New Jersey lawmakers took a step forward Monday on legislation opposing President Donald Trump's immigration policies—which would use state funds to reimburse local governments for federal funds they may lose if they declare themselves sanctuary cities.

Sanctuary jurisdictions are defined as those that have declared that law enforcement officers within their borders will not cooperate with federal Immigrations and Customs Enforcement officers attempting to detain undocumented aliens.

At present there are 12 municipalities and three counties in New Jersey that have declared themselves to be sanctuaries.
