Cook County proposes restricting data sharing with immigration enforcement
What happened
The Cook County Legislation and Intergovernmental Relations Committee passed an amendment on October 21, 2026, to limit information sharing with third parties, including U.S. Immigration and Customs Enforcement. The measure prohibits private companies with county contracts from selling or sharing personal information. If approved by the Cook County Board of Commissioners, the amendment would take effect in 60 days and close loopholes that allowed ICE access to certain county records.

Why it matters
The legislation aims to prevent county contractors from sharing personal information, such as license plate numbers, with third parties. This change would restrict access to court, jail, health, and Department of Motor Vehicles records for immigration enforcement agents, except when a criminal warrant or court order is involved.
Cook County's ban is currently being challenged by state law, prompting discussion on the viability of county-level restrictions.
