Illinois Governor Blocks Federal Access to Autism Data
Illinois Governor JB Pritzker signed an executive order Wednesday prohibiting state agencies from sharing autism-related personal data with federal authorities, directly challenging Health and Human Services Secretary Robert F. Kennedy Jr.’s controversial plans for a national autism registry. The action represents one of the most significant state-level pushbacks against a Trump administration policy initiative since the president’s inauguration in January.
Pritzker’s order comes amid growing concerns about both the scientific basis and privacy implications of Kennedy’s proposed data collection efforts, which the HHS secretary describes as part of an investigation into the “root causes” of autism.

Protecting Privacy and Autonomy
The executive order explicitly prohibits Illinois state agencies from collecting or disclosing personally identifiable autism-related data unless required for direct care, legal compliance, or program eligibility. According to MSNBC, the protections extend to contractors, vendors, and grantees working with state agencies, who must also refrain from collecting, storing, or disclosing such information.
“Every Illinoisan deserves dignity, privacy, and the freedom to live without fear of surveillance or discrimination,” Pritzker stated in a news release announcing the order. “As Donald Trump and DOGE threaten these freedoms, we are taking steps to ensure that our state remains a leader in protecting the rights of individuals with autism and all people with disabilities.”
The order requires that any legally mandated disclosures be limited to the minimum necessary information and anonymized wherever practicable, establishing a higher standard of privacy protection than currently exists at the federal level.
Conflicting Federal Messages on Registry Plans
Kennedy’s registry proposal has generated significant controversy, with HHS officials offering seemingly contradictory messages about its implementation. While department officials have denied plans for an autism registry, Kennedy himself reaffirmed on Monday that the plan remains in effect but characterized it as “voluntary” for participants.
Kennedy has faced sustained criticism from medical professionals, disability advocates, and civil liberties groups for his public statements regarding autism, including his recent comments broadly characterizing people with autism as incapable of leading normal lives. Medical experts note that the “root causes” Kennedy seeks to investigate are already well-established in scientific literature.
The HHS secretary’s history of promoting unsubstantiated theories regarding vaccines and autism has further intensified scrutiny of the registry proposal, with critics suggesting it could reinforce harmful misconceptions about autism spectrum disorders.
Model for Democratic State Resistance
Pritzker’s action positions Illinois as a potential model for other Democratic-led states considering how to respond to controversial federal initiatives. The governor has increasingly established himself as among the state executives most willing to directly challenge Trump administration policies that conflict with progressive priorities.
In April, Pritzker gained national attention for criticizing “do-nothing Democrats” who “want to blame our losses on our defense of Black people and trans kids and immigrants, instead of their own lack of guts and gumption,” signaling his willingness to take more confrontational approaches to opposing the administration.
Political analysts suggest Pritzker’s executive order could inspire similar actions in other blue states concerned about federal data collection efforts, potentially creating a patchwork of state-level privacy protections that complicate implementation of nationwide programs.

Broader Implications for Federal-State Relations
The executive order highlights evolving tensions between state and federal authorities in areas of healthcare policy and data privacy. Under the U.S. federal system, states retain significant authority to establish their own policies regarding the collection and sharing of certain types of information, potentially creating jurisdictional conflicts when federal agencies seek access to that data.
Legal experts note that while federal authorities may attempt to challenge such state-level restrictions, the practical effect is often to make national data collection efforts more difficult and potentially less comprehensive. This dynamic may influence the implementation of other data-intensive federal initiatives in coming months.
Kennedy has not yet publicly responded to Illinois’ action, though HHS officials have previously emphasized their commitment to protecting Americans’ privacy in any data collection efforts. The registry controversy reflects broader debates about balancing public health research objectives with privacy rights and protections against potential discrimination.
