ROCHESTER, N.H. — Republican presidential front-runner Donald Trump has declined to correct a questioner at a town hall event who incorrectly stated that President Barack Obama is Muslim and said he’d be “looking at” claims of militant training camps on American soil.

Trump, who has a history of making controversial remarks about immigrants and other groups, was kicking off a town hall event Thursday evening in Rochester, New Hampshire — his first since Wednesday’s second Republican primary debate.

“We have a problem in this country. It’s called Muslims,” said the first man Trump called on to ask a question. “We know our current president is one. You know he’s not even an American.”

Trump, who was a driver of the “birther” movement that claimed Obama wasn’t born in the U.S, first responded with feigned exasperation — “We need the question,” he said, to laughs — but let the man continue.

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