Donald Trump made a bit of presidential history by visiting the holy lands of Islam, Judaism and Christianity on his first overseas trip. He stayed on message but some say he fell a little short.
Despite criticism, the first lady's attire was in keeping with the protocol of the countries she visited and the precedent set by foreign leaders who have visited them.
The president made the remark after the pope presented him with a medallion featuring an olive branch. "I give this to you so that you can be an instrument of peace," the pope told him.
Wednesday's meeting, which focused on pursuing peace, comes a year after the pope suggested that Trump "is not Christian" because of his plan for a U.S-Mexico border wall.
NPR's Ari Shapiro interviews John Allen, editor of Crux, an independent news site, and president of Crux Catholic Media, about the meeting scheduled between the Pope and President Trump. Allen says despite their differences, they are not likely to have a contentious meeting. He says Trump will also meet with the Vatican's secretary of state and foreign minister for more substantive talks.
