No Borders NewsIllinois Attorney General Kwame Raoul, joined by a multistate coalition, asked a U.S. district court to enforce a preliminary injunction that blocks U.S. Immigration and Customs Enforcement (ICE) from obtaining and using certain Medicaid recipient data.
In a court filing dated March 27, 2026, the coalition says it learned through communications with the U.S. Department of Health and Human Services (HHS) that HHS shared a “large and complex data set” of Medicaid information with ICE. The coalition argues this may have happened even though the court previously said much Medicaid data—including data about citizens and lawful permanent residents—is “off limits.”
The coalition says it does not yet know exactly what information was included in the shared data set. It is asking the court to confirm that the original order covers all people lawfully residing in the United States, and to require the federal government to explain what data was shared and how ICE used it.
Raoul said broad sharing of Medicaid data would violate privacy and could discourage eligible people—especially those who are most vulnerable—from enrolling in Medicaid. The filing also notes that Medicaid is a major health coverage program for low-income people, including children, pregnant women, people with disabilities, and seniors.
The motion is tied to an earlier lawsuit filed on July 1, 2025, in which the coalition challenged HHS’s mass transfer of Medicaid data to ICE for immigration enforcement. The court’s preliminary injunction allowed some transfers but blocked broader efforts to obtain sensitive health data, including data of people lawfully residing in the U.S., and data from other CMS-administered health programs.
