A brief history of Trump's feud with Pope Francis

Pope Francis exchanges gifts with US President Donald Trump (C) and US First Lady Melania Trump during a private audience at the Vatican on May 24, 2017. US President Donald Trump met Pope Francis at the Vatican today in a keenly-anticipated first face-to-face encounter between two world leaders who have clashed repeatedly on several issues.

Trump praised the pope at the start of Francis's papacy, in 2013. But relations soured during the 2016 election, when Francis criticized Trump's proposal to build a wall on the U.S.-Canada border.
