Mattis to travel US-Mexican border on Wednesday look plight on migrant caravan

U.S. Defense Secretary Jim Mattis said he would travel to the border with Mexico on Wednesday following the deployment of thousands of troops to bolster President Donald Trump's efforts to crack down on illegal immigration.

"I'll visit the border tomorrow," Mattis said before the start of his meeting with his Qatari counterpart. There are more than 5,000 active-duty U.S. troops on the border with Mexico in support of Customs and Border Protection (CBP).
