NBC News special anchor Maria Shriver talks about the "People's Pope" and the excitement surrounding the 2015 Papal visit to Washington, DC, New York and Philadelphia. Millions of people are expected to line the streets of Washington, New York, and Philadelphia to catch a glimpse of Pope Francis during his six-day trip to the United States. Shriver analyzes the roots of the "rock star" pope's wide appeal to Catholics and non-Catholics alike and talks to Andrew McKeough at Villanova University about what makes Pope Francis stand out and what he's doing to be that people's Pope.
