So has Carnac the Magnificent told us what these unopened emails say yet...
Well, they illary servers were scrubbed before the FBI could look at them, but it's very possible that she sent emails to / from huma and huma was using her hubby's laptop. That laptop was not scrubbed, so all of a sudden there might be some interesting emails there that had been scrubbed from the server. Or, there might be nothing new. Given that there was the letter, I'd say they found something interesting. Huma for sure has some 'splainin to do, because she supposedly claimed she had never used her husband's laptop, yet emails to / from her were apparently found on it.
