Pope questions Trump's Christianity

In response to the Pope's criticism of Donald Trump's plan to wall off Mexico, the Republican front runner called the remarks 'disgraceful'. Mr Trump said if and when the Vatican was attacked by the group Islamic State, the Pope would wish and pray that Donald Trump was president. The Republican businessman has called for a wall to be built along the US-Mexico border. Carol Swain, Professor of Political Science at Vanderbilt University in Nashville, told us how she thinks the spat will affect the campaign.
