The Washington Post revealed Tuesday that the Hillary Clinton campaign and Democratic National Committee jointly paid for that infamous “dossier” full of Russian disinformation against Donald Trump. They filtered the payments through a U.S. law firm (Perkins Coie), which hired the opposition-research hit men at Fusion GPS. Fusion in turn tapped a former British spook, Christopher Steele, to compile the allegations, which are based largely on anonymous, Kremlin-connected sources. Strip out the middlemen, and it appears that Democrats paid for Russians to compile wild allegations about a U.S. presidential candidate. Did someone say “collusion”? This news is all the more explosive because the DNC and Clinton campaign hid their role, even amid the media furor after BuzzFeed published the Steele dossier in January. Reporters are now saying that Clinton campaign officials lied to them about their role in the dossier. Current DNC Chair Tom Perez and former Chair Debbie Wasserman-Schultz deny knowing about the dossier arrangement, but someone must have known. Perhaps this explains why Congressional Democrats have been keen to protect Fusion from answering dossier questions—disrupting hearings, protesting subpoenas and deriding Republican investigators.
The Fusion news means the FBI’s role in Russia’s election interference must now be investigated—even as the FBI and Justice insist that Mr. Mueller’s probe prevents them from cooperating with Congressional investigators. Mr. Mueller is a former FBI director, and for years he worked closely with Mr. Comey. It is no slur against Mr. Mueller’s integrity to say that he lacks the critical distance to conduct a credible probe of the bureau he ran for a dozen years. He could best serve the country by resigning to prevent further political turmoil over that conflict of interest.
