Trump says he'd send back Syrians taken in by US

Republican presidential front-runner Donald Trump said Wednesday that if he's elected president he would send back Syrian refugees taken in by the US because they may be Islamic State militants in disguise.

The billionaire businessman, who is leading early opinion polls, said during an hour-long speech, which included several profanities, that he was worried the refugees, who have been fleeing their country after years of civil war, could be Islamic State militants looking to get into the US.

"I'm putting the people on notice that are coming here from Syria as part of this mass migration," Trump said during an evening rally in Keene, New Hampshire. "If I win, they're going back."
