By being there this week, she showed a lot more guts than the men of that White House. Mr. Meadows, counsel Pat Cipollone and others—her testimony made them sound like a bunch of jabbering hysterics. You tell the president not to do that! No, you tell him! They worried about legal exposure. Ms. Hutchinson paraphrased Mr. Cipollone: “We’re going to get charged with every crime imaginable!”

You get the impression she, on the other hand, was worrying about what was right.

Now alone, with the administration over but its men still hiding, she came forward, and what she said changed everything. Her testimony made criminal charges against the former president more likely. In National Review, former federal prosecutor Andrew McCarthy wrote that her testimony was devastating in that it portrayed Donald Trump as “singularly culpable” for the events of 1/6. As to the disputed limousine fight between the president and his Secret Service agents, Mr. McCarthy says, sensibly: Let them speak under oath. Ms. Hutchinson didn’t say that the skirmish occurred but that she had been told it had—by an agent who was there, minutes after it allegedly happened. There’s nothing wrong in this venue with hearsay. “The point of an investigation is to search for reliable, admissible evidence,” Mr. McCarthy writes. “For that, hearsay is not only allowed but encouraged.”
