The State Department has told Senate investigators it cannot find backup copies of emails sent by Bryan Pagliano, the top Hillary Clinton IT staffer who maintained her email server but has asserted his Fifth Amendment right and refused to answer questions on the matter.

And

State officials told the Senate Judiciary Committee in a recent closed-door meeting that they could not locate what’s known as a “.pst file” for Pagliano’s work during Clinton’s tenure, which would have included copies of the tech expert’s emails[.]

That’s interesting for another reason. A PST file is what Microsoft’s Outlook emailer uses to aggregate and store sent and received emails that are handled by Outlook; it’s not any sort of industry standard. Thunderbird, which I use, uses EML or MSF or…, depending on the vintage Thunderbird being used. Other emailers use other storage means. Why is State carefully looking only for PST files? Outlook is the State-mandated emailer, but State knows full well that other emailers also are used by State personnel and “consultants.”

The second supports my suspicion of the first: how hard is State looking, really?
