Prevost was brought to the Vatican in 2023 by Pope Francis as the powerful head of the office that vets bishop nominations.

Cardinal Robert Prevost may be the first person from the U.S. to become the head of the Catholic Church but his surprising election by the world's cardinals as Pope Leo XIV probably had less to do with his birthplace than his former workplace.

Cardinal Robert Francis Prevost – now known as Pope Leo XIV — is the first pope from the United States. The 69-year-old from Chicago is known as a leader with global experience. He spent much of his career as a missionary in South America and most recently led a powerful Vatican office for bishop appointments.
