(CNN) - Under ordinary circumstances, Donald Trump and Rupert Murdoch are probably not in the habit of attending the birthday parties of elderly Christian preachers in the North Carolina mountains.
But they were both among the hundreds of well-wishers at the party on Thursday marking Billy Graham’s 95th birthday.
Graham spent his career leading revivals around the globe, following a long tradition of evangelists who have traveled far and wide to urge sinners to accept Christ. But his birthday guest list shows that he is no ordinary preacher. He is a cultural icon, the most famous face of traditional Protestant Christianity.
“We need Billy Graham's message to be heard, I think, today more than ever," former vice-presidential candidate Sarah Palin told the crowd.
