Information and Confrontation in Congressional Oversight

Committees can use oversight hearings to collect and communicate the information Congress needs to oversee the bureaucracy, but many worry that members instead focus on scoring political points by lambasting witnesses. We leverage the collective judgment of congressional staff to measure how exchanges between legislators and witnesses vary on two separable dimensions: information and confrontation. Contrary to the conventional wisdom that confrontation crowds out information, we show that members of the president’s party that engage in less confrontational oversight reveal no more or less information than their peers.
