Trump pledges asylum crackdown, tent cities; is it legal?

WASHINGTON — President Donald Trump said Thursday he plans to sign an order next week that could lead to the large-scale detention of migrants crossing the southern border and bar anyone caught crossing illegally from claiming asylum — two legally dubious proposals that mark his latest election-season barrage against illegal immigration.

Trump also said he had told the U.S. military mobilizing at the southwest border that if U.S. troops face rock-throwing migrants, they should react as though the rocks were "rifles."
