The White House Office is an entity within the Executive Office of the President of the United States (EOP). The White House Office is headed by the White House chief of staff, who is also the head of the Executive Office of the President. The staff work for and report directly to the president, including West Wing staff and the president's senior advisers. Almost all of the White House Office staff are political appointees of the president, do not require Senate confirmation and can be dismissed at the discretion of the president.
The staff of the various offices are based in the West Wing and East Wing of the White House, the Eisenhower Executive Office Building, and the New Executive Office Building. Senior staff, with high level, close contact with the president, have the title Assistant to the President. Second-level staff have the title Deputy Assistant to the President, and third-level staff have the title Special Assistant to the President. These aides oversee the political and policy interests of the president.
