Yes, but how is it not noticed by those around him? You’d have to think people around him would be able to figure out who’s part of the team. He has to meet with them some time so anyone with close access to Trump who pays attention to his daily schedules would likely have suspicions. Maybe there’s just one point of contact between Trump and the rest of the team? Who knows?
Never should have had that weasel Bolton in there or Coats, Esper, etc. Coats caused a lot of DS to be put in positions.
There’s a lot you can do “in the tank” as they called the FBI SCIF in The Americans. Sh!t would happen and all the top dogs would go running for the tank and slam the door shut behind them.
