I will just note that:
Public servants have a general duty, as well as a specific legal responsibility, to hold in confidence the information that may come into their possession in the course of their duties. This duty and responsibility are exercised within the framework of the law, including in particular any obligations of the Government to...protect [information] from disclosure under [certain] statutes such as the Privacy Act.
And that:
Officials must...respect their obligation as public servants not to disclose classified information or other confidences of the Government to those not authorized to receive them.
