“Classified documents can never be taken out of a (sensitive compartmented information facility), ever.”
There are scenarios in which classified documents can be removed from a sensitive compartmented information facility, also known as a SCIF. It’s a physical space that meets intelligence community protocols that allows officials with the proper security clearance to study classified documents. Sensitive compartmented information facilities are used typically for materials categorized as "top secret/sensitive compartmented information." There are differing levels of classified documents, with escalating levels of security clearances required to view them. Not all classified documents must be viewed in a SCIF.
