(CNSNews.com) – “We are building a wall on the southern border, which is absolutely necessary,” President Trump told a rally in Phoenix Tuesday night.

The crowd erupted in chants of “built that wall.”

“Build that wall,” Trump continued:

Now the obstructionist Democrats would like us not to do it, but believe me, if we have to close down our government, we’re building that wall. Let me be very clear to Democrats in Congress, who oppose a border wall and stand in the way of border security — you are putting all of America’s safety at risk. You’re doing that. You’re doing that.

Again, the Border Patrol today, I said, how important is the wall to some of the folks? I met with a lot of them. And they looked at me, they said, ‘It’s vital.” It’s vital. It’s so vital.’ And you know, we have walls — I don’t know if you know, we’re already starting to fix a lot of the walls we already have. ‘Cause we don’t have to rebuild them. And we want walls that you can see through in a sense, you want to see what’s on the other side. But we’re starting to fix a lot of walls, we’ve done a lot of work.

But I said to them, How are we doing and how important are the walls? And they said, ‘Mr. President, you have no idea. It is desperately needed.’ We’re going to have our wall, we’re going to get our wall.

And that wall is also going to help us, very importantly, with the drug problem and the massive amounts of drugs that are pouring across the southern border. My administration will never back down in demanding immigration control. The American people voted for immigration control. That’s one of the reasons I’m here. And that is what the American people deserve and they are going to get it. So you put pressure but believe me, one way or the other, we’re going to get that wall.
