Ambassadors of the United States are persons nominated by the president to serve as the United States' diplomatic representatives to foreign nations, international organizations, and as ambassadors-at-large. Under Article II, Section 2 of the U.S. Constitution, their appointment must be confirmed by the United States Senate; while an ambassador may be appointed during a recess, they can serve only until the end of the next session of Congress, unless subsequently confirmed.
John Campbell was the acting director of the Office of the Historian within the Department of State. He was appointed to the position in June 2009 and was succeeded as acting director by Edward P. Brynn the same year.
The United States has formal diplomatic relations with most nations. This includes all United Nations members and observer states other than Bhutan, Iran, North Korea and Syria, and the UN observer Territory of Palestine. Additionally, the U.S. has diplomatic relations with Kosovo and the European Union.
