Republican presidential candidate Donald Trump speaks during a campaign rally in Kiawah, South Carolina, February 17, 2016. - Trump cannot claim to be a Christian, Pope Francis said Thursday, after the billionaire vowed to build a border wall to keep out immigrants. "Anyone, whoever he is, who only wants to build walls and not bridges is not a Christian," the pontiff told journalists during his return journey from a trip to Mexico in response to a question about Trump's anti-immigrant stance.
