One of the NSA’s responsibilities is to make sure government agencies like the State Department have safe areas where sensitive and classified information can be discussed and stored. These are called Sensitive Compartmented Information Facilities, or SCIFs.

When a meeting is held inside one of these SCIFs, spies can’t snoop. And BlackBerrys don’t work inside a SCIF.

Hillary, my source says, requested that a non-secure room be built near the State Department’s Washington SCIF so that she could use her BlackBerry.

The request was approved — but against NSA protests. And that started a feud between Hillary and the NSA that only got worse with the Benghazi attack that killed Ambassador Christopher Stevens and a “foreign service information manager” — likely an NSA employee.

What is in Hillary’s e-mails is anyone’s guess — except, of course, for the Russians and the NSA employees who have seen them. But they probably include some very personal, embarrassing stuff as well as talks about Clinton Foundation donations.
