Pope Leo XIV, the first American pontiff, gave his first homily from the Sistine Chapel on Friday in a move that could signify how he intends to lead the Catholic Church.

Speakers blasted “Born in the U.S.A. and ”American Pie" as six cardinal electors from the United States celebrated the first U.S. pope a day after Chicago-born Cardinal Robert Prevost became Pope Leo XIV.

John Prevost told "CBS Mornings" he found out his brother was the next pope with everyone else – after hearing his name announced on the balcony of St. Peter's Basilica on TV.
