Immigration Detention: Actions Needed to Improve Planning, Documentation, and Oversight of Detention Facility Contracts, Report to the Chairman Committee on Homeland Security House of Representatives [open pdf - 2MB]
From the Highlights: "The Department of Homeland Security's ICE [U.S. Immigration and Customs Enforcement] detained approximately 48,500 foreign nationals a day, on average, for 72 hours or more in fiscal year 2019. ICE was appropriated about $3.14 billion in fiscal year 2020 to operate the immigration detention system. ICE has three ways of acquiring detention space--IGSAs [intergovernmental service agreements] with state or local government entities; agreements with Department of Justice U.S. Marshals Service to join an existing contract or agreement (known as a 'rider'); or contracts. This report examines (1) what data show about the characteristics of contracts and agreements; (2) the extent to which ICE developed and implemented processes and a strategic approach to acquire space; and (3) the extent to which ICE has overseen and enforced contracts and agreements."
