How could Cook County's data sharing restrictions affect Tom Dart's office?
Cook County data limits may change how Sheriff Tom Dart accesses records The proposed Cook County amendment aims to prevent private companies contracted by the county from selling or sharing personal data with third parties, including U.S. Immigration and Customs Enforcement. Since the Sheriff's office handles data related to court and jail records, this restriction could force changes in how the office and its vendors manage and provide information to immigration enforcement agents. The measure, if passed, would close loopholes that previously allowed ICE access to county data through these contractors, though it specifically excludes cases involving a criminal warrant or court order.

How it reaches Tom Dart
-
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.
The full event1independent outlet -
Because the Sheriff's office manages data related to jail and court records, the restriction on county contractors sharing data with ICE would require the office to adjust its operational procedures and data access methods to comply with the new county standards.

Why it matters
For the Cook County Sheriff's office, this legislation represents a shift in how sensitive resident data is managed and shared with federal immigration authorities. While the measure aims to protect residents' data from surveillance, it necessitates operational changes to ensure compliance, particularly regarding the data held in jail and court systems.
The push for this legislation is part of a wider grassroots 'No Tech for ICE' campaign, which immigrant advocacy groups have been promoting for over four years. The county's stand is viewed by advocates as an example that other jurisdictions should follow to protect county data from 'getting into the wrong hands.'
