Dr. Richard G.A. Feachem, head of the Global Fund to Fight AIDS, Tuberculosis and Malaria, has used hundreds of thousands of dollars in Fund cash for limousines, cruises and four-star meals, in addition to his $320,000 tax-free salary, according to a report released by the Global Fund’s inspector general. Global Fund spokesman Jon Liden countered that the report was inaccurate, although he did not dispute many of the charges.
