Lawmakers in California on Saturday passed “sanctuary state” legislation even as President Trump and his administration have vowed to crack down on jurisdictions that do not cooperate with federal immigration agents.

The bill approved early Saturday limits police cooperation with federal immigration authorities and is intended to bolster protections for illegal immigrants in the state.

But the acting director of the U.S. Immigration and Customs Enforcement on Saturday warned of “tragic consequences,” saying the policy “will make California communities less safe.”
