"As you are well aware, the Classified Information Non-Disclosure Agreement, which you attached to your letter, invites, but by no means requires Mr. Owen to submit materials for pre-publication review. Although the Sensitive Compartmented Information Nondisclosure Statement does require pre-publication security review under certain circumstances, that obligation is expressly limited to specifically identified Special Access Programs. That agreement was executed in January 2007, and the Special Access Programs to which it applies were identified on that date. Accordingly, it is difficult to understand how the matter that is the subject of Mr. Owen’s book could conceivably be encompassed by the non-disclosure agreement that you have identified."
