Without courting attention or even familiarizing Americans with the sound of his voice, Robert Mueller became a celebrity , portrayed by Robert De Niro on “Saturday Night Live,” and a potent political symbol: of the stubborn hope for truth and justice if you believed in his cause; of the indefatigable persecution of Donald Trump if you bought the president’s deceits and delusions.

So, yes, his appearance on Capitol Hill on Wednesday — hours of remarks from a man who has barely spoken in public since the start of his investigation into the Trump campaign’s ties to Russia — is a big moment. But that’s not the same as a game-changing one. And anyone rightly aghast at this presidency and righteously desperate to move past it needs to recognize that Mueller’s testimony probably isn’t even the beginning of the end.

It should be. That’s obvious from his report, unexamined by most voters. It makes clear that while officials with the Trump campaign didn’t huddle with Vladimir Putin over vodka and blinis to scrawl a to-do list — Column A for the Kremlin, Column B for Javanka — their attitude about help from Moscow was: Here’s the Trump Tower address! Use the far-right elevator in the lobby. Wait, wait, you have emails? Out with them, fast! It’s not digital theft. Merely glasnost for the age of Assange.

And while Trump may not have dispatched goons to kneecap Mueller, he made plenty of other attempts to interfere, impede and intimidate. A vivid, colorful recitation of those efforts would be damning.
