Trump also threatened to close the U.S.-Mexico border. He spoke to reporters Friday.

President Donald Trump: “We have right now two big caravans coming up from Guatemala, massive caravans, walking right through Mexico. So, Mexico is tough. They can stop them, but they chose not to. Now, are they going to stop them? And if they don’t stop them, we’re closing the border.”

Mexico’s Foreign Secretary Marcelo Ebrard responded to the news by tweeting, “Mexico doesn’t act based on threats.” Residents and workers on both sides of the U.S.-Mexico border have blasted Trump’s announcement, warning it would cause massive disruptions to trade and daily life.
