WASHINGTON — President Donald Trump said Sunday that he might declare a national emergency imminently to secure money for his border wall. "I may declare a national emergency dependent on what's going to happen over the next few days," Trump told reporters as he left the White House for Camp David. A White House official told CNN link on Saturday that Trump was leaning towards declaring a national emergency to use military funding for his wall. Trump has demanded Congress appropriate money for the wall, and his dispute with Democrats over the issue pushed the government into an ongoing partial shutdown. Vice President Mike Pence was scheduled to meet with congressional leadership staff on Sunday afternoon, where, according to two congressional sources, aides would be given the White House's budget justification for about $5.7 billion for the border wall.
