Although it is the Executive Branch’s responsibility to prosecute law breaking, Congress’ legislative responsibilities include the authority to investigate private sector corruption, negligence, misinformation, and other forms of malfeasance or failures. Congressional investigations of the private sector shine a light on specific problems within the American economy and institutions and can reveal holes in existing laws or regulations. Consequently, these hearings can contribute to policy formation and efforts to enact legislative reforms. Some examples of Private Sector Oversight hearings include those related to the financial dealings of the Enron Corporation, the lack of transparency in the tobacco industry, and steroid use in professional sports.
