In this program we revisit a 2007 conversation with evangelical leaders Rick and Kay Warren — exploring where they came from and what motivates them. Rick Warren hosted the first post-primary joint appearance of Barack Obama and John McCain at his Saddleback Church in southern California, one of the largest churches in the U.S. This two hour event, broadcast live on CNN, is just one sign of the cross-cultural authority he and Kay have achieved in a handful of years.
