Again...this is a start but this is not the final piece to prove to the country impeachment is required.
Right. And people like you have been mocking and downplaying this investigation for months now. "Where is it? I don't see anything". Today your tone is "this is a start, but...".
I don't think Mueller has tried to jump the gun for a reason. He's been deliberate and progressively building a case. He's been very tightlipped as well as his team. Really the only thing I can remember leaking was Manafort being indicted. That news broke late Friday and it was done on Monday.
You're crazy if you think this is Mueller's hail mary to take down Trump. He's probably got a lot of evidence we don't know about. The next part is connecting all the dots and putting the pieces together. Flynn is not the biggest piece of the puzzle. He's simply an opened door Mueller can now use.
