The Obama administration will introduce its first statement calling for the United Nations' top human rights body to combat discrimination against gays and lesbians around the world, completing a U.S. reversal on the subject during the presidency of George W. Bush.

The U.S. declaration will be made Tuesday at the Geneva-based Human Rights Council and has the support of more than 80 countries. Although it is not in the form of binding resolution, the American push for U.N. action has helped win over a handful of new countries to the cause. A resolution could be brought to a vote later this year.

The issue of gay rights has polarized nations at the U.N. for years. And despite growing acceptance for homosexuality in Western nations and parts of Latin America, lawyers say there is still a gap in human rights treaties for the protection of gays against discrimination and mistreatment.
