From the April 20 edition of Fox News' The Kelly File:
MEGYN KELLY (HOST): Dr. Ben Carson joins us now. The 2? The 2 is like the -- nobody -- the 2? What?
BEN CARSON: The point being we have lots of options here. We can have a $200 bill, but, you know, Andrew Jackson was the last president who actually eliminated the national debt. That's no small feat here.
KELLY: But he had slaves.
CARSON: We also had the possibility of putting one person on the front of the bill and one on the back of the bill.
KELLY: That's what's happening. He's moving to the back. She's moving to the front.
CARSON: It doesn't matter who's on the front or who's on the back, but the point being, that would be very symbolic, because, you know, Harriet Tubman was a slave, herself. Andrew Jackson was a slave owner. And to give them equality like that, I think would be a great symbol.
KELLY: You know, Greta was suggesting earlier we should create a new bill. Why don't we have a $25 bill? Everybody wins. What do you think of that?
CARSON: That's a good possibility, too. We have lots of possibilities, all kinds of things we can do. But, you know, as you can imagine, there will come a time when we won't have currency at all. I don't think it's all that far into the future.
