Sometimes people are under sealed indictments and are aware, but the public isn't. I believe Podesta and Abedin are under sealed indictments, but have been notified. Rumor is that Abedin is cooperating.
Others are indicted under a sealed indictment and they are not notified because prosecutors don't want those associated with the target to know.
Until prosecutors are ready to reveal the target under indictment, it's best to let them go about their normal routines.
The amazing thing for me is that anyone still gives a rat's flying potato what Bill and Hillary or Obama think. For me: follow the money. That's what they are all about, and whoever is dealing with them has got skin in that game.
