Migrant caravan: 800 US troops could be sent to Mexico border - CNNPolitics
Defense Secretary James Mattis is expected to sign deployment orders as soon as Thursday that could send 800 or more troops to the border with Mexico to help border patrol authorities stop a caravan of migrants from Central America moving through Mexico to enter the US, according to three administration officials.
The officials tell CNN final details are being worked out including where the troops will come from and their specific tasks.
Several administration officials say it is anticipated that the Pentagon will pay for the bulk of the mission by using active duty troops. It's not yet clear if the Department of Homeland Security will reimburse the Pentagon.
