The stated duties of the secretary of state are to supervise the United States
foreign service and
immigration policy and administer the Department of State. The secretary must also advise the president on U.S. foreign matters such as the appointment of diplomats and ambassadors, advising the president of the dismissal and recall of these people. The secretary of state can conduct negotiations, interpret, and terminate treaties relating to foreign policy. The secretary also can participate in international conferences, organizations, and agencies as a representative of the United States. The secretary communicates issues relating to the U.S. foreign policy to Congress and citizens. The secretary also provides services to U.S. citizens living or traveling abroad such as providing credentials in the form of passports. Doing this, the secretary also ensures the protection of citizens, their property, and interests in foreign countries. Secretaries of state also have domestic responsibilities. Most of the historical domestic functions of the Department of State were gradually transferred to other agencies by the late 19th century as part of various administrative reforms and restructurings. Those that remain include storage and use of the Great Seal, performance of
protocol functions for the
White House, and the drafting of certain proclamations. The secretary also negotiates with the individual states over the extradition of fugitives to foreign countries. Accordingly, the resignations of President
Richard Nixon and of Vice President
Spiro Agnew were formalized in instruments delivered to then-Secretary of State
Henry Kissinger. Although they have historically decreased over time, Congress may occasionally add to the responsibilities of the secretary of state. One such instance occurred in 2014, when Congress passed the Sean and David Goldman International Child Abduction Prevention and Return Act which mandated actions the secretary of state must take in order to facilitate the return of abducted children from nations who are party to the
Hague Convention on the Civil Aspects of International Child Abduction. As the highest-ranking member of the cabinet, the secretary of state is the third-highest official of the
executive branch of the U.S. federal government, after the president and vice president, and is fourth in
line to succeed the presidency, after the
vice president, the
speaker of the House of Representatives, and the
president pro tempore of the Senate. Six past secretaries of state
Jefferson,
Madison,
Monroe,
John Quincy Adams,
Van Buren and
Buchananhave gone on to be elected president. Others, including
Henry Clay,
Daniel Webster,
Lewis Cass,
John C. Calhoun,
John M. Clayton,
William L. Marcy,
William Seward,
Edward Everett,
Jeremiah S. Black,
James Blaine,
Elihu B. Washburne,
Thomas F. Bayard,
John Sherman,
Walter Q. Gresham,
William Jennings Bryan,
Philander C. Knox,
Charles Evans Hughes,
Elihu Root,
Cordell Hull,
Edmund Muskie,
Alexander Haig,
John Kerry,
Hillary Clinton, and
Marco Rubio have also campaigned as presidential candidates, either before or after their term of office as secretary of state, but were ultimately unsuccessful. The position of secretary of state has therefore been viewed to be a consolation prize for failed presidential candidates. == Timeline of secretaries of state ==
