[JURIST] In an effort to bolster support for UN ambassador nominee John Bolton [official website], the State Department Friday released endorsements and letters of support for Bolton from former secretaries of state, ambassadors and senior government officials. The endorsements come two days after the Senate Foreign Relations Committee [official website] decided to delay its vote on his nomination [JURIST report] after Democrats requested more time to question former officials who worked with Bolton. Bolton, the current Under Secretary of Arms Control and International Security and a harsh critic of the UN political and judicial system, has come under attack by those who accuse him of being a "serial abuser" of lower-level officials who challenge his views. Secretary of State Condoleezza Rice reiterated her support for Bolton in a speech [text] Friday, and said he would be a strong advocate for instituting much-needed changes in the world body. The Bolton committee vote is now expected Tuesday. CNN has more.
