NEWBERRY, S.C. (Reuters) - Pope Francis forcefully injected himself into the U.S. presidential campaign on Thursday, assailing Republican candidate Donald Trump's views on U.S. immigration as "not Christian" in a sign of growing international concern at the billionaire businessman's election prospects.
Trump struck back. No stranger to controversy, the longtime party front-runner in national opinion polls dismissed the leader of the world's Roman Catholics as "disgraceful" for questioning his faith. He said he was a proud Christian.
