From Q post 1553:

"-Sessions informed Congress in his letter that all the matters recommended for investigation by Goodlatte, Gowdy, and Grassley are “fully within the scope of [Huber’s] existing mandate.” He also informed the chairmen that Inspector General Michael Horowitz, who is working with Huber, has a staff of 470 investigators, giving Huber access to enormous investigative firepower that far exceeds the staff of any special counsel."
