Yes, it could really spiral into a nightmare. There's Chinese businessman/acquaintance that Andrew grew close to for several years. It was revealed that the guy a high ranking member of the Communist Party and it was suspected he was spying. (I don't think there's any suspicion, but that was what was reported) What sensitive info might have been passed along by Andrew?
Between the entire Epstein scandal and Andrew's habit of passing along Govt. info to his "friends", it's a huge balloon of scandal. I'm sure the true facts of both scandals will not be known for years.
It goes down to Andrew's ego and greed.
