Here are a few of the details from the New York Post report:
The FBI is investigating whether members of Hillary Clinton’s inner circle “cut and pasted” material from the government’s classified network so that it could be sent to her private e-mail address, former State Department security officials say.
The two systems — the Secret Internet Protocol Router Network (SIPRNet) and Joint Worldwide Intelligence Communications System (JWICS) — are not connected to the unclassified system, known as the Non-Classified Internet Protocol Router Network (NIPRNet). You cannot e-mail from one system to the other, though you can use NIPRNet to send e-mails outside the government.
Somehow, highly classified information from SIPRNet, as well as even the super-secure JWICS, jumped from those closed systems to the open system and turned up in at least 1,340 of Clinton’s home e-mails — including several the CIA earlier this month flagged as containing ultra-secret Sensitive Compartmented Information and Special Access Programs, a subset of SCI.

So they’re investigating whether members of the Clinton team “cut and pasted” material from a top-secret server. Just great.

Yet another piece to the puzzle that is this massive scandal. As for Clinton’s explanation? It will probably go something like this…
