The phrase “CNN is ISIS” started trending on Twitter Saturday afternoon as Trump supporters had fun heckling the network.

Pro-Trump conspiracy theory website InfoWars got the trend started by offering $1,000 to “anyone who is seen on TV with a ‘CNN is ISIS’ t-shirt or sign,” apparently in reference to comedienne Kathy Griffin’s ISIS-like photo shoot pretending to behead President Trump. CNN fired Griffin from her role as the co-host of the network’s annual New Year’s Eve program in response to the controversial photo.

At a rally in Washington, D.C., a Trump supporter was seen standing in front of CNN cameras holding a sign that read: “CNN Is ISIS.”

As CNN spent Saturday afternoon promoting anti-Trump protests taking place around the country, more images began popping up online of pranksters holding “CNN Is ISIS” signs.

And the heckling continued…
