No idea. However Christie sure exposed Rubio as a lightweight robot.
All Christie showed in that exchange was how little he knew about Obama and his true agenda. Rubio had said that it was wrong for people to say Obama didn't know what he was doing - that he knew full well what he was doing: intentionally destroying the country. ie, "fundamentally transforming" it. If he did make an error it was in not fighting back harder to make that point clear.
