So, no unicorn then? Pity.
Take a look at Trump’s reactions every time Mueller makes something public. Trump clearly doesn’t enjoy it much. Trump is also sufficiently distracted (and distractible) that he has lashed out, tantrum-style, against the Fourth Estate.
And he fired Sessions. So, you see, it’s untrue to suggest that the investigation is a sideshow, when it seems capable of derailing the Trump Administration—and that’s not even the intended effect.
No harm in doing both, but you seem to be arguing that there is nothing to be gained from using the institutions of law enforcement and the judiciary against Trump.
You’ve said you’re not a US citizen. That can lead to a feeling of powerlessness watching what we’re going through (like Alaskans feel every two years).
I’m not saying you shouldn’t be concerned—but we are working the problem.
What Mueller did during the lead in the Iraq war is not germane. He’s not running for office. He’s doing his job. Don’t worry about Mueller—just let him do his job, and we’ll keep pressure on in other ways.
