The Oval Office meeting this past March began, as so many had, with President Trump fuming about migrants. But this time he had a solution. As White House advisers listened astonished, he ordered them to shut down the entire 2,000-mile border with Mexico — by noon the next day.
The advisers feared the president’s edict would trap American tourists in Mexico, strand children at schools on both sides of the border and create an economic meltdown in two countries. Yet they also knew how much the president’s zeal to stop immigration had sent him lurching for solutions, one more extreme than the next.
