Trump also pledged to deport up to 3 million undocumented people during an interview with “60 Minutes” that aired Sunday. This is “60 Minutes” correspondent Lesley Stahl.

Lesley Stahl: “Let’s go through very quickly some of the promises you made, and tell us if you’re going to do what you said—”

Donald Trump: “OK, sure.”

Lesley Stahl: “—or you’re going to change it in any way. Are you really going to build a wall?”

Donald Trump: “Yes.”

Lesley Stahl: “They’re talking about a fence in the Republican Congress. Would you accept a fence?”

Donald Trump: “For certain areas, I would. But certain areas, a wall is more appropriate. I’m very good at this. This is called construction. But a fence will be—”

Lesley Stahl: “So, part wall, part fence?”

Donald Trump: “Yeah, it could be—it could be some fencing.”

Lesley Stahl: “What about the pledge to deport millions and millions of undocumented immigrants?”

Donald Trump: “What we are going to do is get the people that are criminal and have criminal records, gang members, drug dealers—we have a lot of these people, probably 2 million, it could even be 3 million. We are getting them out of our country, or we’re going to incarcerate. But we’re getting them out of our country. They’re here illegally.”
