Answer:
D. while the number of oversight hearings has increased over time as the bureaucracy has expanded, the extent of oversight does depend somewhat on which party controls the White House
Step-by-step explanation:
In politics, oversight refers to the failure for government officials to notice the mistakes that occurred in their job. When the white house is controlled by different parties, their priorities tend to be really different over the opposition party. Because of this, only the oversight for programs that are not aligned with their parties' platform tend to be increased.
