Former N.J. Gov. Chris Christie responded to Jonathan Karl's interview with Rep. Alexandria Ocasio-Cortez on ABC's "This Week roundtable.
CHRIS CHRISTIE, ABC NEWS CONTRIBUTOR: I think she doesn't know how to do math, that's for certain.
JONATHAN KARL, ABC NEWS: What? In terms of the calculus on impeachment?
CHRISTIE: No, no, not on the calculus on impeachment, on what she was talking about at the end regarding billionaires and, you know, she wants everybody to have all of these things but she herself has been so off on the math of what these things cost and what it would take to tax those things and is it even possible to provide them. I mean, the fact of the matter is she is someone who's having a great experience at the moment. And it happens a lot in American politics.
KARL: It’s pretty extraordinary, though, to see a freshman come on the way she's come on.
STEFANIE BROWN JAMES, DEMOCRATIC STRATEGIST: Yes, absolutely. Well, and I think part of her popularity is that she's able to really talk about issues that everyday Americans face. Health care, education, equal pay. And so, you know, she --
KARL: But -- but when you --
BROWN JAMES: -- she's having a moment for sure. But she's also talking about very real issues that a lot of Democrats care about.
CHRISTIE: But no realism. But no realism attached to it.
BROWN JAMES: Not completely.
CHRISTIE: She wants tuition-free college, she wants $15 minimum wage for everybody, she wants health care for everybody. I mean, these are all things that -- that cost trillions of dollars and she has not once expressed a mathematically feasible way to pay for them. Now, that's OK when you're campaigning for something but now you have the office and you have a responsibility to do it. And if you’re going to have her on a show like this, she should be asked about how it works. And -- and she wasn't asked that this morning, Jon. And as long as she's not asked those questions, we’re going to continue to have her moment.
But at some point, you have to govern.
BROWN JAMES: No, but --
CHRISTIE: And she’s -- and she’s not governing. She’s -- she’s on a celebrity tour.
KARL: Well, she’s a freshman member who is very influential in where the caucus is going. That’s why we were talking to her. She is somebody who the 2020 candidates are lining up trying to get her endorsement.
BROWN JAMES: Yes, because she -- because she is speaking for Democrats and people who actually feel very left out of the process all across the country. She has a voice that represents a lot of people. And so I think it's important to have her on a platform like this, even though she is a freshman member, she may not be able to give specifics, but we cannot deny --
CHRISTIE: But she’s misleading those people that feel left out, Stefanie --
BROWN JAMES: That’s not misleading at all.
CHRISTIE: -- she’s misleading them because she’s telling them you can have tuition-free college, that you can have Medicare for All, and all those things.
BROWN JAMES: Which -- which many of the Democrats candidates are also saying the same thing.
KARL: Which by the way is the platform of many of the Democratic candidates.
CHRISTIE: But -- but -- but Jon, by the way, none of them have said how they’re going to pay for it.
