Warren hosted Senator John McCain and then Senator Barack Obama at The Saddleback Church for a forum on faith and then went on to offer the invocation at President Obama's inauguration. His book 'A Purpose Driven Life' sold over 25 million copies world wide and has now been republished in an expanded version.
