I don’t even see a justification for the need to put these departments more closely under the control of the executive

False corruption charges are frequently used by insurgencies and foreign influence operations to undermine legitimate governance. I’m not saying it is or isn’t a legitimate concern in this case but, if it were, we definitely wouldn’t know the exact reasons. Given Russia’s history of using foreign influence as a weapon of war and, in particular, their history of doing so in Ukraine, I can definitely understand the concern.

Of course real corruption can’t go unanswered because of the possibility of trumped up charges. It’s a tricky bit of business to get right.
