The FBI, in its ham-handed FISA application on former Trump campaign adviser Carter Page, somehow forgot to include the fact that Russian spies thought Page was an "idiot" who was unworthy of recruiting, according to Paul Sperry of RealClear Investigations.
The FBI was aware of Russians’ skepticism that Page knew anything of value or was a significant player because the bureau had recorded them voicing such doubts in a wiretap, from an earlier espionage case involving three Russian spies working undercover for the Kremlin in New York. -RCI
The FBI of course used that 2013 case as part of the FISA application - claiming to have evidence of Page's recruitment by the Kremlin, however the "idiot" part was deliberately withheld.
They have been made public only in redacted form, professing evidence that Page was “recruited" by Russian intelligence and had "coordinated" with the Russian government. But “that’s a mischaracterization of the facts in the case,” a congressional source said. -RCI
