What function does the Office of Inspector General (OIG) serve?

The Office of Inspector General (OIG) primarily serves the function of investigating and preventing fraud and misconduct within federal agencies. This role is critical to maintaining accountability and integrity in government operations. The OIG conducts audits, investigations, and evaluations of agency programs and activities to ensure that resources are being used effectively and ethically.

By focusing on identifying vulnerabilities and overseeing adherence to laws and regulations, the OIG helps to safeguard public trust and promote transparency in government practices. This function is essential for deterring fraudulent activities and addressing any misconduct, thereby reinforcing the overall efficacy and reliability of governmental agencies.

The other options, while related to governmental functions, do not align specifically with the core responsibilities of the OIG. Overseeing IT initiatives, managing public engagement strategies, and supporting legislative affairs fall under the purview of different offices or divisions within federal agencies that focus on technology management, public communication, and governmental relations, respectively.
