Trump says there's a "colossal surge" at the U.S.-Mexico border

The big picture: "Trump has become increasingly exasperated at his inability to do more to halt the swelling numbers of migrants entering the country," the AP reports. "There's not a lot they can do," he said in a statement on Friday, referring to U.S. troops stationed at what he described as an "emergency" on the southern border. "We're gonna bring up some more military."

The latest: On Saturday, President Donald Trump said there would be traffic and commercial delays along the southern border after his administration increased the number of immigration officers processing migrants attempting to enter the United States via Mexico until Mexico used its immigration laws "to stop illegals from coming through Mexico into the U.S., and removing them back to their country of origin."
