The most useful class I ever took in college was a media law class, where I learned two things: 1) Journalists in the U.S. (along every other American citizen) have enormous freedom to say and write what they want, without fear of a defamation suit and 2) this freedom exists largely because of New York Times v Sullivan, a seminal Supreme Court case.

Now NYT v Sullivan is under concerted attack, from a group that includes wealthy and powerful people and companies; lawyers who see an opportunity; and, of course, Donald Trump.

David Enrich, an editor who oversees business investigations at the Times, gets to do his work in large part because of the court precedent set decades ago. His upcoming book Murder the Truth takes us on a tour of incidents that show what losing NYT v Sullivan could mean for journalism in the U.S. — and how powerful people are already chipping away at press freedom.
