Expresses the sense of Congress that: (1) the United States should play a leading role in the drafting and adoption of a thematic United Nations (UN) convention that affirms the human rights and dignity of persons with disabilities that is consistent with the spirit of the American with Disabilities Act of 1990, the U.S. Constitution, and other rights enjoyed by U.S. citizens with disabilities, promotes inclusion of persons with disabilities as foundational requirements for any free society, and provides protections that are at least as strong as the rights recognized under international human rights law for other vulnerable populations; and (2) the U.S. delegation to the UN Ad Hoc Committee meetings should include individuals with disabilities who are recognized leaders in the U.S. disability rights movement.
