Vice President JD Vance is headed back to Vatican City for Pope Leo XIV's inaugural Mass, a week after the first American pope was selected.

Pope Leo XIV presided over his inaugural mass Sunday, May 18, with world leaders and a crowd of 200,000 people gathered in St. Peter’s Square at the Vatican. Following the death of Pope Francis on April 21, a conclave commenced May 7, bringing together a private group of cardinals tasked with voting for a new leader of the Roman Catholic Church.
