What was in emails between hussein and Hillary" What about Biden and Hillery? What sort of pictures did hillary and Huma send each other via email? What reporters did Hillary exchange emails with? How many Clinton Foundation donors also exchanged emails with Hillary? How many different email accounts were on that server? How many different client devices accessed that server? etc, etc, etc.
Endless.
I do not think Obama was included in the emails on her server. I think they wanted the personal server to keep a lot of the messages secret from him.
