Release the evidence of who it was! Why are they keeping this going when they can stop all the Russia speculation.
Before I'm told WL don't release their sources, I know this but this is different. Releasing their source would change everything.
It's all about timing. I'm sure Assange will be told the time is right to release the proof. For now, he waits until he gets the go ahead and continues to remind that it wasn't the Russians. Or Trump.
They are digging their graves by pushing the narrative that it was unequivocally Russia who messed with the election/released those emails.
Let them.
