“the report by Michael Horowitz found 17 “serious performance failures” relating to warrants obtained by the FBI through the Foreign Intelligence Surveillance Amendment (FISA) courts for the purposes of monitoring Page. The FISA warrant, which was reauthorized three times, contained false and misleading information about Page. It omitted that he had previously disclosed his Russian contacts to a government agency; it overstated the government’s confidence in the Christopher Steele dossier and ignored Steele’s own doubts about one of his sources; it declined to mention that Page had said he and Paul Manafort had “literally never met”; and in general it ignored information that rendered unlikely the theory that Page was a Russian asset.
These are alarming failures. They undercut the government’s position that FISA courts are a sufficient guardian of Americans’ civil liberties, and that the FBI is capable of responsibly exercising the vast powers granted to it. No one should feel confident that a court would block the FBI from engaging in surveillance, even if the information was flawed or faulty.”
