Congress's ability to investigate the executive branch serves what purpose?

Congress's ability to investigate the executive branch serves to limit presidential power by ensuring oversight and accountability. This investigative power allows Congress to examine the actions and decisions of the executive branch, which is vital in maintaining the system of checks and balances that is foundational to the U.S. government. Through investigations, Congress can uncover any misuse of power or illegal actions, providing a mechanism for restraint on executive authority.

While Congress does indeed create laws and confirm executive appointments, these functions are separate from the investigative role. Additionally, the dismissal of Congress members falls under other procedures like elections or expulsion for misconduct rather than being related to investigations of the executive branch. Thus, the essential role of investigations emphasizes Congress's responsibility to oversee the executive's actions and protect democratic principles.
