John Bolton–President Bush’s pick to be ambassador to the United Nations–is facing new accusations of misconduct during his time at the State Department. The Washington Post is reporting today that Bolton often blocked then-Secretary of State Colin Powell and, on one occasion, his successor, Condoleezza Rice, from receiving information vital to U.S. strategies on Iran. Sources told the Washington Post of a dozen examples of memos or information that Bolton refused to forward during his four years as undersecretary of state for arms control and international security.
