From breitbart.com:
Kentucky Sen. Rand Paul (R-KY)93% called for an end of “sanctuary city” policies after a Mexican illegal immigrant, shielded by city authorities from deportation, allegedly shot and killed 32-year-old Kathryn Steinle on Pier 14 in San Francisco.
As CNN notes, there is no strict legal definition of a “sanctuary city,” a term that advocates for mass immigration dislike for its revealing nature. The movement began thanks to American churches in the 1980s who welcomed illegal aliens from Central America purportedly fleeing violence from the Third World, much as they do today. Now, more than 200 state and local jurisdictions defy federal immigration law by refusing to detain illegal aliens who are usually caught in the commission of another crime for deportation.
