Sanctuary Penalty and Public Protection Act of 2025

This bill creates a federal database identifying state or local governments that conflict with immigration enforcement laws. It prohibits federal funding for any jurisdiction listed in this database, which includes entities that block cooperation with immigration detainers, restrict arrests of certain immigrants, or prevent officials from interviewing incarcerated individuals about immigration status. The database must be updated quarterly and made public within 90 days of the bill's enactment. This directly affects local governments that have policies limiting collaboration with federal immigration authorities.
