President Trump: I will say this: I have tremendous support within the Republican Party. If you look at Congress, you saw - with all of the numbers, you saw just a very small group of people voting. And it wasn't really against; it was a vote to open. It wasn't against. Because I think everybody agrees - frankly, the Democrats agree that you need border security. They agree that you need a barrier.I put out a quote this morning of Barack Obama; I put out a quote this morning of Hillary Clinton in 2015 - that was a few years ago - strongly saying that you need a border to keep illegals out. And that's what you have to have.

But it's not just illegals. It's criminals. It's drugs. It's the new phenomena that's been age-old, been going on for thousands of years, but it's never been worse than now because of the Internet. Human trafficking - where they grab women, put tape over their mouth, come through our border, and sell them. And they go both ways, in both directions. Now, they don't go through a port of entry. They'd be caught. But they go up where there's no wall. They make a right; they go to Mexico.

Look, we better get smart. Human trafficking is a big business. It's a big deal. DEALING IN CHILDREN IS A BIG DEAL. CHILDREN ARE probably THE MOST HARMED by not having the wall or its equivalent. But if you look at the human trafficking, they come in, they nab women, they grab them, they put tape over their mouth, they ties their hands, and they take them to another country, and they go right over that border. If we had a powerful wall, or its equivalent, they wouldn't be able to do it because they'd have to go through ports of entry.

Upon returning from Camp David, Trump explains he may declare National Emergency due to the drug/human trafficking "crisis". This would allow him to build the wall w/out Congressional Approval.

No, we're looking at a national emergency, because we have a national emergency. Just read the papers. We have a crisis at the border of drugs, of human beings being trafficked all over the world. They're coming through. And we have an absolute crisis, and of criminals and gang members coming through. It is national security. It's a national emergency....

It'll all work out. What we need is we need a strong border. We have criminals coming in. We have human traffickers coming in. We have drugs pouring in. We have things happening that you don't want to even know about. And it's been that way for decades, and we can't have it anymore.
