Trump has come under fire for not correcting the questioner, who asserted that President Obama is not American.
"We have a problem in this country. It's called Muslims," the unidentified man prefaced his question. "You know our current president is one. You know he's not even an American."
Trump laughed off the statements and did not correct the false claim.
“We need this question? This is the first question?" Trump asked the audience.
That’s when things got really weird.
"Anyway,” the Trump supporter continued, “we have training camps growing where they want to kill us," he said.
"That's my question: When can we get rid of them?"
"We're going to be looking at a lot of different things. You know, a lot of people are saying that and a lot of people are saying that bad things are happening. We're going to be looking at that and many other things."
In 2008, John McCain corrected an audience member who made similar claims, referring to Obama as an Arab. The statement had garnered boos even from the conservative crowd.
Trump, on the other hand, has previously demanded to see the president’s birth certificate, which he claims is a forgery, adding fuel to the crazy fires.
Outrage over Trump’s comportment has been echoing throughout social media ever since, with the Republican frontrunner even being told to “cut it out,” by Hillary Clinton through a tweet.

Twitter favorite Bernie Sanders also demanded an apology.

"Trump must apologize to the president and American people for continuing the lie that the president is not an American and not a Christian," Sanders tweeted on Friday, gaining over 5,000 retweets by 2 p.m.
Trump, remarkably, has so far refused to comment on the incident to the media, and has even remained silent on his typically volatile Twitter account.
His campaign, however, released a statement saying that the room was noisy and that Trump had trouble hearing the question, despite the man speaking into a microphone. They also claimed that the president is waging a war on Christians.
"The media wants to make this issue about Obama. The bigger issue is that Obama is waging a war against Christians in this country," the statement reads. "Christians need support in this country. Their religious liberty is at stake."
