“FBI monitors government emails.”
The FBI is not allowed to monitor CIA communications - they are considered private to that agency. Can’t have FBI guys running around with CIA information. Who let them do that? Holder isn’t high enough to authorize anything pertaining to the CIA. Think only the president could authorize that.
The CIA said yesterday only they do investigation of CIA applicants and employees - the FBI does not, is not allowed to.
What I've seen suggests it was an automated NSA email filter. The phrase "under the desk" flagged one of the emails for possible scrutiny as evidence of financial corruption. When a human analyst looked, it was obvious what was really going on. And, only at that point, probably after the WH was informed, was the FBI called in to investigate.
