#3 "I would build a great wall, and nobody builds walls better than me, believe me, and I'll build them very inexpensively,"

"I will build a great, great wall on our southern border. And I will have Mexico pay for that wall."

"Mexico is not going to build it [a wall], we're going to build it. And it's going to be a serious wall. It's not going to be a toy wall like we have right now where cars and trucks drive over it loaded up with drugs and they sell the drugs in our country and then they go back and, you know, we get the drugs, they get the cash, okay, and that's not going to happen".
