ICE agents stand guard outside a immigrant detention center in Newark, New Jersey in May 2026. Medicaid officials improperly shared data about millions of people with ICE, who then shared that data with the data analytics firm Palantir, according to new court filings.

The revelations came out in a federal court case brought by Democratic states challenging ICE’s access to Medicaid data to aid in deportation efforts.
