VATICAN CITY (AP) — Pope Leo XIV took his first popemobile ride through St. Peter’s Square ahead of his installation on Sunday, waving from the back of the open-back truck to the crowd waving flags and cheering “Viva il Papa!”

Were Princess Charlene, Queen Letizia, Queen Mathilde and Grand Duchess Maria Teresa allowed to wear white at Pope Leo XIV's inauguration mass? All about the royal rule!

Fierce Nigerian political rivals Peter Obi and President Bola Tinubu were seen laughing and joking at Pope Leo XIV's inaugural mass in Rome. Tinubu of the All Progressives Congress defeated Obi of the Labour Party in the heated and tightly contested 2023 presidential election - a victory Obi challenged at the Supreme Court without success.

The Vatican was already crowded with tourists and pilgrims on Saturday, but tens of thousands are expected on Sunday, and perhaps as many as 100,000 for Pope Leo's inaugural Mass, and Chicagoans have made the journey to Rome to represent their hometown pope.
