Congressional oversight mainly involves which of the following actions?

Congressional oversight primarily involves the investigation of executive actions to ensure accountability and compliance with laws and regulations. This power allows Congress to review, monitor, and supervise federal agencies and programs, examining how executive branch officials implement policies and spend public funds. Through hearings, reports, and investigations, Congress can assess whether the executive is executing laws as intended, and it can address potential abuses of power or inefficiencies.

By carrying out oversight, Congress upholds its responsibility to represent the interests of the public and maintain checks and balances within the federal government. This action is critical to ensuring transparency and accountability, making it a fundamental aspect of the legislative function.
