No apologies.

Donald Trump took to Twitter Saturday morning to strike back at everyone criticizing him for not correcting a man who said President Barack Obama is a foreign-born Muslim. 

“Am I morally obligated to defend the president every time somebody says something bad or controversial about him? I don’t think so!” Trump wrote.

The Republican presidential candidate, who routinely attracts press with his biting put-downs, said this is the first time he caused controversy for not saying something.

Trump added that there is no way Obama would have corrected a misguided statement about him had the tables been reversed.

“If someone made a nasty or controversial statement about me to the president, do you really think he would come to my rescue? No chance!” he said.

The incident that kicked off the latest media frenzy occurred at the beginning of the brash billionaire’s town hall event Thursday in Rochester, N.H.

For the event’s first question, Trump called on an audience member wearing a Trump T-shirt who thinks the U.S. needs to “get rid” of Muslims.

“We have a problem in this country. It’s called Muslims. We know our current president is one. We know he’s not even an American. Birth certificate, man!” the man said, alluding to the “birther” movement. “We have training camps growing where they want to kill us. That’s my question: When can we get rid of them?”

While the unidentified man was speaking, Trump chuckled to other supporters, asking, “We need this question?”

In response, he said that he will “look into that.”

Many people, including Democratic presidential candidate Hillary Clinton, were offended that Trump did not explain to the man that Obama is in fact a Christian from Hawaii rather than a Muslim from outside the country.

“Donald Trump not denouncing false statements about POTUS & hateful rhetoric about Muslims is disturbing, & just plain wrong. Cut it out,” she wrote. 

White House Press Secretary Josh Earnest asked Friday morning if anyone was truly caught off-guard that this sort of behavior reared its head at a Trump event.

“Is anybody really surprised this happened at a Donald Trump rally?” Earnest said. “I don’t think anybody who has been paying attention to Republican politics are really surprised.”
