According to the Associated Press:

Former Secretary Hillary Clinton failed to turn over a copy of a key message involving problems caused by her use of a private homebrew email server, the State Department confirmed Thursday. The disclosure makes it unclear what other work-related emails may have been deleted by the presumptive Democratic presidential nominee.

Ok, so already one message that was clearly work related was likely amongst the deleted 30,000+ "Personal" emails Clinton failed to turn over. This adds considerable doubt to her assertions that she surrendered ALL of the work related emails and will illustrate her lack of trustworthiness and integrity, Trump will use this to great effect in the general if she is awarded the nomination and isn't forced to retire from the race.

The email was included within messages exchanged Nov. 13, 2010, between Clinton and one of her closest aides, Deputy Chief of Staff Huma Abedin. At the time, emails sent from Clinton's BlackBerry device and routed through her private clintonemail.com server in the basement of her New York home were being blocked by the State Department's spam filter. A suggested remedy was for Clinton to obtain a state.gov email account.

"Let's get separate address or device but I don't want any risk of the personal being accessible," Clinton responded to Abedin.

Clinton never used a government account that was set up for her, instead continuing to rely on her private server until leaving office.

I guess if you are gonna try to destroy records you should make sure you get all other parties to do so as well, something her trusted aide failed to do, which is how it was discovered (This is not from the leaked files or recovered from Clinton's hard drive)

The email was not among the tens of thousands of emails Clinton turned over to the agency in response to public records lawsuits seeking copies of her official correspondence. Abedin, who also used a private account on Clinton's server, provided a copy from her own inbox after the State Department asked her to return any work-related emails. That copy of the email was publicly cited last month in a blistering audit by the State Department's inspector general that concluded Clinton and her team ignored clear internal guidance that her email setup violated federal standards and could have left sensitive material vulnerable to hackers.

"While this exchange was not part of the approximately 55,000 pages provided to the State Department by former Secretary Clinton, the exchange was included within the set of documents Ms. Abedin provided the department in response to our March 2015 request," State Department spokesman John Kirby told The Associated Press on Thursday.

The Sd's will be voting for Trump if they cast their ballot for Clinton at the convention.

There is just so much THERE there and every bit of it will be used against her successfully.

The people already don't trust her, this latest example proves they are right in not doing so. That doesn't sound like the makings of a "Strong Candidate" for the general.

If we end up with Trump and the Clintonistas try to lay a Trump Presidency on "Naderite's" and Bernie Bro's, etc it won't work this time. It will be because the DNC in it's arrogance thought it could be completely dismissive of a significant portion of it's base without repercussion...
