Aha, I had forgotten... absolutely, Dong the defector, who went directly to Defense Intelligence, and the FBI and CIA didn’t even know about this existence for what, a few months????
Yes. I think Jingwei came to the US in January 2021, or possibly December 2020, but the news about him didn’t break until July 2021. I imagine he was providing information before 2021 though, if for no other reason than to prove his bona fides.
