This bill mandates the Secretary of Homeland Security and the Attorney General to jointly develop and maintain a publicly accessible database identifying "sanctuary jurisdictions." These jurisdictions are defined as state or local government entities with laws, regulations, policies, or practices that conflict with specific federal immigration statutes. Such policies include those that prohibit or restrict local law enforcement from complying with federal immigration detainers or from assisting in the arrest or detention of certain individuals. Furthermore, jurisdictions that prevent federal officials from interviewing incarcerated individuals to determine their immigration status or involvement in crime would be included. Once a state or local government entity is identified and listed in this database, it will be formally designated as a sanctuary jurisdiction . A key provision of this legislation is the prohibition on the obligation or expenditure of any federal funds to these designated jurisdictions. This measure aims to penalize jurisdictions that do not fully cooperate with federal immigration enforcement efforts by withholding federal financial support.
