ICE improperly shared Medicaid data with analytics firm Palantir, which uses the information to identify noncitizens for deportation. The improper data-sharing was revealed through a federal court case filed by Democratic states challenging whether ICE should have access to the Medicaid database at all. The case signals that multiple states viewed the practice as a violation of data privacy protections for low-income households who rely on the program. Palantir's ELITE app integrates the Medicaid addresses directly into ICE agents' deportation targeting tools.
