What mechanisms does the constitution provide to control presidential power?

The U.S. Constitution establishes several mechanisms to control presidential power, primarily through the system of checks and balances. Congress has the authority to legislate, approve budgets, and conduct oversight, which limits the executive's power. Additionally, the Senate must confirm presidential appointments and ratify treaties, while the judiciary can review executive actions for constitutionality. Furthermore, the impeachment process allows Congress to remove a president for misconduct.
