WASHINGTON (AP) — President Donald Trump urged congressional Democrats to fund his long-promised border wall in a somber televised address that was heavy with dark immigration rhetoric but offered little in the way of concessions or new ideas to break the standoff that has left large swaths of the government shuttered for 19 days.

Speaking to the nation from the Oval Office for the first time, Trump argued Tuesday night that the wall was needed to resolve a security and humanitarian “crisis,” blaming illegal immigration for what he said was a scourge of drugs and violence in the U.S. and asking: “How much more American blood must we shed before Congress does its job?”

Democrats in response accused Trump appealing to “fear, not facts” and manufacturing a border crisis for political gain.

Using the formal trappings of the White House, Trump hoped to gain the upper hand in the standoff over his demand for $5.7 billion to build a wall along the U.S.-Mexico border. He plans a visit to the border Thursday as he continues to pitch what was a signature promise of his 2016 presidential campaign.
