The presidential line of succession is the fixed order of officials who take over the presidency when the President can no longer serve because of death, resignation, removal, or inability to do the job. The Vice President is first. After that come the Speaker of the House and the President Pro Tempore of the Senate, followed by the 15 heads of the executive departments in the order their departments were created.
The Full Order
The complete line runs 18 people deep:
- 1. Vice President
- 2. Speaker of the House of Representatives
- 3. President Pro Tempore of the Senate
- 4. Secretary of State
- 5. Secretary of the Treasury
- 6. Secretary of Defense
- 7. Attorney General
- 8. Secretary of the Interior
- 9. Secretary of Agriculture
- 10. Secretary of Commerce
- 11. Secretary of Labor
- 12. Secretary of Health and Human Services
- 13. Secretary of Housing and Urban Development
- 14. Secretary of Transportation
- 15. Secretary of Energy
- 16. Secretary of Education
- 17. Secretary of Veterans Affairs
- 18. Secretary of Homeland Security
Cabinet members are ranked by the date their departments were established, from the Department of State in 1789 down to the Department of Homeland Security in 2002.1USAGov. Order of Presidential Succession If a person on the list is ineligible, the line skips to the next qualified official.
Where the Order Comes From
Article II, Section 1, Clause 6 of the Constitution gives Congress the power to decide who steps in when both the President and Vice President are unable to serve.2Legal Information Institute. Constitution Annotated – Article II, Section 1, Clause 6 – Succession Clause for the Presidency Congress has used that power three times, passing succession acts in 1792, 1886, and 1947. The current law is the Presidential Succession Act of 1947, codified at 3 U.S.C. ยง 19.3Office of the Law Revision Counsel. 3 USC 19 – Vacancy in Offices of Both President and Vice President; Officers Eligible To Act
The 1947 act was a deliberate change from the previous law. The 1886 act placed Cabinet officers directly after the Vice President and left congressional leaders out. President Truman pushed to reverse that, arguing that elected officials should come before appointed ones. The 1947 act put the Speaker and President Pro Tempore back into the line ahead of every Cabinet member.
A separate piece of the framework is the 25th Amendment, ratified in 1967. It created the procedure for filling a vice-presidential vacancy, so the number-two spot no longer sits empty when the Vice President succeeds to the presidency, resigns, or dies. Before 1967, the vice presidency had been vacant for a combined total of roughly 38 years across American history.4Legal Information Institute. Implementation of the Twenty-Fifth Amendment
Who on the List Actually Qualifies
Being on the list is not the same as being eligible. Anyone who takes over the presidency must meet the same constitutional requirements as an elected President: a natural-born U.S. citizen, at least 35 years old, and a resident of the country for at least 14 years.5Legal Information Institute. U.S. Constitution Annotated – Article II, Section 1, Clause 5 – Qualifications for President A Cabinet secretary who is a naturalized citizen would be skipped.
The 1947 act adds more requirements for Cabinet officers. A department head qualifies only if they were appointed with Senate confirmation before the succession event. Acting secretaries who were never confirmed by the Senate are not successors. A 1985 Office of Legal Counsel opinion reached that same conclusion for acting department heads and recess appointees. Any official under impeachment by the House at the moment the powers would fall to them is also disqualified.6Office of the Law Revision Counsel. 3 U.S. Code 19 – Vacancy in Offices of Both President and Vice President; Officers Eligible To Act
What Congressional Leaders Have to Give Up
The Speaker and the President Pro Tempore face a condition Cabinet members do not. Before either one can act as President, they must resign both their leadership post and their seat in Congress. The statute is explicit: the Speaker must resign “as Speaker and as Representative in Congress,” and the President Pro Tempore must resign “as President pro tempore and as Senator.”7Office of the Law Revision Counsel. 3 USC 19 – Vacancy in Offices of Both President and Vice President; Officers Eligible To Act
The requirement traces to the Incompatibility Clause in Article I, Section 6, which bars anyone from holding a seat in Congress and a federal executive office at the same time.8Constitution Annotated. Incompatibility Clause and Congress The resignation is permanent. A Speaker who steps up cannot return to Congress if the original President recovers.
Becoming President Versus Acting as President
The Vice President is the only one who actually becomes President when succession is triggered. Everyone else on the list “acts as President.” The statute uses that phrase deliberately for the Speaker, the President Pro Tempore, and all 15 Cabinet secretaries.3Office of the Law Revision Counsel. 3 USC 19 – Vacancy in Offices of Both President and Vice President; Officers Eligible To Act
An Acting President exercises all the same powers and receives presidential compensation. But the tenure can be cut short. Under a provision known as “bumping,” if a Cabinet officer is acting as President because everyone higher on the list was unavailable, a higher-ranking official who later becomes available can displace them. There is one exception: if the higher-ranking official was originally unable to serve because of a disability or a failure to qualify, and that obstacle is later removed, the statute says their return does not displace the person currently serving.6Office of the Law Revision Counsel. 3 U.S. Code 19 – Vacancy in Offices of Both President and Vice President; Officers Eligible To Act Bumping has never happened in practice. A President who took office through the Vice Presidency cannot be bumped.
When Succession Has Actually Happened
Nine Vice Presidents have moved up to the presidency. Eight succeeded a President who died in office, and one succeeded a President who resigned:
- John Tyler (1841), after William Henry Harrison died 31 days into his term. Tyler established the precedent that the Vice President becomes the actual President rather than a caretaker.
- Millard Fillmore (1850), after Zachary Taylor died in office.
- Andrew Johnson (1865), after Abraham Lincoln’s assassination.
- Chester Arthur (1881), after James Garfield’s assassination.
- Theodore Roosevelt (1901), after William McKinley’s assassination.
- Calvin Coolidge (1923), after Warren Harding died in office.
- Harry Truman (1945), after Franklin Roosevelt died in office.
- Lyndon Johnson (1963), after John F. Kennedy’s assassination.
- Gerald Ford (1974), after Richard Nixon’s resignation.

An Unresolved Question About Congressional Leaders
Whether the Speaker and President Pro Tempore belong in the line at all is a long-running constitutional dispute. The Succession Clause authorizes Congress to name what “Officer” shall act as President, and a body of legal scholarship holds that members of Congress are not “officers” in the constitutional sense. James Madison took that view. A bipartisan Continuity of Government Commission concluded that “Officers” in the Succession Clause “almost certainly refers to executive branch officials.”
The counterargument notes that the Constitution itself sometimes uses “officers” for legislative officials, and that the very first Congress put legislative leaders in the line in 1792. The Supreme Court has never ruled on the question. Until it does, the 1947 act governs, and the Speaker remains second in line.
