Don't Sweat the Details! Enhancing Congressional Committee Expertise Through the Use of Detailees

In contrast to the dramatic growth in the size and influence of the executive branch over the past 40 years, congressional committee staffing levels are at an all-time low. Faced with growing demands to produce legislation and to conduct oversight of executive branch policymaking, Congress can and does supplement its existing staff by borrowing personnel, known as detailees, from federal agencies. Using an original dataset of detailees from 1997 to 2015, we analyze the degree to which congressional committees rely on detailees to increase legislative capacity. We find that committees in the House and Senate use detailees in different ways to further both legislative and oversight initiatives.
