An “alt-right”-affiliated outlet and fake news purveyors are pushing a highly dubious conspiracy theory from a fringe blog that acting FBI Director Andrew McCabe is a “ringleader” in a plot against President Donald Trump.

Big League Politics, a fringe blog founded by former Daily Caller writer Patrick Howley, cited an “inside source” to claim that McCabe was the “ringleader” behind a collaboration “against” Trump by McCabe, former FBI Director James Comey, and Russia probe special counsel Robert Mueller. According to Howley, the source also called the three men “creatures of the swamp.” The blog also employs “alt-right” figure Cassandra Fairbanks, and it previously helped revive a fringe smear that Comey was biased in his investigation into former Secretary of State Hillary Clinton’s email server due to his brother’s supposed connections to the Clintons. The McCabe article has drawn slightly more than 100 Facebook engagements so far, according to social media analytics website BuzzSumo.

Soon after it was published, the report was picked up by “alt-right”-affiliated blog The Gateway Pundit, which wrote that the revelations showed that Mueller is “in bed” with McCabe and Comey, that the three are working to “undermine” Trump, and that McCabe is the “real treat” of this “swamp fiasco.” Though The Gateway Pundit regularly pushes false stories, Fox News and Trump have regularly cited its content, the White House has given its correspondent press credentials, and the site is currently trying to get congressional press credentials. The Gateway Pundit’s McCabe article has received at least 6,200 Facebook engagements, according to BuzzSumo.

Thanks to the Gateway Pundit article, fake news purveyors then spread this dubious claim. Before It’s News wrote that the report meant “FBI directors past and present apparently have it in for” Trump, and The Political Insider said that it showed “the deep state is preparing for war.” Mad World News and Washington Feed wrote that McCabe was “execut[ing]” Comey’s “treacherous” “backup plan” and that Trump needs to “get rid of” these “deep state hacks.” Freedom Daily called the report a “bombshell” that showed a “treasonous plot” that “shady” McCabe was “execut[ing]," and that Trump needed to “act quickly” to “get rid of” him. The Political Insider, Mad World News, and Freedom Daily articles have received at least 2,000, 1,600, and 5,500 Facebook engagements, respectively, according to BuzzSumo.

The “alt-right”/fake news ecosystem pushing this dubious new charge has essentially been a propaganda machine for Trump, and the network continues to target Comey and Mueller as they become potential threats to the president. Mueller is leading the investigation into possible collusion between Russia and the Trump campaign in the 2016 election, and Comey has testified that he believes Trump fired him due to the probe. The new claim also comes as Trump tweeted that he is “being investigated for firing the FBI Director by the man who told me to fire the FBI Director” and that he is the target of a “witch hunt.”
