, but using AI for consequential decisions without checking for discrimination is irresponsible.
The Outcome
On 14 May, Governor Polis signed into law a new bill, SB 189, which repeals and replaces SB 205. The new law removes requirements for proactive bias assessments, annual reviews, and reporting of discrimination to the state. Instead, it requires AI developers to share technical documentation with deployers (but not the public) and gives consumers the right to request human review after an AI-involved decision.
This watered-down version falls short of ensuring meaningful accountability for high-risk AI systems, according to critics.
Broader Implications
The Justice Department's involvement sends a clear message to other states considering AI consumer protections: don't try. This federal pre-emption, combined with billionaire influence, threatens to undermine efforts to shield residents from AI harms in the absence of federal regulation.
Dr Genevieve Smith, a postdoctoral research fellow at Stanford University and founder of the Responsible AI Initiative at UC Berkeley, argues that 'AI is an incredibly powerful technology, and its potential is greatest when it works for all of us. We deserve the transparency and protection to get there.'
