The term "leaked" as a connotation of being hacked or stolen. These are not like Hillary's leaked emails. These were released via due process - exactly how public figures' emails are supposed to be public.
Its also good to point out this is exactly why Hillary had a private email server.
Reminder: we all have the power to get information released through FOIA. When I have a chance I will post a request template. I work in govt and see these all the time.
