Rebuilding the Gulf Coast; Karen Armstrong; Remembering George Crile

Guest host Walter Isaacson holds discussions about the recovery effort on the Gulf Coast after Katrina—first with Alphonso Jackson and Don Powell, then with Mary Landrieu. Religious scholar Karen Armstrong talks with guest host Rev. Peter Gomes about her new book, "The Great Transformation: The Beginning of Our Religious Traditions." We remember journalist George Crile with excerpts from appearances on the show.
