The Trump administration on Monday, Oct. 29, 2018, announced plans to deploy 5,200 active duty troops, double the 2,000 who are in Syria fighting the Islamic State group, to the border to help stave off the caravans. The main caravan, still in southern Mexico, was continuing to melt away, from the original 7,000 to about 4,000, as a smaller group apparently hoped to join it.
