Mexico is ramping up security along its borders as the Trump administration pressures the country to halt a growing caravan of mostly Honduran immigrants. President Trump has threatened to shut down that border with national guard troops to keep thousands of immigrants from entering the U.S. Mexican officials are asking the UN High Commissioner for Refugees to help identify "legitimate" asylum claims from the migrants. A top Mexican official told Fox News the migrants with rejected asylum claims would be immediately sent back to their home countries.
