'Deadly and unconstitutional': Trump attacks California sanctuary citiesA week after the Trump administration endorsed separating immigrant children from their parents as a deterrent against undocumented travel to the United States, Donald Trump convened a meeting of law enforcement officers and elected officials from California to blast sanctuary cities and depict immigrants as a violent threat. New sanctuary laws protecting immigrants went into effect in California in January. In a White House meeting that included the attorney general, Jeff Sessions, House the majority leader, Kevin McCarthy, and top officials from the department of homeland security and the US immigration and customs enforcement (Ice), Trump called the California policy “deadly and unconstitutional”.
