Donald Trump is facing criticism after a town hall in New Hampshire when during a Q&A one of his supporters stood up and said President Obama is a Muslim and not even an American, and asked when the United States could get rid of Muslims.

Donald Trump: “OK, this man. I like this guy.”

Man: I’m from White Plains. Amen, OK? We have a problem in this country. It’s called Muslims. We know our current president is one.”

Donald Trump: “Right.”

Man: “You know he’s not even an American. Birth certificate, man.”

Donald Trump: “We need this question; this is the first question.”

Man: “But anyway, we have training camps brewing where they want to kill us.”

Donald Trump: “Mm-hmm.”

Man: “That’s my question: When can we get rid of them?”

Donald Trump: “We’re going to be looking at a lot of different things. And, you know, a lot of people are saying that, and a lot of people are saying that bad things are happening out there. We’re going to be looking at that and plenty of other things.”

After the event, Hillary Clinton tweeted, “Donald Trump not denouncing false statements about POTUS & hateful rhetoric about Muslims is disturbing, & just plain wrong. Cut it out.” Later, Trump’s campaign issued a statement to The Washington Post saying, “The media wants to make this issue about Obama. The bigger issue is that Obama is waging a war against Christians.”
