The Trump administration will begin to draw down the nearly 6,000 troops stationed at the U.S.-Mexico border as early as this week, with all active-duty military expected to leave their stations within a month. In the run-up to the midterm elections, President Trump deployed military troops to the border to protect against what he called an “invasion” of Central American migrants, at one point suggesting he could send up to 15,000 troops. Defense Secretary Jim Mattis visited soldiers last week and admitted there was no clear long-term plan for the military deployment.
