IIRC, Donald Trump never uses e-mail on the advice of his attorneys. If anymore e-mails are leaked they won’t be Trump’s.
The converse of the DNC leak would be a hack into the RNC, not Trump. I was saying that such a hack would not hurt Trump, it would show that he overcame the RNC obstruction. It might show how over the months Reince went from fighting him to becoming his bitch.
