President Biden’s stash of classified documents reportedly included material marked top-secret, the nation’s highest classification level.
The highly classified material was recovered among approximately 10 classified documents at Mr. Biden’s think tank in the fall, a federal official familiar with the investigation told CBS.
Top secret material could pose “exceptionally grave damage” to national security if leaked.
Fewer than 10 classified documents were discovered at Mr. Biden’s residence in Wilmington, Del., bringing the total number of classified documents to approximately 20 between the two locations.
None of the documents recovered from Mr. Biden’s residence were marked top secret.
