This would suggest it's not Carter Page. Page's name has already been out on the table for some time, would not need to be "sniffed out."
Kim wonders when this FBI operation actually started, was it prior to the July 2016 Papadopoulos drinks night when the FBI claimed it started?
I would guess that John Brennan's meeting in Moscow on March 14 with the Russian FSB intel service had something to do with starting it.
By mid-March Jeb had pulled out and it looked like Trump would be it on the Republican side.
Brennan went to his counterparts in the Russian intel agency and probably asked what they had on Trump.
Either one of two things may have happened: Ivan had little to offer so Brennan hatched the idea of fabricating Russian dirt and injecting it into the FBI; or Ivan gave Brennan a dossier of disinformation while trying to conceal their snickers as they handed it to him, and Brennan then laundered it through Steele.
The sniffing relates less to the name and more to what he was doing. Theyve been portraying Carter as someone who joined Trumps staff and then embarrassed him or worse. This suggests that he was a CIA spy all along. So its a fraud on the justice system and on the American people.
“Either one of two things may have happened: Ivan had little to offer so Brennan hatched the idea of fabricating Russian dirt and injecting it into the FBI; or Ivan gave Brennan a dossier of disinformation while trying to conceal their snickers as they handed it to him, and Brennan then laundered it through Steele.” Best guess that I have seen.
