Which of the following requires a prepublication review?

Requiring prepublication review for submitting information to Congress is related to safeguarding sensitive information and ensuring that classified or controlled information is not inadvertently disclosed. This process serves as a protective measure to prevent unauthorized disclosures that could compromise national security or sensitive operations.

When submitting information to Congress, which can be public or confidential depending on the context, it's crucial to have oversight and approval to ensure compliance with legal and regulatory requirements. This guarantees that any information shared does not include classified or sensitive details that could harm national interests or violate applicable laws.

In other scenarios, such as publishing a personal blog, sending a memo, or speaking in social gatherings, the communication does not typically involve formal reviews, as they either concern personal views or internal discussions that do not require stringent oversight regarding classified information.
