I've been saying it for some time now. Q has been saying it for some time, as well.
Mueller and Rosenstein were the final interlock for the launch. The final hold on the mission. Everything else going on in the background was setup and staging.
President Trump is playing "king of the hill" and moving people in and out of positions who either think they are getting away with a con, or who are needed to ensure integrity of the judicial/legal process. This is why President Trump is able to pretend like he's not really doing anything. In many ways - he isn't. Simply him being there and not being corrupt or handled by the deep state allows the system to self-purge as it was supposed to, all along.
The big show does require some setup and staging, and that is what Mueller and Rosenstein were for. Once they are cleared, the mission is in final countdown to T=0 - which is the FISA declass. But that is only the start of the mission. The mission timer then begins to count up with events on it, afterward.
Anyway - another one that is going to blow some minds is Kushner.
Remember how the media went nuts about how Trump may have forced the issue regarding Kushner's security clearance? The snippet from the Press Secretary included an oddly specific comment regarding whether or not the issue of security clearances on the President's transition team (leaks) were leveraged/forced.
Just saying. Someone had to put Manafort into the campaign.
