From Hugo Black (1886 -1971), American politician who served as a Democratic United States Senator and represented Alabama in the Senate from 1927 to 1937, and served as an Associate Justice of the Supreme Court of the United States from 1937 to 1971, from his concurring opinion in the Pentagon Papers case, New York Times Company v. United States (1971):
In the First Amendment, the Founding Fathers gave the free press the protection it must have to fulfill its essential role in our democracy. The press was to serve the governed, not the governors. The Government’s power to censor the press was abolished so that the press would remain forever free to censure the Government. The press was protected so that it could bare the secrets of government and inform the people.
