Donald Trump speaks with CNN's Anderson Cooper regarding his evolving position on immigration reform. "It is a process, you can't take 11 million people at one time and just say boom -- you're gone. We have to find where they ware, nobody even knows if it is 11 [million]."
TRUMP: Let me just tell you what my policy is, and I'm not going to go into all of it because we're doing a speech in a week on immigration which I think will explain it in even greater detail, but we're going to build a great wall.
The wall is going to be paid for by Mexico. People are not going to be able to tunnel because we are going to have tunnel technology. We're going to have all sorts of things on this wall. This is going to be a real wall.
Drugs will stop flowing into our nation and poisoning our youth and everybody else. We're going to have all sorts of E-Verify and everything you can think of in terms of immigration.
People will not come into our country illegally. We're going to fix that. We're going to make it so that like it's never been before. I don't know if you know, but Border Patrol agents, 16,500 Border Patrol agents endorsed Donald Trump. They've never done that for a presidential candidate before, because they're great people that want to do their jobs.
They don't want to stand there and watch people pour through our borders.
COOPER: The 11 million who are here.
TRUMP: Let me explain. We're going to build a wall. We are going to build a real wall, a wall that absolutely works. And they do absolutely work if it's done properly. Right now it's a joke. You have walls that are this high. That's number one.
We are going stop illegal immigration pouring into our country. My first day in office, I am going to notify law enforcement authorities that all of the bad dudes, and we have a lot of them, that are here illegally, that are the heads of gangs and drug cartels and all sorts of people…
COOPER: People who commit crimes.
TRUMP: And there are probably millions of them, but certainly hundreds of thousands. Big numbers. They're out. They're out. Excuse me, the police know who they are. I've spoken to many police. The police know who they are.
They deal with them all of the time. They're nothing but problems. We are going to end sanctuary cities. We are going to run a country like it's supposed to be run. We are going to have borders, very strong borders.
And after that, we're going to see what happens, but we are going to find people and we're getting immediately, and I mean first hour of my -- the first document I will sign will say, get the bad ones out of this country, bring them back where they came from.
Later in the interview, Trump noted that there will be no path to legalization unless illegal immigrants leave the country and come back.
