Which of the following is NOT a role of the president?

The role of the president encompasses various responsibilities that include being the head of state, chief diplomat, and commander in chief. Each of these roles allows the president to fulfill important functions that are central to the governance of the country.

As head of state, the president represents the nation and is the symbolic figure of its unity and integrity. This role involves various ceremonial duties and the ability to project national identity on a global stage.

In the capacity of chief diplomat, the president manages international relations, negotiates treaties, and appoints ambassadors. This responsibility places the president at the forefront of diplomatic efforts, helping to shape foreign policy and engage with other nations.

The role of commander in chief grants the president authority over the armed forces, empowering them to make critical decisions regarding national defense and military operations.

In contrast, the speaker of the House is a separate position held by a member of the House of Representatives, responsible for overseeing House proceedings and representing the interests of the majority party. This role does not belong to the president and is a distinctly legislative function within the government. Thus, selecting the speaker of the House as the option that is not a role of the president is correct, as it highlights the distinction between the legislative and executive branches of government.
