President Donald Trump threatened to close large parts of the U.S.-Mexico border next week if America's southern neighbor does not "immediately" stop illegal immigration.
In a series of tweets Friday, the president wrote that he would shut down "the Border, or large sections of the Border," if Mexico does not "immediately stop ALL illegal immigration coming into the United States throug (sic) our Southern Border." He claimed closing off border crossings, key avenues for trade with a major partner, "would be a good thing!"
