I did not know Priebus well. He often seemed both confused and irritated, and it was not hard to imagine why. Running the Trump White House would be a difficult job for even an experienced manager, which Priebus wasn’t. Previously chairman of the Republican National Committee and before that a Wisconsin lawyer, Priebus had never served in the federal government. How could someone like that—or anyone, for that matter—manage someone like Donald Trump? I have no idea. But Priebus seemed to be trying.
