Be careful about anybody who's running for president who's going to tell you that they're going to build a wall across the entire southern border. It's not going to happen. It is the wrong message to send. And it's not going to be effective.
I know the human spirit. I haven't found a wall that can be built that a determined human being can't get over, under or around.
That has always been the underpinning of his [Donald Trump's] policy along with the building of the wall on the United States-Mexican border. And those things have remained completely consistent.
