I'd bet that has more to do with her legal danger.
If her IT guy Cambetta talks, then whoever told him to alter her email database (Cheryl Mills?) is in serious legal danger.
I'm sure Hillary and her lawyers are spending hours right now on trying to keep Cambetta, her staff, the DOJ and the FBI all on board with the cover up.
Might take a personal assurance from Obama to pardon Cambetta, Mills and everyone to keep this pot from boiling over for Hillary.
It's really too late to stop this because no prosecutor or anyone for that matter is going to risk jail tie for interfering with a Presidential election, which carries with it .a stiff prison term Up to this point it's all been "talk" from the Oversight committee to the Dept's throughout our Governance. If they were really going to get her they would have done so by now. Imo....but nobody is willing to stick their own neck out to do that.
