<p>By Michael Hernandez</p> <p>WASHINGTON (AA) – President Donald Trump said Friday that America’s immigration system was overburdened, telling immigrants heading to the country’s southern border to turn around.</p> <p>"The system is full. When it's full, there's nothing you can do," Trump said while touring the U.S.-Mexico border as he continued to make the case for his long-promised border wall. "We've been trying to take people and we can't do it. You can't do it."</p> <p>"I’m sorry, we can't take you," he added. </p> <p>Trump claimed a national emergency along the U.S.'s southern border to obtain funds for the wall from previously made congressional appropriations after lawmakers repeatedly refused to provide him with the $5.7 billion in funding he had sought. </p> <p>He reiterated his claim of a border emergency Friday, saying "people want to come in. They shouldn't be coming in".</p> <p>"They're people that are causing problems. Gangs and more. We're getting them out. Stopping them for the most part," he said. </p> <p>The president has taken a hardline approach to both legal and illegal immigration since coming to office in 2017.</p> In addition to seeking to clamp down on migration from some Muslim-majority countries, he has cracked down on undocumented immigrants living in the U.S.
