If an authorized individual briefs a foreign contingent, can they also send an advance copy of the slides via email?

The guidance around sharing materials, particularly in the context of foreign disclosure, emphasizes the importance of safeguarding sensitive information. Sharing advance copies of presentation materials—regardless of whether they are classified or unclassified—can lead to potential security risks, especially if those materials are not appropriately vetted and sanctioned for dissemination.

The correct answer underscores that advance copies cannot be shared. This policy is in place to maintain control over the information being communicated and to ensure that it is only presented under secure and authorized conditions. When disclosures happen in real-time settings, such as briefings, there is typically a controlled environment where the information can be delivered with the necessary oversight. However, sending materials via email introduces a variety of risks, including unauthorized access and breaches of protocol.

While unclassified documents might seem less risky, it's crucial to adhere to established protocols without exception. The restriction on sharing advance copies is designed to protect not only the integrity of the information but also to uphold national security interests and the terms of any agreements in place regarding the sharing of information with foreign entities.
