The only problem with that chronology is that McCain gave the dossier to Comey in December 2016 and the alleged FISA warrant was issued in October 2016. Some doubts are now arising that there was ever a FISA warrant.
And who is the source of that timeline? The FBI? The Justice Dept?
FISA warrants have certainly been a topic of conversation for months. I thought it was known that a FISA warrant was rejected in June or July of 2016, then granted in October?
