Last night at the premier of Hating Breitbart in Washington DC, FOX News contributor and Huffington Post writer Ryan Clayton was escorted from the theater. ... This was after he got up and started screaming in the middle of the film. ... Far left activist Ryan Clayton has appeared several times on FOX News. ... Ryan Clayton actually appears in the Hating Breitbart documentary where he talks about the need for civil discourse in society… And then is seen viciously attacking Andrew Breitbart. Unreal.
