Donald Trump is under fire for failing to correct a supporter who called President Obama a Muslim.
An unidentified man at Trump's New Hampshire rally on Thursday evening said: "We have a problem in this country. It's called Muslims. We know our current president is one. He's not even an American."
Trump then said: "We need this question. This is the first question."
Trump didn't correct the questioner, who went on to attack Muslims.
The supporter asked: "We have training camps growing where they want to kill us. That's my question. When can we get rid of them?"
Trump replied: "We are going to be looking at a lot of different things. A lot of people are saying bad things are happening out there. We are going to be looking at that and a lot of different things."
Trump famously demanded Obama release his birth certificate in 2011 when he was considering running for president.
Hillary Clinton was campaigning nearby and tweeted:
Donald Trump not denouncing false statements about POTUS & hateful rhetoric about Muslims is disturbing, & just plain wrong. Cut it out. -H- Hillary Clinton (@HillaryClinton) September 18, 2015
Trump's response is being contrasted with how John McCain handled a similar incident on the campaign trail in 2008.
A woman supporting McCain at the time told the GOP candidate that Obama was "an Arab."
McCain fired back and said: "No ma'am, he's a decent family man and citizen. I just happen to have disagreements with him."
CNN's Anderson Cooper went head-to-head with Trump supporter Andy Dean, who is also the former president of Trump Productions, over the New Hampshire incident on live TV.
Dean said: "You may laugh it off but there are reports of Middle East radicals in training camps."
Cooper replied: "Andy, I've spent more time in the Middle East than you have in your little life! So don't tell me about laughing this stuff off!"
Minutes later, Cooper apologized: "Andy, I was rude to you. I shouldn't have been."
"I'm used to it, don't worry. I have an older brother," Dean said.
Trump's rally was packed with supporters - which came in sharp contrast to a sparse attendance for Jeb Bush in Las Vegas.
