I can believe there might not be a “client list” on company letterhead labeled as such. But there is plenty of evidence that would allow interested investigators and journalists too, for that matter, to put together a list of close associates. If you filter out the one-time passengers, one-time visitors, they could put together a map of his associates. It’s possible to determine the cell phone numbers of visitors to the island; just like they did for the January 6 people.
It’s possible to interview all these people, and including staff and security folks.
Then if you study his finances, you’ll get a more complete picture. The point is, you have to build the client list. Sounds like a job for FBI to me.
WSJ has done just that...............
