Those are the issues on which the media have focused.
As I've outlined above there are other laws that were also necessarily broken as a result, name the Hatch Act which prohibits using government accounts for electioneering and the Official Records Act. The ORA is similar too slightly different than FOIA. FOIA requires the government to release records to the public in certain circumstances. ORA requires you to send copies of all official records to the National Archives and defined what constitutes a record. So ORA is broader than FOIA.
