Let me tell you what is interesting about the administration. We had Central American miners that were placed in Ohio, and we never knew a thing about it. We didn't know where they were. And, in fact, we know now that some of them, there is a case going on where some of them may have been human-trafficked.

[President] needs to engage them in a very personal way. And he needs to tell them that this is something that America, the United States of America, needs. Not Republican. It's not Democrat. It's America.
