Not sure he flew anywhere.. Here is the gist of the article:
But the real question here is, when did the FBI/CIA/NSA learn about this dirt on Hillary? Well, if the meeting occurred on April 26, 2016, Brennan said he discussed the dirt on Hillary Clinton with Jim Comey and Mike Rogers:
BRENNAN: Well, first, I knew that it was a very intense Russian effort to interfere in the election, number one. Number two, I am well aware and have a lot of experience in observing what the Russians will do to try to suborn American citizens, to get American citizens to work for them. And this was a very intensive effort. And, so, as I said in my op-ed, myself and Jim Comey and Mike Rogers at the NSA, we talked about the importance of making sure that our radar, our collection radar was up so that we had early indications or be able to uncover any effort on the part of the Russians to work with American citizens.
The American citizens were reaching out to the Russians, as well, to see what they could get, see if they could [get] any dirt on Hillary Clinton. So, my radar was going because I knew the Russians were engaged in this effort and I was aware of contacts with American citizens that may have been totally innocent on the American citizens part and maybe they werent abetting at all.
So its safe to assume that the FBI/CIA/NSA learned about the dirt on Hillary Clinton somewhere in between April 26, 2016 (date of the Mifsud-Papadopolous meeting where the term allegedly originated) and August 5, 2016 when the FBI/CIA/NSA started reporting on the issue.
But Brennan recently gave an interview to Rachell Maddow where he said he didnt know the Russians were looking for Clintons emails until after he left office:
BRENNAN: So many things I learned since I left office because of what has appeared in the press. You know, the Trump Tower meeting with Don Jr. and others. And also when I was CIA director, I didnt know that it was the day that Mr. Trump basically gave a public call to the Russians to find Hillary Clintons e-mails, that it was in fact the same day that the GRU was actively looking for it (it being the emails) [source].
Brennan is not telling the truth again. For him to suggest that he didnt know about the Trump Tower setup with Donald Trump, Jr. or to suggest that the he didnt know of the events involving Papadopoulos and Misfud until after he was out of office are preposterous.
Brennan is full of canal water....
From the ICA of jan 6 2017
” The General Staff Main Intelligence Directorate
(GRU) probably began cyber operations aimed
at the US election by March 2016. We assess
that the GRU operations resulted in the
compromise of the personal e-mail accounts of
Democratic Party officials and political figures.
By May, the GRU had exfiltrated large volumes
of data from the DNC. “
