United Nations Issues: Cabinet Rank of the U.S. Permanent Representative [Updated March 23, 2021] [open pdf - 469KB]
From the Document: "The U.S. Permanent Representative is the chief representative of the United States to the United Nations. The President appoints the Permanent Representative with the advice and consent of the Senate. Of the 31 individuals who have served since 1946, about two-thirds have been accorded Cabinet rank by Presidents. Some Members of Congress have demonstrated an ongoing interest in the Cabinet rank of the Permanent Representative in the context of the Senate confirmation process and broader U.S. policy toward the United Nations. On November 24, 2020, President-elect Biden announced his intent to nominate Linda Thomas-Greenfield to be Permanent Representative, with Cabinet rank. Biden stated that he will accord Cabinet status to Greenfield 'because I want to hear her voice on all the major foreign policy discussions we have.' Thomas-Greenfield was confirmed by the Senate on February 23, 2021."
