Trump meets the Pope at the Vatican for a private audience - and gives him a set of Martin Luther King books - as he completes his tour of the world's three great religions

A lone American flag hung above the entryway to Pope Francis' apostolic palace in Vatican City as U.S. President Donald Trump arrived for the third leg of his tour of the world's great religions. Trump met Pope Francis on the fifth day of his first foreign presidential trip, after visiting the cradles of Islam and Judaism. Trump shook the Pontiff's hand and posed for photos in the Sala del Tronetto, the second-floor 'little throne room.' 'Thank you very much. This is such a great honor,' Trump was later heard saying as he and Francis sat across a desk from each other to begin their talks. Melania Trump and Ivanka Trump both wore black veils as a show of respect. 'What do you give him to eat?' the Pope asked Melania in Italian, referring to the president's hulking size.
