In what its supporters hailed as a milestone in the U.S. commitment to fighting the global spread of HIV/AIDS, the Senate approved by voice vote a five-year, $15 billion anti-AIDS package in the pre-dawn hours of May 15th. But Africa and anti-AIDS activists complained after the vote that the bill retained serious flaws and warned that the $15 billion provided by the package still faces a number of legislative and executive obstacles before the money can actually be spent. "This bill is a check given to countries fighting AIDS, but it will come back marked 'insufficient funds'," noted Paul Zeitz, executive director of the Global AIDS Alliance.
