John Robert Bolton is an American lawyer and diplomat who has served in several Republican administrations. Bolton served as the U.S. ambassador to the United Nations from August 2005 until December 2006 as a recess appointee by President George W. Bush. He resigned in December 2006, when the recess appointment would have otherwise ended, because he was unlikely to win Senate confirmation. Bolton is currently a senior fellow at the American Enterprise Institute, a Fox News Channel commentator, and of counsel to the Washington, D.C. law firm Kirkland & Ellis. He was a foreign policy adviser to 2012 presidential candidate Mitt Romney. Bolton is also involved with a number of politically conservative think tanks and policy institutes, including the Jewish Institute for National Security Affairs, the Project for the New American Century, the Institute of East-West Dynamics, the National Rifle Association, the U.S. Commission on International Religious Freedom, the Council for National Policy and the Gatestone Institute, where he serves as the organization Chairman.
