Why is that a bombshell? We knew it then, we know they still don’t have any evidence and never will have, we know that Russia wasn’t who hacked the DNC server and gave the emails to Wikileaks, that was Seth Rich and it wasn’t a hack, it was downloaded to a flash drive. The only people who don’t know those things are the ones who watch MSNBC and CNN all day breathlessly discussing the Manafort and Cohen pleas.
A bombshell will be when she testifies that there was a conspiracy to frame candidate and President Trump with a Russia collusion story that they knew was a hoax, or the release of documents showing that that is what they did.
It’s a bombshell because it suggests/proves that the law was broken by having NO basis to have a Special Prosecutor.
