Mijente, the Immigrant Defense Project (IDP), CUNY Law School’s Human Rights and Gender Justice Clinic (HRGJ) and the Center for Constitutional Rights have filed a Freedom of Information Act (FOIA) request to demand information on contracts between Immigration and Customs Enforcement (ICE) and Department of Homeland Security (DHS) and commercial information technology and data service providers RELX Group and Thomson Reuters. The request follows documentation and reporting on the role of the “data broker firms” in providing information that is used by U.S. government agencies in immigration enforcement operations.
