How about the WaPo? Those 2 outlets, after all, initially published the Pentagon Papers in 1971:
The study comprised 3,000 pages of historical analysis and 4,000 pages of original government documents in 47 volumes, and was classified as "Top Secret - Sensitive" ("Sensitive" is not an official security designation; it meant that access to the study should be controlled)The study, which included cables, presidential memos, and field memos from Vietnam, was not officially declassified until 2011.
As many of us know, Daniel Ellsberg and Anthony Russo copied and then leaked the Papers. They were both prosecuted under the Espionage Act. The charges against them were ultimately dismissed b/c of illegal government break-ins and wiretapping that fell under the rubric of the scandal commonly known as "Watergate."
What's fascinating in the present context, however, is that there is no record of any gov't searches or seizures of journalists in this time frame. The Nixon WH, whose name lives on in infamy for its secrecy, civil liberties violations, and overall heavy-handedness, did go to court in a vain attempt to prevent publication--a major controversy at the time. It never, however, went after any person (e.g. NYT reporter Neil Sheehan) or entity who ultimately published the Papers.
It should be recalled that, at the time of the leak in 1971, over 150,000 American troops were still actively involved in a war in Vietnam. There was also that Cold War thingy w/ the Soviets. The pursuit of those who published these leaks, however, was apparently never considered by the wonderful folks who gave us the Plumbers even w/ that (undeclared) war going on.
Perhaps that historical context will provide relevant guidance today.
