Even if we accept Russian responsibility for the hack how do you know their motive is to sabotage the election? It seems to me that insider knowledge of the party is valuable on its own. Why do you think they are trying to influence the election?

It is likely that Hillary Clinton will be the next president of the United States. Would it not be valuable for Russia to have knowledge of her party? Do you think the CIA would be interested to have inside knowledge of United Russia?
