"I have no doubt that there are Russian efforts to disturb the fabric of American democracy, but they're disruption efforts. The working theory behind the intelligence report on Russian interference in the president election is that Russia influenced American public opinion. We may not like that, but if it influenced American public opinion, at least in the guise of legitimate activity - which is what the report says - then there's nothing you can do about that. Where it would be improper and illegal would be if there was actual collusion in those efforts. We don't know that."
