If you have contact with an agent of a foreign power, you're required to report the encounter and what you talked about.
I'm not really sure how agents, or contact, are defined. I think the law is intended to keep IC people honest and forthcoming about foreign attempts to turn people.
(Disclaimer: I have never held a security clearance.)
Intriguing. People with a security clearance are required to give intelligence reports about people they have contact with?
