Huma obviously lied to the investigators that she turned over all devices that might be pertinent to the investigation. Even if these are all the “same old e-mails” she didn’t fully cooperate with the investigation, and she should be in grave legal jeopardy.
I’m not convinced that Comey would do this if HUMA were in jeopardy.
It would have to be info that had Clinton in jeopardy.
That will be the only justification.
