Probably. Unless Huber kicks into gear then maybe the point becomes moot.
IGs are spread across all levels of the Executive branch. Horowitz is DOJ IG (FBI under DOJ so he has them too). Most IG reports are based on single issue topics. Horowitz has a bunch (lost count) we just saw the 1st major (Q called it LITTLE) one.
Most IG reports don't get congressional hearings. Only when it's high visibility and grandstanding opps are available do they have hearings.
But, Huber/IG combo is legal but groundbreaking which clouds things. So, events might outpace Congress' ability to have hearings.
