This argument totally misses the context of that appointment, which was the tremendous pressure Trump was under from the Democrats and DC establishment after he fired Director Comey. Trump appointed Director Wray, yes, but the appointment was made basically under duress. It was hardly his choice, and he was under immense political pressure to assuage the optics of what looked like a coverup in his firing of Comey. He had to choose someone recommended by uniparty politicians like McConnell.
