ROME — The new Chicago-raised Pope Leo XIV faces an immediate challenge in his native country: taming the brawling U.S. tribe of Catholics, riven by political divisions that have thwarted the will of his predecessors.

Prior to his election as Pope Leo XIV, Robert Prevost's social media activity suggested criticism of President Donald Trump's immigration policies.

Robert Francis Prevost, who was born in Chicago and attended Villanova University, was elected as the new pope on Thursday and chose Leo XIV as his papal name.
