Editorial: Trump’s latest frivolous lawsuit, against Clinton and others, should cost him

Former President Donald Trump — whose various slanders against his real and perceived political foes made him the most libelous president ever to hold the post — is now suing Hillary Clinton and others who highlighted his suspicious behavior toward Russia during and after the 2016 presidential campaign. If and when Trump submits to being deposed by the defendants, we’ll believe this is something more than his usual empty bluster. If that doesn’t happen (prediction: it won’t), Trump should be on the business end of a major frivolous-litigation judgment.
