This isn't new but is just starting to get some press. It's been hinted/leaked numerous times by top officials in the FBI.
The going "rumor mill"/leaked FBI assertions are that the DOJ/Lynch has been shutting down the FBI on several investigations including the Hillary Email Server investigation, handing out immunity like candy, supporting or looking the other way on collusion of Hillary for America and the Foundation. Many FBI sources have recently been saying Comey wanted the DOJ to prosecute Hillary but he was shot down and told to bury it or else...
Comey has stacks of FBI agent resignations because of these issues. Many think his re-opening of the FBI investigation of Hillary's Email Server is him fighting back with a f*ckit mentality and that he's now going to charge the FBI to go full bore to prosecute the Clinton's if there is proper evidence.
Seems to make sense based on everything starting to come out. I hope we don't see this going overboard, but justice needs to be done.
Nothing more or less, just normal justice.
