Ambassador Susan Rice was up until recently the American Ambassador to the United Nations. Her long-standing aspiration of becoming the Secretary of State for her country was dashed when the Republicans in the Senate started sharpening their knives in anticipation of her formal nomination for that position by President Barak Obama.
Sensing that her nomination would not scale through the Senate and that she would not be confirmed as Secretary of State due to the role she played in the cover up of the Benghazi affair in which the American Ambassador to Libya, Christopher Stevens, and three other American citizens were murdered by a group of islamist terrorists, her nomination was withdrawn.
