From Secrecy News:
Government officials were reminded recently that as they depart from government service with the end of the current Administration, they are not permitted to take classified information with them.
“Classified information is not personal property and may not be removed from the Government’s control by any departing official or employee. This includes ‘extra’copies.”
That timely warning (pdf) was issued by William J. Bosanko, the director of the Information Security Oversight Office, which oversees the national security classification system.
