I hope what you say is going to happen. It doesn’t matter whether he has already been indicted. It only matters if he has been given immunity or has already cut a deal on the US charges. That could easily happen or have already happened. IMHO I think it is more likely that the DOJ is just using this as a false flag event and nothing ever happens. Guccifer may want to testify but if the DOJ does not call him before the court then he will not get to speak at all. 18 months is too long to wait for the damage. The DOJ could have easily struck a deal with him while he was in Europe but that doesn’t appear to be the case. Obama runs the DOJ thru Lynch.
It does matter that he’s been indicted. Evidence has been presented to a federal grand jury to get the true bill (indictment).
