Final answer:
The most severe limit on presidential power is impeachment and removal from office, a two-step process involving the House's formal accusation and the Senate's trial.
Step-by-step explanation:
The most severe limit on presidential power is impeachment and removal from office. This process involves two steps: first, the House of Representatives impeaches, or formally accuses, the president of wrongdoing. If impeached, the president then faces a trial in the Senate, and if found guilty, is removed from office.
The most severe limit on presidential power is impeachment and removal from office. Impeachment is the process by which the House of Representatives brings formal charges against the president for wrongdoing, and if found guilty in a trial overseen by the Senate, the president can be removed from office. This check on presidential power ensures that a president who has been elected by the entire country can be held accountable for any misconduct.
This severe check on presidential power ensures that a president who has been elected by the entire country can only be removed by a deliberative process involving elected officials from both houses of Congress. Other limitations such as Senate approval over presidential appointments and the ability of Congress to overturn presidential vetoes also exist, but the power of impeachment is the most direct and significant method to curtail a president's power.
