The President’s Cabinet is built around fifteen executive departments, each led by a Senate-confirmed secretary (the Department of Justice is the exception, headed by the Attorney General). The list of departments in the Cabinet is fixed by federal statute at 5 U.S.C. § 101, and it has stood at fifteen since the Department of Homeland Security was added in 2002.1Office of the Law Revision Counsel. 5 USC 101 – Executive Departments The Constitution never uses the word “Cabinet,” but Article II, Section 2 lets the President demand written opinions from “the principal Officer in each of the executive Departments,” and George Washington turned that authority into a working advisory body almost immediately.2Constitution Annotated. Article II Section 2 Only Congress can add or remove a department from the statutory list.
The Fifteen Executive Departments
The departments below appear in the order they were created. That sequence matters for more than history: it also sets the order of presidential succession among cabinet officers under 3 U.S.C. § 19.1Office of the Law Revision Counsel. 5 USC 101 – Executive Departments
State (1789)
Handles foreign affairs, runs U.S. embassies and consulates abroad, and negotiates treaties. The Secretary of State is first in line among cabinet officers for presidential succession.

Defense (1947)
Oversees the armed forces and military strategy. It succeeded the Department of War, which had been established in 1789.
Justice (1870)

Why the Order of Departments Matters
The chronological order above is also the order in which cabinet secretaries sit in the presidential line of succession. Under 3 U.S.C. § 19, if the President, Vice President, Speaker of the House, and President pro tempore of the Senate are all unable to serve, the Secretary of State is next, followed by Treasury, Defense, and so on down to Homeland Security.6Office of the Law Revision Counsel. 3 USC 19 – Vacancy in Offices of Both President and Vice President7USAGov. Order of Presidential Succession
One constitutional filter applies. Any secretary who would step into the presidency must be a natural-born citizen, at least 35 years old, and a U.S. resident for at least 14 years.8Constitution Annotated. Article II Section 1 Clause 5 – Qualifications If a secretary doesn’t meet those qualifications, the line skips to the next eligible person. Naturalized citizens have served as cabinet secretaries in several administrations and are passed over in the succession order regardless of seniority.
Officials With Cabinet Rank Who Don’t Lead a Department
The President can grant “cabinet rank” to officials who do not head any of the fifteen statutory departments. They attend cabinet meetings and advise the President, but they are not listed in 5 U.S.C. § 101 and do not appear in the presidential line of succession.1Office of the Law Revision Counsel. 5 USC 101 – Executive Departments Which positions receive this designation changes from one administration to the next.
The Vice President and the White House Chief of Staff are standing members of every modern cabinet. Beyond those two, recent administrations have elevated officials such as the Administrator of the Environmental Protection Agency, the Director of the Office of Management and Budget, the U.S. Trade Representative, the Director of National Intelligence, the CIA Director, the Administrator of the Small Business Administration, and the Ambassador to the United Nations. With the exception of the Vice President and Chief of Staff, most of these positions still require Senate confirmation even though the offices they lead are not executive departments.
How Department Heads Are Chosen
The Appointments Clause in Article II, Section 2 requires the President to nominate department heads “by and with the Advice and Consent of the Senate.”9Constitution Annotated. Overview of Appointments Clause The White House submits the nomination, the relevant Senate committee holds public hearings to vet the candidate’s background and potential conflicts of interest, and the committee votes on whether to send the nomination to the full Senate.
A simple majority confirms.10United States Senate. About Voting Since 2013, executive-branch nominations cannot be filibustered, so a nominee needs 51 votes, or 50 plus the Vice President’s tiebreaker. Once confirmed, the nominee is sworn in and takes charge of the department.
Cabinet secretaries then serve at the pleasure of the President. The Supreme Court held in Myers v. United States (1926) that the President’s duty to see that laws are faithfully executed carries with it an unrestricted power to remove executive officers, with no Senate vote, formal hearing, or stated cause required.11Justia. The Removal Power That authority is what distinguishes cabinet secretaries from officials whose removal Congress has protected by statute, such as certain independent agency heads.
