Some months later OIG filed a report challenging the rule the Arkansas office had applied, reporting that they had had approval from Washington for this dubious action. Big embarrassment when I had to admit to my boss, a very nice guy, I was the one who had screwed up. After that learning experience I tried to remember the lesson and to teach it to my employees when I moved back into management.
Long story short: Evan Osnos, a very good writer in the New Yorker, has this paragraph on Trump's phone call with the president of Taiwan:
"For a piece I published in September, about what Trump’s first term could look like, I spoke to a former Republican White House official whom Trump has consulted, who told me, “Honestly, the problem with Donald is he doesn’t know what he doesn’t know.” It turns out that is half of the problem; the other half is that he has surrounded himself with people who know how much he doesn’t know."
