I believe the intended meaning was that the people on the OTHER end of Clinton's State Dept. emails would still have all the recoverable emails from the advisory process. The problem with that idea is that it wasn't the people inside State who were directly involved in the skulduggery, THEIR emails would all simply cover the things they were supposed to be doing in evaluating and advising on the decision in accordance with their duties...she would not have mentioned her ulterior motives to them in the emails, it was the people OUTSIDE State that she may have been emailing whose emails would actually prove what kind of crap she was really doing.
