The private emails of Hilary Clinton obtained by the FBI are being reviewed by the US Capitol in very secure rooms by lawmakers and select staff from congressional committees under a strict protocol controlled by one set of documents. 

However, the Office of Senate Security have a copy, investigators with security clearance have looked at the documents, it is not known how many lawmakers have seen them. The documents were made available to the Judiciary, Homeland Security, Appropriations committees and both sides of the Intelligence committees have copies. Are the documents still considered 'secret'?
