I'm sure they are. Fortunately we can trust senior members of the DoJ such as Comey, Sessions, Mueller... Oh, wait, no we can't. Face it - that information is being scrubbed just as fast and as hard as the yet undetected corrupt can scrub it.
It's time for an independent counsel and non-DoJ staff who are NOT Clinton donors to take custody of the raw data if it isn't already too late. The DoJ cannot be trusted to investigate itself. That's what got them, and us, into this mess. The corruption is too deep and the pattern of evidence suppression, laundering, and outright destruction is far too well-established for any trust in this matter.
The Swamp will be completely drained in about two weeks.
