In the U.S. government, the president actually assumes the responsibilities of the "prime minister" of most other countries, and the position that most closely resembles the "prime minister" among other officials is the White House Chief of Staff, which can also be translated as the White House Chief of Staff. He is the highest-ranking official in the Executive Office of the President of the United States and a senior aide to the President of the United States, leading the operations of the White House Office. The White House chief of staff is a position with a lot of power, often referred to as "the second most powerful person in Washington", and even some people call it the US prime minister.

The Executive Office of the President (abbreviated as EOP), also translated as the Office of the President, is a general term for the personal staff of the President of the United States, as well as the assistants and agencies directly responsible to the President, and its structure began in 1939. The current unification is led by the White House Chief of Staff.

Historically, there were few staff members of the early U.S. presidents, and in the 19th century, President Thomas Jefferson had only 1 courier and 1 secretary, both of whose salaries were paid by the president personally. White House assistants in 1900 included 1 "presidential secretary," 2 assistant secretaries, 2 administrative scriveners, 1 stenographer, and 7 other staff members. Beginning in 1939 during President Roosevelt's second term, the situation changed dramatically. New presidential executive bodies are constantly being created through decrees or executive orders of the President. The most important include the Council of Economic Advisers (1946), the National Security Council (1947), the Office of the United States Trade Representative (1963), the Council on Environmental Quality (1970), the Office of Science and Technology Policy (1976), and the Office of National Drug Control Policy (1989). The Office of the President's Executive Has become a sprawling institution with a budget of hundreds of millions of dollars and thousands of employees.
