I suppose we should start with CONGRESS and their IT Spy from Pakistan and don’t forget FineSwines Chinese Spy....
I'd bet a kidney that both scenarios were arrangements, meant to allow for the open transfer of information/intelligence with a wrapper to claim ignorance if/when it blew up or went public.
Has any agency/agent looked into money/asset transfers to the key persons and those around them? How about security checks on the "hired help"? Were they screened or were the screenings waved?
Consider what we commoners go through to open a bank account, obtain a mortgage, purchase a gun; how were these spies allowed to be in positions to access secret/sensitive information AND political figures?
