Mourners from around the world are set to gather Friday for Billy Graham's "last crusade." Graham was revered as "America's pastor" for more than six decades. He counseled nearly every U.S. president since Harry Truman. Graham preached his brand of evangelical Christianity to millions at events he called crusades. He became one of America's first TV mega pastors. He died last week at age 99 at his home in Montreat. The private funeral service will be streamed live.
