New York (CNN Business) Alec Baldwin's President Trump returned to NBC's "Saturday Night Live" after a few weeks away to declare a national emergency and explain why the country needs a wall on its southern border.

"I'm here to declare a very urgent, important national emergency," Baldwin as the President said. "This is a big one, so I don't want to waste any time, but first I'd like to blow my own horn."

Baldwin's Trump then said he'd just had a great health examination and was 6 feet, 7 inches tall, 185 pounds and "shredded." He then broke down why the country desperately needs the border wall.
