The President is routinely outraged at the shenanigans going on in his administration, but why do these things keep happening? Why is he not more on top of things? Why does the president learn about scandals in his administration through the media just like the rest of us?
Perhaps he's so detached from the nuts and bolts of governance that he just lets people do what they want and then when they embarrass him he professes to be "as angry as anyone", which anger eventually cools to "phony scandal", which ultimately dissipates to "Dude, that happened two years ago."
When you spend most of your tenure as CEO of the country on the golf course or global sightseeing you're probably going to miss a lot of what's actually happening in the government you're supposed to be running.
