An internal Fox News research briefing book obtained by The Daily Beast openly questions Fox News contributor John Solomon’s credibility, accusing him of playing an “indispensable role” in a Ukrainian “disinformation campaign.”

The document also accuses frequent Fox News guest Rudy Giuliani of amplifying disinformation, as part of an effort to oust former U.S. Ambassador to Ukraine Marie Yovanovitch, and blasts Fox News guests Victoria Toensing and Joe diGenova—both ardent Trump boosters—for “spreading disinformation.”

The 162-page dossier, entitled “Ukraine, Disinformation, & the Trump Administration,” was created by Fox News senior political affairs specialist Bryan S. Murphy, who produces research from what is known as the network’s Brain Room—a newsroom division of researchers who provide information, data, and topic guides for the network’s programming…

“The research division of FOX News produces a briefing book for all major stories, which serves as a standing collection of extensive data on major topics for internal use by all those in editorial functions. The Ukraine briefing book is nothing more than a comprehensive chronological account of what every person involved in the Ukraine controversy was doing at any identifiable point in time, including tracking media appearances of major players who appeared on FOX News and in many other outlets,” Mitch Kweit, senior vice president of the Brain Room, said in a statement to The Daily Beast. “The 200 page document has thousands of data points and the vast majority have no relation to FOX News—instead it’s now being taken out of context and politicized to damage the network.”
