The Bush administration has been posting hundreds of highly confidential U.N. audits and investigation reports on a U.S. government Web site, opening the United Nations' inner workings and some of its more colorful scandals to unusual public scrutiny. Together, the nearly 500 documents and thousands of pages constitute a trove of U.N. secrets stretching back over five years, including allegations of bribes paid for tsunami relief projects in Indonesia, of sexual harassment in Gaza and a revelation that a U.N. anti-drug official ran a presidential campaign while receiving a U.N. paycheck. The pages also document a spree of alleged criminal activities, including a bribery scheme at the airport in Pristina, Kosovo, gold trading by U.N. peacekeepers in Congo, and the theft and resale of food rations by Ukrainian pilots serving the United Nations in Liberia. Mark D. Wallace, the U.S. representative for U.N. management and reform, has posted 477 documents. Most of the names of those targeted in the reports have been redacted by the United Nations, but the identities are easily deciphered. For years, the United Nations has guarded the confidentiality of its audits, saying they are meant as constructive criticism for managers. Their disclosure by the United States has generated a mixed reaction from U.N. officials: One said it was ironic that an administration that has placed such a premium on secrecy would be so transparent about the United Nations.
