After the extraordinary tumult of Brett Kavanaugh’s confirmation hearings ended, three normal things happened that are embedded in this country’s Constitution and traditions.

The full Senate voted on the nomination, and Judge Kavanaugh was confirmed. Then Supreme Court Chief Justice John Roberts swore in Mr. Kavanaugh as an Associate Justice. Last Tuesday Justice Kavanaugh, sitting as the most junior Justice next to Justice Elena Kagan, participated in oral arguments in two cases involving the Armed Career Criminal Act.
