A man with a white banner reading "ISIS here" appeared live on CNN in Ferguson, Missouri, behind anchor Jake Tapper late Monday night.
The Blaze initially reported the banner. Some U.S. commentators have tried to discredit the Ferguson protestors as violent looters, though the large majority of demonstrators have been unarmed and peaceful.
BuzzFeed reached out to CNN for comment. "No, I don't have any comment about a homemade banner a person holds up in a live shot behind our anchor while we are doing an interview during a protest," Bridget Leininger of CNN wrote in an email.
