San Diego, introduced a bill Thursday that would make it harder for local law enforcement in California to resist cooperating with immigration authorities. On Friday, Jones was in downtown San Diego promoting his proposed changes to the state’s so-called sanctuary law as a group of nearby demonstrators loudly voiced their opposition.

California has long been considered a sanctuary for all, especially immigrants and their families. But a group of Republican lawmakers believe certain laws protecting these communities have gone too far.

The proposed law, SB 554, is titled “Safety Before Criminal Sanctuary,” and is a direct response to a policy passed by the San Diego County Board of Supervisors last December.
