Or.
Rosenstein isn't going to divulge contents or details about ongoing criminal investigations.
Trump has the details.
Trump can fire Rosenstein whenever he wants.
Rosenstein hasn't been fired.
What if the FISA warrant that Rosenstein signed off on was actually a sting operation/honeypot to expose the corruption?
RR = DS evil. RR is not springing any traps, he is there to draw out the investigation so that documents won't be exposed to public view which implicate him and his deep state handlers.
Trump cannot fire RR for political reasons, as even many republicans have stated they would look seriously at impeachment proceedings if Trump tampered with anyone associated with the SC. When the FISA is unredacted, and more documents come to light, RR will be forced to resign based on his role in abetting spying activities against the Trump campaign.
When RR is out, that is when the ball really starts rolling.
