“In 2017, however, law enforcement officers discovered that Birchum had removed more than 300 classified files or documents, including more than 30 items marked top secret, from authorized locations to his home, his overseas officer’s quarters, and a storage pod in his driveway.

Prosecutors say Birchum had two documents on a thumb drive in his home that contained information relating to the National Security Agency’s capabilities and methods of collection, and targets’ vulnerabilities. Both documents were classified as Top Secret/SCI, and their unauthorized release could be expected to cause “exceptionally grave damage to the national security of the United States.” the U.S. attorney’s office said in a statement.”
