A U.S. Defense Department contract linguist has been charged with giving classified information, including the names of American intelligence assets, to a Lebanese national with ties to the Iran-back terrorist group Hezbollah, the Justice Department in Washington announced Wednesday.

Thompson was due in court later Wednesday for an initial appearance. She was arrested last week on the espionage-related allegation.

“While in a war zone, the defendant allegedly gave sensitive national defense information, including the names of individuals helping the United States, to a Lebanese national located overseas,” said Assistant Attorney General for National Security John C. Demers. “If true, this conduct is a disgrace, especially for someone serving as a contractor with the United States military. This betrayal of country and colleagues will be punished.”

The investigation leading to this arrest revealed that starting on or about December 30, 2019, a day after U.S. airstrikes against Iranian-backed forces in Iraq, and the same day protesters stormed the U.S. embassy in Iraq to protest those strikes, audit logs show a notable shift in Thompson’s network activity on United States Department of Defense classified systems, including repeated access to classified information she had no need to access.

Specifically, during a six-week period between December 30, 2019, and February 10, 2020, Thompson accessed dozens of files concerning human intelligence sources, including true names, personal identification data, background information, and photographs of the human assets, as well as operational cables detailing information the assets provided to the United States government.

A court-authorized search of Thompson’s living quarters on February 19, 2020, led to the discovery of a handwritten note in Arabic concealed under Thompson’s mattress.

The note contained classified information from Department of Defense computer systems, identifying human assets by name, and warning a Department of Defense target who is affiliated with a designated foreign terrorist organization with ties to Hezbollah. The note also instructed that the human assets’ phones should be monitored.

Thompson transmitted the classified information in the handwritten note to a co-conspirator, in whom she had a romantic interest. The FBI’s investigation revealed that Thompson knew the co-conspirator was a foreign national whose relative worked for the Lebanese government. The investigation also revealed that the co-conspirator has apparent connections to Hezbollah.

Further investigation revealed that, in a separate communication, Thompson also provided information to her co-conspirator identifying another human asset and the information the asset had provided to the United States, as well as providing information regarding the techniques the human assets were used to gather information on behalf of the United States.
