Cardinal Robert Francis Prevost, recently chosen as the first American pope, was elected following four rounds of voting in the papal conclave. His election was confirmed on Thursday with the traditional appearance of white smoke from the Sistine Chapel. The ceremony, which will take place ten days after his election, is expected to draw numerous world leaders to the Vatican.
