Which position serves the president directly as part of the White House staff?

The position that serves the president directly as part of the White House staff is Special Assistants. This role is crucial because Special Assistants are typically tasked with managing specific areas of responsibility, providing direct support to the president on various issues. They often have specialized knowledge or experience that allows them to advise the president effectively and help streamline the decision-making process.

Special Assistants can focus on a wide range of topics, from policy development to communications and logistics, depending on their area of expertise. This close working relationship allows them to influence the administration's agenda and ensure that the president's directives are carried out efficiently. The role is designed for those who operate at the highest levels of governmental operations, thus positioning them as key contributors to the president's daily functions and overarching strategies.

Other positions mentioned, such as Counselors or Decision-makers, may also work closely with the president but do not fall under the direct classification of White House staff in the same way that Special Assistants do. Commissioners typically refer to officials in various agencies or divisions and do not serve in the same direct advisory capacity.
