The media has panned Donald Trump’s First Amendment lawsuits against Facebook, Twitter and YouTube: “sure to fail,” “as stupid as you’d think,” “ridiculous.” Mr. Trump’s complaint omits important precedents, facts and claims for relief, but there’s a strong case to be made that social-media censorship violates the Constitution. If his lawyers do better in court than in their initial filing, Mr. Trump can win.
It’s true that the First Amendment ordinarily applies to the government rather than private companies. But the central claim in Mr. Trump’s class-action lawsuit—that the defendants should be treated as state actors and are bound by the First Amendment when they engage in selective political censorship—has precedent to back it up.
