Watters Gets New Yorkers' Thoughts on ISIS...

Donald Trump called Hillary Clinton a liar this morning on "Fox and Friends" for claiming that his rhetoric is helping ISIS to recruit. 

Trump said Clinton's claim that he appeared in an ISIS propaganda video turned out to be false.

"She lies so much. Whether it's her trips where she's going to be shot down and it turns out that didn't happen and, ya know, Whitewater was a total lie. There are so many lies. It's terrible," said Trump.

Trump again called on Clinton apologize, but acknowledged that she probably will not.

"I actually think it would be good for her if she would apologize," said Trump.

Clinton alleged during the Democratic debate on Saturday that Trump is becoming "ISIS' best recruiter."

"They are going to people, showing videos of Donald Trump insulting Islam and Muslims, in order to recruit more radical jihadists," she said.

Trump, who joined the show on Elisabeth's first day as "Fox and Friends co-host, also wished her well on her last day.

"We've had a great run. We've had a lot of fun together with these two guys next to you," said Trump.
