In a controversial move which has deepened political divisions in Washington George Bush has appointed conservative John Bolton as the US ambassador to the United Nations, bypassing the Senate.The President’s Democrat opponents had objected to the nomination of Bolton, a harsh critic of the UN, fearing it would undermine US credibility at the world body. Bush took advantage of a Senate recess to confirm Bolton’s appont. “This post is too important to leave vacant any longer, especially during a war and a vital debate about UN reform. So today I’ve used my constitutional authority to appoint John Bolton as America’s ambassador to the United Nations,” Bush said. Bolton will serve until January 2007 until a new Congress is sworn in. “It will be a distinct privilege to be an advocate for America’s values and interests at the UN, and, in the words of the UN charter, to help maintain international peace and security,” Bolton said. The move was legal but senior Democrat Senator Edward Kennedy called it an abuse of power and “a devious manouevre”.
