From MoA:

Obama made it possible for the FBI to directly access everything NSA had on Trump, et al. Obama supercharged the FBI’s ability to investigate Trump…

The Obama administration enacted the executive order EO 12333 in early January 2017, shortly before Trump took over…

The hasty FBI move after Comey was fired activated this instrument. The Mueller investigation has since used it extensively…

Mike Flynn: pleaded out to a minor charge, rolled over in full and then produced five rounds of documents. Likely: Flynn was confronted with the intel they had on him and knew he was cooked. They knew the crimes. They heard and saw everything. There’d be no escape.

By flipping and pleading out Flynn, all of that secret intel stays secret. Our intelligence efforts are protected. And Flynn goes down. And he cooks a bunch of other gooses. He’s savvy enough to know that once they have the intel, all that’s left to do is make the case.

“On Thursday November 17th, 2016, NSA Director Mike 
Rogers traveled to New York and met with President- 
Elect Donald Trump.

On Friday November 18th The Washington Post reported 
on a recommendation in “October” that [NSA Director 
Admiral Mike Rogers] Mike Rogers be removed from his 
NSA position:

The heads of the Pentagon and the nation’s 
intelligence community have recommended to President 
Obama that the director of the National Security 
Agency, Adm. Michael S. Rogers, be removed.

In a move apparently unprecedented for a military 
officer, Rogers, without notifying superiors, traveled 
to New York to meet with Trump on Thursday at Trump 
Tower.

Occam’s Razor. NSA Director Admiral Mike Rogers 
didn’t want to participate in the spying scheme [on 
Trump]

(Clapper, Brennan, Etc.), which was the baseline for 
President Obama’s post presidency efforts to undermine 
Donald Trump and keep Trump from digging into 
[who knows what crimes]”

After the visit by Rogers, Trump vacated Trump Towers.
