WHITFIELD: All right. Right now Pope Francis is on the second full day of his historic trip to Mexico. A short time ago, tens of thousands of people joined the Pope for mass in a notoriously dangerous suburb just outside of Mexico City. The Pope is also visiting a children's hospital this afternoon. Let's bring in CNN correspondent Shasta Darlington who was in Mexico City for it. So Shasta, what's the significance of today's mass?</s>SHASTA DARLINGTON, CNN INTERNATIONAL CORRESPONDENT: Well, Fredricka, to start with, it was surprisingly political. Pope Francis lashed out what he called the temptations of health, fame and power. He got emotional when he told parishioners you can't dialogue with the devil because he always wins. But it was in the final angelus but he was very direct and he said, you know, listen, we need to be building a Mexico of opportunity, not one that destroys its young people in a reference to immigration and drug wars. Take a listen to this.</s>POPE FRANCIS, CATHOLIC CHURCH LEADER (through translator): I want to invite you today, again, to be on the front line to be the first in all initiatives that help make this blessed land of Mexico a land of opportunities where there will be no need to emigrate in order to dream, no need to be exploited in order to work.</s>DARLINGTON: His message certainly went down well with the people at the sermon.</s>WHITFIELD: What an incredible journey for everyone involved there. All right, Shasta Darlington, thank you so much. The next hour of CNN NEWSROOM begins right now.</s>WHITFIELD: Happening now in the</s>NEWSROOM. JUSTICE ANTONIN SCALIA, SUPREME COURT: I, Antonin Scalia, do solemnly swear --.</s>WHITFIELD: Remembering Supreme Court justice Antonin Scalia.
