Updated August 22, 2013The US Congress has wrestled with the issue of presidential succession throughout our history. Why? Well, between 1901 and 1974, five vice presidents have taken over the top office due to four presidential deaths and one resignation. In fact, between the years 1841 to 1975, more than one-third of all U.S. presidents have either died in office, resigned, or become disabled. Seven vice presidents have died in office and two have resigned resulting in a total of 37 years during which the office of vice president was completely vacant.
The Presidential Succession System
Our current method of presidential succession takes its authority from:
- The 20th Amendment (Article II, Section 1, Clause 6)
- The 25th Amendment
- The Presidential Succession Law of 1947
The 20th and 25th Amendments establish procedures and requirements for the vice president to assume the duties and powers of the president if the president becomes permanently or temporarily disabled.
In the event of the president's temporary disability, the vice president serves as president until the president recovers. The president may declare the beginning and ending of his or her own disability. But, if the president is unable to communicate, the vice president and a majority of the president's Cabinet, or "...other body as Congress may by law provide..." may determine the president's state of disability.
Should the president's ability to serve be disputed, Congress decides. They must, within 21 days, and by a two-thirds vote of each chamber, determine whether the president is able to serve or not. Until they do, the vice president acts as president.
The 25th Amendment also provides a method for filling a vacated office of the vice president. The president must nominate a new vice president, who must be confirmed by a majority vote of both houses of Congress.
In October, 1973, Vice President Sprio Agnew resigned and President Richard Nixon nominated Gerald R. Ford to fill the office. in August, 1974 President Nixon resigned, Vice President Ford became president and nominated Nelson Rockefeller as the new vice president. Although the circumstances that caused them were, shall we say, distasteful, the transfers of vice presidential power went smoothly and with little or no controversy.
Beyond the President and Vice President
The Presidential Succession Law of 1947 addressed the simultaneous disability of both the president and vice president. Under this law, here are the offices and current office holders who would become president should both the president and vice president be disabled. Remember, to assume the presidency, a person must also meet all the legal requirements to serve as president.
1. Vice President of the United States
2. Speaker of the House of Representatives
3. President pro Tempore of the Senate
The secretaries of the president's Cabinet now fill out the balance of the order of presidential succession:
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 & Human Services
13. Secretary of Housing & Urban Development
14. Secretary of Transportation
15. Secretary of Energy
16. Secretary of Education
17. Secretary of Veterans' Affairs
18. Secretary of Homeland Security
