Fox News knows that the president’s personal lawyer Rudy Giuliani is pushing lies about former Vice President Joe Biden’s actions in Ukraine in order to damage his political prospects, and the network is going to keep hosting him and Fox contributor John Solomon, another participant in the effort, until they get the job done.

The Daily Beast published a bombshell story Thursday revealing the existence of an internal briefing book compiled by Fox News’ “Brain Room” -- a newsroom division which compiles research for on-air talent based on credible sources like Media Matters -- warning of an “unrelenting disinformation campaign originating from Ukraine” which targeted Biden and involved several key Fox players.

Notably, the 162-page document described the “extensive role” Giuliani played in “spreading disinformation,” which originated with corrupt Ukrainian figures, and said that Solomon “played an indispensable role in the collection and domestic publication of elements of this disinformation campaign.” It also pointed to the impact of “domestic media outlets” -- including Fox -- “in amplifying the distribution of these storylines.” (From 2018 through last Thursday, Giuliani, Solomon, and fellow participants Joseph diGenova and Victoria Toensing collectively made at least 348 total appearances on weekday Fox News programs.)

That’s an incredibly damning report on the credibility of Giuliani and Solomon -- and that of any news outlet that promotes their allegations. It suggests that the president’s lawyer is either deliberately lying or is an unwitting pawn of Ukrainians who have their own interests in smearing Biden. It states outright Solomon’s modus operandi: “Focus on stories from disinformation campaign, non-disclosure of conflicts, use of unreliable sources, publishing false and misleading stories, misrepresentation of sources, and opaque coordination with involved parties.” And it makes clear that Fox is misinforming its viewers by putting both figures on the air to discuss their wild claims.

Fox’s actions since the document was written suggest that the network knows exactly what it’s doing: deliberately operating as a propaganda outlet aimed at misleading its viewers for the president’s political benefit. The pro-Trump outlet has not curtailed Giuliani’s appearances and has actually hosted him twice for softball interviews to push allegations about Ukraine and Biden since the briefing book’s existence was first reported last week. Fox Business also hosted Solomon to discuss a new Ukraine story after the document’s contents were revealed.
