What OBVIOUSLY needs to be opened up is possible Putin-Billary, Inc. collusion via the Steele dossier.
A special prosecutor needs to use the DIA and it’s covert teams (not the FBI or CIA), to look into possible behind the scenes help and cooperation from and with Putin in putting the Russian side of the Steele dossier together for Billary, Inc.
Flynn led DIA ... Flynn set up the sting. Flynn got a spanking NDA. Trump knows all ;)
