They also said their records are poor in general. "We don't have a record of X" thus does NOT rule out X having existed in the past.
State Department IT staff are on the record having told her multiple times that her method of communicating was preventing them from archiving her official email as required. Are you saying that despite the steps she took to make sure that no mail sent to and from her counterparts all around the world, to and from other agencies and branches of government (including the White House) , and to and from the well known mile-long list of donors to her family enterprise and political operation, that somehow there was a magic link between her private server and some archiving mechanism at State? A link that you think might exist, but which SHE acknowledges did not exist, and which some how - despite no email address involving state.gov being used in such communication - magically somehow got archived at State, and not one single example of such can be found by multiple investigative teams? And why would they find it - preventing it from getting into that system is exactly why she built a path around it. State's archives have copious correspondence from hundreds and hundreds of their other officials, staff, contractors, previous cabinet appointees and related users - just not a single scrap from her? Of course they don't: she didn't use that system.
And SHE HERSELF says that she thinks having corresponded with staffers inside State was a good enough way to retain those messages. She hand-picked reporters and pre-approved questions in the only Q&A she's allowed on the subject, and so conveniently was able to avoid being asked how she thought that method would apply when corresponding with people like Blumenthal (who hasn't denied that the leaked emails were his, by the way). Which is why she's never had to address the fact she wasn't personally taking any steps to CC or otherwise mirror all of the mail sent to and from her private server, as required by law. She hasn't mentioned CCing her State.gov mailbox that because at her direction, State's IT never even established an email account for her to which she would mirror her mail.
When finally capitulating to demands that her public records actually be made available, she didn't print out 55,000 pages of them because of a failure by the staff and systems at State, she printed them out because that was the only way she was willing to make them available. She could have forwarded them electronically, in their entirety, as required (so that, as the law requires, a government archivist can evaluate the messages and cull the official from the private). But no - she and her lawyers opted for a method that would absolutely maximize the additional delays in allowing other people to look through the records, would remove helpful header information, and would add untold thousands of hours of taxpayer-funded work to turn the documents back into searchable form. That was a deliberate choice that added work on her part in order to make the process more difficult and slow for investigators and the press, who had been requesting the documents for years.
I can only find Republicans claiming that, not objective (non-political) examiners.
Do you consider the investigation run congress when it was controlled by HER own party (which established after spending millions of dollars looking into related things, that there were NO such records at State) to have also been polticized against her? Now - under pressure - she's dumped hardcopies of the records that actually did exist all along (well, just some of them), and investigators who - unlike the last ones - aren't in her pocket for political gain say that the records have large date gaps. Unlike HER, they are conducting activity that will be entirely in the public record. When the investigators looking into this say something, you and they know that they will be fact checked to death by her political operatives. Despite her deliberate attempts to hide her communications from standard public review, you are giving her the benefit of the doubt ... but when a long-time career prosecutor (with a sterling record) and now congressman who knows that everything he says will be subject to endless review tells you what's present (and absent) in what are now public records available soon for YOU to look at, too, you're assuming he's lying?
What's that have to do with points being discussed?
It goes to establishing her deliberate actions in this area. In cases of private communications being mixed in with official ones, government archivists are supposed to look at ALL records, separate the official from the private, and return the private records to the person who blended them together. She knew this, and took actions to deliberately prevent such review. And knowing that subpoenas were coming, destroyed all evidence of how such decisions were made.
