U.S. Republican presidential candidate Trump speaks at a campaign town hall meeting in Rochester.

Republican presidential candidate Donald Trump drew fire from Democrats and some Republicans Friday after declining to correct a questioner at a town hall event who wrongly said President Barack Obama is Muslim.

“He knew, or he should have known, that what that man was asking was not only way out of bounds, it was untrue,” Hillary Rodham Clinton, the Democratic front-runner, said after a campaign event in New Hampshire. “He should have from the beginning repudiated that kind of rhetoric, that level of hatefulness.”

The question to Trump came Thursday night at a town hall in Rochester, New Hampshire. The first person the billionaire real estate mogul called on said, “We have a problem in this country. It’s called Muslims.”

“We know our current president is one,” the man continued. “You know he’s not even an American.”

Trump, a driver of the “birther” movement that falsely claimed Obama wasn’t born in the U.S., first responded with feigned exasperation – “We need the question,” he said, to laughs – before letting the man continue.

“We have training camps growing where they want to kill us. That’s my question,” the man in the audience continued. “When can we get rid of it?”

Trump did not dispute the man’s assertion that militants operate training camps on American soil and said he’d heard others raise the issue.

“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,” said Trump. “We’re going to be looking at that and plenty of other things.”

At the White House, press secretary Josh Earnest said Friday it was unfortunate that Trump “wasn’t able to summon the same kind of patriotism” that Republican Sen. John McCain showed in 2008, when he took the microphone away from a woman who said she didn’t trust Obama because he was Arab.

“Mr. Trump isn’t the first Republican politician to countenance these kind of views in order to win votes,” Earnest said. “That’s precisely what every Republican presidential candidate is doing when they decline to denounce Mr. Trump’s cynical strategy.”
