President Donald Trump issued a dire warning to would-be immigrants making their way toward the U.S., warning that thousands of U.S. troops being sent to the border would return fire if caravan members throw rocks at them.Trump has already ordered thousands of troops to the southern border, and was asked after delivering a fiery speech at the White House whether he envisioned them firing on the people making there way approaching the border on foot. ‘I hope not. I hope not. It’s the military. I hope there won’t be that. But I will tell you this: Anybody throwing stones, rocks, like they did to Mexico and the Mexican military, Mexican police – where they badly hurt police and soldiers of Mexico – we will consider that a firearm,’ Trump warned.
