BRIAN KILMEADE (CO-HOST): Mexico may be getting the message that the president will fulfill this promise to shut down the border unless something is done. However, the ramifications would be tremendous. You have $1.7 billion worth of services flowing back and forth daily. The auto industry would be probably crippled in about a week. If you have 12 straight days, both countries could be put into a recession. But the president is trying to say, security over economics any day. My main job is to keep us safe. And right now this border is not safe. 

STEVE DOOCY (CO-HOST): Well, and in that sound bite we just played with the president in the Oval Office, he said of Mexico, “Let's see what they do.” So in other words, this is -- it's almost like he's negotiating again. He says, “Unless Mexico does something to stop the surge of people across our southern border, I'm going to close, I'm going to close our border.” Of course, behind the scenes at the White House apparently they're talking about a plan B which would close the border to everything except commercial traffic, so that trucks and trains could continue to bring auto parts through, all sorts of things back and forth. We would not have, much to the horror of many people, an avocado shortage in four days.
