From the Freedom of the Press Foundation:

In one of his last public talks, to a room full of more than 200 journalists, Daniel Ellsberg was asked what the media could do to better support whistleblowers. In a passionate speech, Ellsberg implored the crowd, and the press in general, to investigate the U.S. government’s classification system. As he explained, our democratic society is making a serious mistake “in not investigating the secrecy system, covering how it acts, how it works, and how it keeps secrets and what secrets it keeps.”
