@revelette2,
Interesting.
The FBI doesn't either confirm or deny such investigations as a matter of policy.
The FBI has acknowledged generally that it is "working on matters related to former Secretary Clinton's use of a private e mail server"
"The FBI has not publicly acknowledged the specific scope, focus, or potential targets of any such proceedings."
Translation:
1. If there was an investigation ongoing the FBI wouldn't ascknowledge it.
2. There is something (let's call it an inquiry or proceeding ) ongoing with respect to Hillary's private e mail server.
3. The FBI will not confirm the scope, target or extent of that proceeding.
