My wife works for a little nondescript USDA federal office. Whenever a new president from a different party gets elected, the current higher ups lose their jobs and the president installs his people.
And this is for a little office in Wisconsin. Why Trump didn't do this sooner, I'll never know.

He's lazy and it's a lot of work replacing everyone.
Besides, an IG is not a political appointment. These are the watchdogs of the system. Trump's firing of IG's is absolutely NOT draining the swamp. It's removing oversight in his administration. In other words, he's putting more "yes men" into positions of power. Those who will do his bidding and not rat out his illegal actions and self dealing.
