They never will go to court. Mueller knows Russia will never turn over 12 of their agents to us, any more than we would turn over 12 CIA agents based on a Russian indictment. So Mueller can avoid ever releasing anything he has to Congress or the public because it’s part of an “ongoing case”. He will never have to issue a statement that exonerates Trump. Meanwhile Trump’s foes can (they already are) point to the indictments as “proof” that it’s not a witch hunt.
I think it’s interesting that they are pushing the first case, what is it Concorde, and meeting resistance from Mueller
