Normally the folks who have seen the underbelly of intelligence keep their mouths shut. Instead, this asshat goes and gets a job with a network.
As soon as these folks are employed in that fashion, security gets yanked. I can see a period of time during the first year where their might be a need to consult with key individuals of a prior admin.....but those days are long over.
Remember, as President, Trump knows everything. Two, he is great at reading people which gives him such an advantage over the rest of us mere mortals. Three, Brennen is a globalist socialist......the so called elite who think the rest of society is too stupid to know what is best.
I read this as another major move on the chessboard of draining the swamp.
The White House publishes a list of who's who in the realm of having their clearances checked and John Brennan is #1 in getting his publicly cancelled.
Said another way ' "You think Comey, McCabe et al. had problems you should really look at John Brennan; putting the spotlight back on him.
On a second theme, mentioning active employee Bruce Ohr also hints at a lot of fireworks coming. Putting Ohr's name out now is confirming a tie between Brennan and the not so Special Counsel and that so called investigation.
