Pope Leo XIV, the first U.S. pope in history, addressed the crowd at the Vatican Thursday shortly after white smoke billowed from the roof.

On the second day of the conclave at the Vatican, the cardinal electors chose Chicago-born Cardinal Robert Prevost as the new pope, Leo XIV.

Pope Leo XIV may have broken a historic barrier by becoming the first pontiff from the United States, but his views on the Catholic Church could harken back to more traditional times. There are also some areas of the church's doctrine where he takes a more progressive stance, similar to his predecessor, Pope Francis.
