Anyone have a full list of who they are counting as either the 8 or 13 in that quote? According to Wikipedia, the number of people who have been charged under the espionage act is much higher than 13. For example, there are 52 pages of people convicted under the act.[1] I guess it depends on your definition of "leaking". The relevant dictionary definition of leak is "to give out (information) surreptitiously".[2] Giving information to a foreign government should seemingly be classified as leaking so I'm not sure we should necessarily link it to either journalistic endeavors or whistleblowing.
