It may not seem that the president and the pope have much in common, but they share similarities. The United States' first African American president and the first Latin American pope both exploded onto the global stage sharing messages of hope and change.
President Obama's stop in Rome came amid a week-long trip to Europe and the Middle East during which the issue of Russia's incursions into Ukraine have been the key topic of discussion among world leaders.
Before Obama left the Vatican, he and the Pope shook hands and embraced.
"My family has to be with me on this journey. They've been very strong," Obama said. "Pray for them. I would appreciate it."
