An internal report from the Fox News research department warns that several prominent Fox News guests, aided sometimes by omissions from Sean Hannity, have spread “disinformation” about Ukraine. The briefing, written by senior political affairs specialist Bryan S. Murphy and titled “Ukraine, Disinformation, and the Trump Administration,” was first disclosed in a series of tweets from former Fox News freelancer Marcus DiPaola, then obtained in full by The Daily Beast. Murphy compiles reports for the Fox News “Brain Room,” a research arm of the network’s news division.The report specifically points to “disinformation” on Ukraine from President Trump’s lawyer Rudy Giuliani, Fox News contributor and Hill columnist John Solomon, and married legal team Joe DiGenova and Victoria Toensing.DiGenova and Toensing are part of Trump’s legal circle and also represent Ukrainian oligarch Dmytro Firtash, a fact not disclosed last fall when they were “spreading disinformation” on Fox News and “parroting … beneficial narratives while employed by Firtash,” Murphy wrote. Giuliani had a “high susceptibility to disinformation” from Firtash and former Ukrainian prosecutor general Yuriy Lutsenko, he added, and Solomon, an opinion columnist typically referred to as an “investigative reporter” by Hannity, “played an indispensable role in the collection and domestic publication of elements of this disinformation campaign.” Trump cites Solomon’s work, now under review by The Hill, while defending himself in the Ukraine scandal.Mitch Kweit, senior vice president of the Brain Room, told The Daily Beast that “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.” Read more at The Daily Beast.More stories from theweek.com Elizabeth Warren’s last chance One of Trump’s first political appointees endorses Bloomberg for president The real State of the Union
