"By protecting criminals from immigration enforcement, cities and states with "so-called" sanctuary policies make their communities less safe and undermine the rule of law", Justice Department spokesman Devin O'Malley said in a statement after the ruling was announced.

As a presidential candidate, Trump pledged to ramp up deportations and build a wall along the U.S. -Mexico border.
