Private memorial service to follow at U.S. Naval Academy Chapel

A Private memorial service will take place for Sen. John McCain in the U.S. Naval Academy Chapel in Annapolis Maryland Sunday. The war hero was honored at a memorial service at the Washington National Cathedral Saturday. He was the 2008 Republican presidential nominee, but it's McCain's role as a legislator that may have most defined his public life.
