The Department of Defense is preparing to send 5,000 troops to the U.S. border as a caravan of some 7,000 migrants walks its way north through Mexico, bent on entering the country and demanding asylum. Officials announced the new, beefier force on Monday, which is up from the 800 troops previously planned. That would be in addition to 2,000 National Guardsmen President Trump deployed to the border back in April. The troops, who would be forbidden from engaging in law enforcement actions on U.S. soil, would be there to provide support to border patrol officials and law enforcement. The White House is also said to be planning a total border shutdown on Oct. 25.
