Regardless of who is president.
The hearings process &al for cabinet officers and others is absurd, this is not the way we staff management positions in organizations now. Perhaps it made sense in the 18th century, but I doubt it - this is one area the framers had just about zero experience in.

These are the president's creatures & the president is responsible for them. Of course if they are corrupt or incompetent the legislature should have the power to remove and disqualify them even if the president adores them. But it might point to a presidential problem more than anything else.
