CHRIS WALLACE, FOX NEWS: Charles, it seems to me that Trump was taking quite a risk today holding this meeting with the Mexican President with so little preparation. Pena Nieto could have roasted him, but in fact, it was respectful, it was diplomatic, and it put Trump on the international stage. Do you think it will help him?
CHARLES KRAUTHAMMER: Yes. He took a risk and he pulled it off. Look, the big negative about Trump, the thing that the Clinton campaign plays on, is the fact that it's hard to imagine him as president. Being presidential is a thing he's been trying to do. His staff has been trying to get from him for the last six months.
Now here he is, standing on the world stage, with a world leader. This is a big step. He not only held his own, I think in some ways he sort of dominated. The Mexican President was rather defensive, asking for respect. Trump, I thought, spoke well. And then if you noticed at the very end when they took questions, it was Trump who took charge. He is sitting in the palace of the president of Mexico. This never happens. Normally, it's the host who picks the journalists. Trump took charge, naturally, walked off the stage as the dominant guy. He pulled it off. I think he really helped himself.
