PRI's The World: 12/24/2015

On this Christmas Eve edition of The World, we hear about how an American woman and her Iranian husband bring together their family for a halal Christmas dinner. We also have a story about a chance meeting in a World War Two Japanese internment camp: Two boys who would later become leaders in Washington, Alan Simpson and Norman Mineta, talk about injustice and friendship. Plus, we'll hear how the North Pole became part of the Christmas tradition, and why Halifax, Nova Scotia sends a giant Christmas tree to Boston every year.
