A Hillary Clinton spokesman says "hell, no," the candidate won't apologize to Donald Trump for calling him "ISIS' best recruiter."

"Hillary Clinton will not be apologizing to Donald Trump for correctly pointing out how his hateful rhetoric only helps ISIS recruit more terrorists," said spokesman Brian Fallon in a statement.

In Saturday night's Democratic debate, Clinton suggested that ISIS is "showing videos of Donald Trump insulting Islam and Muslims in order to recruit more radical jihadists."

Politifact rated the claim "false," saying that - while experts say that ISIS could be circulating Trump's sentiments to bolster their arguments that the West is at war with Islam - there's no evidence to date that his rhetoric has been used in recruiting videos.

On the TODAY Show on Monday, Trump said that he would demand an apology from Clinton for her remark.

"She lies about emails, she lies about Whitewater, she lies about everything. She will be a disaster about everything as president of the United States," he said.

Asked on Meet the Press on Sunday whether or not he would change his language if his words were being used in ISIS recruitment videos, Trump offered a firm no.

"No, because I think that my words represent toughness and strength. Hillary's not strong, Hillary's weak, frankly," he said.
