[JURIST] Fifty-nine former US diplomats have sent a letter to US Senate Foreign Relations Committee [official website] chairman Richard Lugar, calling on the Senate to reject the nomination of John Bolton for US ambassador to the United Nations [US Mission to the UN official website]. Saying Bolton "is the wrong man for the position," the former diplomats who signed Tuesday's letter cited Bolton's "exceptional record" of opposing US efforts to improve national security through arms control and Bolton's "insistence that the UN is valuable only when it directly serves the United States." Bolton's nomination [JURIST report; State Department press release] earlier this month was met with surprise [JURIST report] by Senators on both sides of the aisle. The Senate Foreign Relations Committee will hold a hearing [meeting notice] on Bolton's nomination on April 7. AP has more.
