David Rutz reports at FoxNews.com:

Hillary Clinton communications director Jennifer Palmieri struggled Sunday to defend her boss' claim that videos of Donald Trump's anti-Muslim rhetoric were being used as recruitment tools for the Islamic State.

Appearing on ABC’s This Week with George Stephanopoulos, Palmieri appeared uncomfortable backing Clinton's claim at Saturday's debate that fact-checkers from the New York Post and PolitiFact have debunked.  

"Um, the uh, uh, you know, Donald Trump, I think, was talking–uh, you know, what Secretary Clinton was saying last night is that one of the many dangerous things about Donald Trump is that, uh, his hot rhetoric, saying we shouldn't allow Muslim refugees into the country, is being used, and this is something that [an international group] has, who monitors social media and uh, on ISIS, has said --" the Clinton staffer is quoted as saying "before Stephanopoulos cut in," according to Fox News.

"But there have been no videos," Fox quotes Stephanopoulos as saying.

"Well, what they have said is that they are using him -- he is being used in social media by ISIS as propaganda," Palmieri reportedly said "sounding almost out of breath." Fox reports.

Hillary Clitnon "didn’t have a particular video in mind, but he's being used in social media, and uh, you know, what they haven't found is the video Mr. Trump keeps talking about, this alleged mystery video of thousands of people in Jersey cheering the collapse of the World Trade Center. But it is true he is being used in social media by, um, ISIS, to, to help recruit and propaganda," Palmieri said, according to Fox.

“But to be clear, you don’t have a video, as she said," Stephanopoulos stated, Fox reports (emphasis added).

Meanwhile, "She's" -- that is, Hillary Clinton's -- "a liar and everybody knows that," Donald Trump said Sunday on Meet the Press, in response to Clinton's accusation made during Saturday evening's Democrat debate, Newsmax reports.
