In this photo taken March 27, 2014, President Barack Obama meets with Pope Francis at the Vatican. Pope Francis’ highly anticipated visit to the White House next month will put on display his common cause with President Barack Obama on many issues. When he swept into office in 2008, Obama captured near rock-star status among millions who saw him as the embodiment of a new sense of social purpose. Now, that baton has largely passed to the outspoken Francis. (AP Photo/Pablo Martinez Monsivais)
