Existing law generally prohibits law enforcement from providing information regarding the release date of an individual from custody or from transferring an individual to immigration authorities without a warrant or judicial probable cause determination.

This bill, the California Secure Borders Act of 2025, would state the intent of the Legislature to combat illegal immigration and secure the border by repealing those provisions, prohibiting the use of state funds for various welfare, health, housing, and other services for undocumented immigrants, requiring public disclosure of information on the impact of illegal immigration on crime rates and state and local services, providing cross-deputization training for local law enforcement to support federal border security actions, and providing standards for deployment of the State Guard to the border.
