Three years later and the results are in.
In a letter sent to Sen. Chuck Grassley (R-Iowa) earlier this week, which was released Friday, the State Department said it found "no pervasive evidence of systemic, deliberate mishandling of classified information" after wrapping up its internal investigation launched in 2016 related to former Secretary of State Hillary Clinton's use of private email during her tenure.
That appears to be mostly good news for Clinton and the Department, but the investigators did, however, determine that 38 unidentified current and former State Department officials were "culpable" in 91 cases of sending classified information that ended up in Clinton's personal email, meaning the use of private email did increase the vulnerability of such information.
Any of the 38 officials still working for the State Department could reportedly face some form of disciplinary action, while the violations will be noted in the files of all 38, and will be considered when applying for or renewing security clearances. All in all, the investigation covered 33,000 emails and found 588 violations, though it could not assign fault in 497 cases. Read more at The Associated Press and The Guardian.
