The Trump administration is "drawing up plans" to halt immigration and customs processing at so-called "sanctuary cities," US Homeland Security Secretary Markwayne Mullin has said.

The cities, which are all run by Democrats, have refused to work with the White House in its crackdown on irregular immigration.

The plans would essentially halt all international passenger and cargo arrivals at major airports in Democratic states.
