Newly installed Pope Leo XIV will hold a Mass with cardinals in the Sistine Chapel, a day after he was elected as the surprise choice to be the leader of the Catholic Church, becoming the first U.S. pontiff.

With no candidate securing the necessary two-thirds majority, or 89 votes, the world will need to wait longer for a new leader of the Catholic Church
