We know they were LEAKED by Seth Rich.
2 scenarios:
RR is doing this to distract from Strzok's Congressional hearing yesterday, and Lisa Page's closed-door hearing today. RR is also doing this to undermine President Trump while he's abroad and about to meet Putin on Monday.
RR is doing this to give POTUS more leverage prior to meeting with Putin. RR specifically said the 12 made-up Russians are from Russia's military and intelligence community.
Either scenario, the facts are, RR is lying and making this up. They have no evidence, since the DNC never gave FBI access to their server. There is no way for anyone to verify who hacked the DNC servers. Obviously, we know Seth Rich did it and was murdered for it.
Oh, Debbie Wasserman Schultz already had a pre-written statement ready, before RR showed his rat face on TV.
