2025.07.01 Complaint - State of California v. U.S. Department of Health and Human Services

The California Attorney General, leading a multistate coalition, filed suit against HHS and DHS after HHS' Centers for Medicare & Medicaid Services shared state Medicaid data files, which contain personal health records representing millions of individuals, with DHS and DOGE. The coalition alleges that this information-sharing violates privacy and other federal laws. Plaintiffs ask the court to declare the data transfer unlawful; to enjoin HHS from transferring further data; to enjoin DHS or any other federal agency from using the data for immigration enforcement or surveillance; and to order the destruction of all data already disclosed to DHS and DOGE. State of California v. U.S. Department of Health and Human Services, No. 3:25-cv-05536 (N.D. Cal.).

2025.07.18 Reported: Trump administration hands over Medicaid recipients’ personal data, including addresses, to ICE - CNN

CNN reports that ICE will be granted access to personal data, including names, addresses, ethnicities, and Social Security numbers, of 79 million Medicaid enrollees under a secretive agreement with Centers for Medicare and Medicaid Services. Officials claim the goal is to prevent improper Medicaid use by undocumented immigrants, but the agreement confirms that "ICE will use the CMS data to allow ICE to receive identity and location information on aliens identified by ICE."

Subsequent Trump and Court Action

2025.08.12 Preliminary Injunction - State of California v. U.S. Department of Health and Human Services

A federal judge partially granted Plaintiff states' motion for a preliminary injunction against DHS and HHS. The court order blocks DHS from using Plaintiffs' Medicaid data for immigration-enforcement purposes, and blocks HHS from sharing Medicaid data obtained from Plaintiffs with DHS for those purposes. The order finds that the states will likely succeed on their claim that the federal government's actions abandoning its longstanding practice of not using Medicaid data for immigration enforcement violate the Administrative Procedure Act.

The preliminary injunction will remain in effect throughout the litigation, or until "14 days after both DHS and HHS have completed a reasoned decisionmaking process (or rulemaking, if necessary) that considers the matters discussed in this ruling, along with any other relevant policy tradeoffs or legal considerations." State of California v. U.S. Department of Health and Human Services, No. 3:25-cv-05536 (N.D. Cal.).
