I would hope that Trump has a whole dossier by now on the malfeasance of Rosenstein and Mueller, etc. and he should start to leak it and tweet it.
He has lots on them ad this little action is being done by the DS to deflect the condemnation and scrutiny that will come when the IG report and other revelations hit the airwaves. Mueller&RR always follow a pattern that whenever damning information is out n about they do something like this. They are going to swing for what they have done.
