From the March 7 edition of Fox News' The O'Reilly Factor:
BILL O'REILLY (HOST): Here is what I think has happened. Because I did the first interview with Trump when he announced that he was running for president back in June 2015. And he got a lot of attention with the wall thing. He got really a lot of attention with that, and then he said some harsh things about Mexicans coming into the United States causing crime and he built up fast a base. All right. And then he expanded the base into national security and he is going to stop Muslims from coming here temporarily and it built like this. And he did it all on emotion. And that's why when these stats come out and Americans see the incredible, incredible rise in immigrants in this country from 1970 to 2015, it resonates because there are people who are nativist. They don't want the immigrants here. And those people are all in Trump's camp.
