I think many of you are missing the biggest point. If there was no GOP involvement, everything points to the FBI creating this dossier and “laundering” it through John McCain to legitimize it.
The FBI created a fictitious document in order to acquire a “legal” FISA warrant in order to wiretap a presidential candidate and provide that info to the other candidate.
In any sane universe, that would mean decades of jail time for many senior FBI officials.
John McCain laundered it no matter where it originated.
“After the election, the FBI agreed to pay Steele to continue gathering intelligence about Trump and Russia, but the bureau pulled out of the arrangement after Steele was publicly identified in news reports.”
