 Thousands have gathered outside Philadelphia's Independence Hall, waiting for Pope Francis to speak later this hour. Earlier today, Pope celebrated Mass at the Cathedral Basilica of Saints Peter and Paul. Among the some 1600 congregants * this morning were organizers of the Vatican-sponsored World Meetings of Families which is what prompted the Pope to plan his US trip in the first place. NPR's Jeff Brady is in Philadelphia. From most of the last week, the catholic church has held his triennial World Meeting of Families in Philadelphia. That already attracted thousands of people. Now much of the downtown has been closed to traffic for events involving Pope Francis over the next two days. He's scheduled to be at Independent's National Historical park to talk about immigration and religious freedom. This evening, Francis is expected to parade through downtown before giving a speech at a big open-area event that also includes entertainment. Tomorrow Pope visits a prison then meets with bishops at a local seminary. He'll hold a large Mass outside the Philadelphia Museum of Art before heading back to Rome Sunday evening.
