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.
The reaction on Twitter was largely not impressed.
!!!! NOT ok RT @dorseyshaw: That "ISIS here" banner in #Ferguson wasn't a photoshop. https://t.co/QGcoTfiyBC
Why didn't someone tear down the ISIS sign spotted in #Ferguson ? And chase away the terrorist who brought it to the protest?
If the Republic survived "Bongs Hits 4 Jesus," it'll survive this. RT @dorseyshaw: "ISIS here" banner in #Ferguson
