The Wall Street Journal is reporting that the Bush administration has begun barring private U.S. AIDS organizations from winning billions of dollars in federal grants to provide health services overseas — unless they pledge their opposition to prostitution. Many AIDS organizations criticized the move saying it will further stigmatize sex workers overseas and make it harder for them to receive AIDS prevention and treatment services. Republicans in Congress are also working to yank federal funding from private groups that advocate or discuss clean-needle exchange programs overseas or from groups that don’t back the president’s push for sexual abstinence.
