What it says is bad enough. Those agencies are independent for a reason. They're not supposed to be the president's political agents. Loss of that independence is a serious, damaging thing.

Next question: Why does Trump want control of those agencies? General principles? People around him told him to? Ego (proving that he's the Big Man In Charge)? Or does he actually intend to use that power? If so, for what?

This is a big deal. This is reducing the US federal government's ability to competently govern, and that's going to hurt, in concrete ways, before too long. If this stands, we're going to regret it.

If. I still have hope for the court system to overturn this.
