Potentially more disturbing is Strzok’s possible role in what many see as an even bigger scandal: the weaponizing of US intelligence against political opponents. Did he also sign documents asking a federal court to allow the FBI to spy on Trump advisers? It’s a critical question, because a so-called FISA document authorizing agents to monitor the communications of Trump adviser Carter Page, for one, reportedly was based at least in part on anti-Trump Russia propaganda promulgated in a dossier underwritten by the Clinton campaign — a partisan smear sheet that the FBI and Mueller have nonetheless used as a road map in their Russia probe.

In a Post interview, Page said he suspects Strzok, as the FBI’s No. 2 counterintelligence official, was also involved in applying for and obtaining the secret surveillance warrant on Page from the FISA court in September 2016. He adds that it’s “really interesting” that the dirty dossier found its way into Strzok’s orbit around the same time.
