Supporters of Pope Leo XIV gathered Saturday, not in a cathedral or a church, but a baseball stadium the pope once frequented years as Robert Francis Prevost.

At an event celebrating the city's native son, Cardinal Blase Cupich spoke on immigration and the undocumented in his "Sermon on the Mound."
