In the normal course, an investigation is done in secret. The reason for that is to avoid attaching taint to an innocent person. But, in this case, the reason for conducting the investigation in secret facilitates dragging the Trump campaign through the mud. The longer the secrecy, the greater the damage.
Find a way to force the investigation itself into the open. Show the work. Let the public follow along as you subpoena information. Interview the witnesses in public, and so on.
As far as I know, appointing an SC absent a clear allegation of crime, is unprecedented. With Plame, the allegation was illegal leak of NOC identity. With Clinton, it was shady deals in Whitewater land development. With Daforth and the Waco massacre, there was the massacre.
In the appointment on Mueller, there is no allegation that the Trump campaign did anything illegal. NONE. Adam Schiff's fever imagination is not evidence.
Letting this investigation play out "in secret" is giving Adam Schiff and his fellow travelers the stage.
Keep repeating this until the cows come home. No alleged crime. No allegation. Nothing. Nada. . And somehow, a Special Prosecutor is named. Insane. Shut it down!
It's as if I get a knock on my door and they say, "Are you Art in Idaho?" "Yes." "I'm here to inform you a Special Prosecutor has been appointed by the Attorney General of the United States to investigate you."
"What for?"
"Well, you see, there really aren't any charges, no allegation you did anything illegal, no crime per se, but we thought you should be investigated." . .
