“It is unclear what country the foreign agent worked for and exactly what kind of information was allegedly leaked by the career serviceman.”
This is like when they don’t show a picture of a criminal or tell you the race of the perpetrator. My guess this means it’s a “friendly” country, and the “friendly” country that spies on us the most is Israel.
Or perhaps there is no real foreign agent and the FBI created the whole situation...
Another possibility is that the “foreign agent” is just a broker who sells secrets to the highest bidder.
I understand that is a lucrative line of work for those who have the necessary contacts.
