24 CFR 15.107 - How does HUD handle requests that involve classified records?
If your request involves the release of documents that are classified under Executive Order 12958, HUD will refer your request and the pertinent documents to the originating agency for processing according to the requirements of § 15.104(a). HUD may refuse to confirm or deny the existence of the requested information if the originating agency determines that the fact of its existence is itself classified.
