what is the function of the secretary general of the united nations
Secretary-General of the United Nations The Secretary-General was envisioned by U.S. President Franklin D. Roosevelt as a "world moderator", but the vague definition provided by the United Nations Charter left much room for interpretation. The Secretary-General is the "chief administrative officer" of the UN (Article 97) "in all meetings of the General Assembly, of the Security Council, of the Economic and Social Council and the Trusteeship Council, and shall perform other functions as are entrusted to him by these organs" (Article 98). They are also responsible for making an annual report to the General Assembly. They may notify the Security Council on matters which "in their opinion may threaten the maintenance of international peace and security".
United States Ambassador to the United Nations The U.S. Permanent Representative, currently Nikki Haley, is charged with representing the United States on the U.N. Security Council and during almost all plenary meetings of the General Assembly, except in the rare situation in which a more senior officer of the United States (such as the U.S. Secretary of State or the President of the United States) is present. Like all United States ambassadors, he or she must be nominated by the U.S. President and confirmed by the Senate.
