Susan Elizabeth Rice (born November 17, 1964) is a U.S. public servant who served as the 24th United States National Security Advisor from 2013 to 2017. She was formerly a U.S. diplomat, Brookings Institution fellow, and U.S. ambassador to the United Nations. She served on the staff of the National Security Council and as Assistant Secretary of State for African Affairs during President Bill Clinton's second term. She was confirmed as UN ambassador by the U.S. Senate by unanimous consent on January 22, 2009.
Rice's name was mentioned as a possible replacement for retiring Secretary of State Hillary Clinton after President Barack Obama's re-election in 2012, but on December 13, 2012, following ongoing controversy related to the 2012 attack on the U.S. consulate in Benghazi, she announced that she was withdrawing her name from consideration, saying that if nominated "the confirmation process would be lengthy, disruptive, and costly".
Rice succeeded Tom Donilon as National Security Advisor on July 1, 2013. Wikipedia
