Just about the most plausible explanation I have seen.
Provable? Unlikely, as the WhiteyHut coverup will continue right up to Jan. 2017.
With the latest on FBI finding hitlery’s “private” emails intact, she will suspend her campaign for health reasons, shortly and will tell all the dems to go with Joe.
I suspect that this was all done entirely on purpose to give “donors” access to sensitive information while retaining some patina of plausible deniability.
