John Robert Bolton (born November 20, 1948) is an American attorney, political commentator, Republican consultant, former diplomat and national security advisor.
Bolton was the United States Ambassador to the United Nations from August 2005 to December 2006 as a recess appointee by President George W. Bush. He resigned at the end of his recess appointment in December 2006 because he was unlikely to win confirmation from the Senate, of which the Democratic Party had gained control at the time. In later years, Bolton was the U.S. National Security Advisor under the Trump administration from April 2018 to September 2019.
Bolton is a former senior fellow at the American Enterprise Institute (AEI), and Fox News Channel commentator. He was a foreign policy adviser to 2012 presidential candidate Mitt Romney. Bolton has been involved with numerous conservative organizations, including the anti-Muslim Gatestone Institute, where he was the organization Chairman until March 2018, and as a Director of the Project for the New American Century, which favored going to war with Iraq.
