The FBI is looking into several scenarios which may have resulted in what we now know was thousands of classified documents appearing on Hillary Clinton’s private e-mail server.

Of those scenarios, one conclusion seems apparent: Clinton’s aides would have had to share passwords in order to access and disseminate the sensitive information.

Via Fox News:

Fox News was told there are several potential scenarios for how classified information got onto Clinton’s server:

Reading intelligence reports or briefings, and then summarizing the findings in emails sent on Clinton’s unsecured personal server.

Accessing the classified intelligence computer network, and then lifting sections by typing them verbatim into a device such as an iPad or BlackBerry.

Taking pictures of a computer screen to capture the intelligence.

Most of these scenarios would require a password. And all of these practices would be strictly prohibited under non-disclosure agreements signed by Clinton and others, and federal law.

The FBI’s investigation into Clinton’s private e-mails really heated up earlier this week when Bryan Pagliano, the IT employee who set up her server and pled the 5th to avoid cooperating with investigators, was granted immunity for cooperating.

That revelation led Judge Andrew Napolitano to declare that Clinton “should be terrified of the fact that he’s been granted immunity.”

Napolitano claims that Pagliano being granted immunity means that Justice Department lawyers want to call him as a witness to testify “against some person or persons north of him on the totem pole.”

Whether or not they only climb high enough on the totem pole to get to Clinton’s aides or the former Secretary of State remains to be seen.
