What was NY Times vs US?

Answer 1

This was the famous Pentagon Papers case. The New York Times came into possession of a huge amount of documents about the war in Vietnam and sought to publish it. The US government sought to pevent the publication by threatening legal action because the Papers were still classified as secret so the Times sued to get a judgment confirming its right to print the Papers under the right of freedom of the press. The US Supreme Court ruled that the the government could not restrain the Times from publishing the Pentagon Papers prior to publication. As it turned out, much of the Pentagon Papers contained little true classified information. They were more of a political embarassment than publication of secrets.
