John Podesta says he has what he calls "circumstantial" evidence that top Trump advisor Roger Stone had advance word of the hacking his email. But he points to a late August tweet that does seem like Stone had advance word that Podesta was the next target of an attack. Remember, Stone has already said - true or not - that he is in communication with Julian Assange. Wikileaks is the go-to distribution hub for emails stolen by Russian security services. Why the tweet.
