This week two key global figures are visiting the U.S. and will be making a lot of news. Pope Francis is visiting Washington, where he met with President Obama at the White House, New York, where he will address the United Nations, and Philadelphia for the World Meeting of Families. President Xi Jinping is embarking on his first state visit to the United States this week. He met with business leaders in Seattle, will have a formal state dinner at the White House, and will address the UN in New York. Pope Francis is expected to be political during his trip while President Xi's visit is coming at a time when economic and security issues with China are hot topics. Whose visit is more important?
