Sanctuary state: Gov. Jerry Brown signed legislation last week making California a “sanctuary state,” in a show of defiance against the Trump administration’s hardline immigration policies. Senate Bill 54, which is aimed at protecting the state’s estimated 2.3 million undocumented immigrants, dramatically limits the extent to which state and local law enforcement can cooperate with federal immigration authorities. The bill, which takes effect in January, bars officials from asking about people’s immigration status or from sharing information about them with federal immigration agents unless the individuals have been charged or convicted of a serious offense. Federal agents will still be able to enter county jails, but the acting director of U.S. Immigration and Customs Enforcement said that the bill would force the agency to conduct more large-scale raids on neighborhoods and workplaces to find undocumented immigrants.
