(CNN)House Speaker Paul Ryan on Friday gave a major boost to legislative efforts to preserve protections for young undocumented immigrants -- and urged President Donald Trump to not tear up the program. Trump told reporters Friday he was still mulling the decision. Responding to a question about Deferred Action for Childhood Arrivals, or DACA, on his hometown radio station WCLO in Janesville, Wisconsin, Ryan said Congress was working on a legislative fix to preserve the program. "I actually don't think he should do that," Ryan said of Trump's consideration of terminating the program. "I believe that this is something that Congress has to fix."
