Trump’s social media lawsuit isn’t about the law. It’s about politics.

With flags rippling and cameras rolling, flanked by his staff and loyalists, Trump took to a lectern to decry what he called “social media companies’ shameful censorship of the American people.” That the lectern was at his golf club in Bedminster, N.J., rather than in the White House Rose Garden was hardly noticeable. He was back in the spotlight, inveighing against powerful interests on behalf of freedom-loving Americans. The news conference cast Trump in his favored role of righteous, aggrieved crusader against elite institutions — in this case, big tech companies, which Americans of both political parties have grown to mistrust.
