Today over two dozen experts in science, medicine, law and ethics released an open letter to news media and the people of Missouri on the state's proposed ballot initiative known as Amendment 2. They conclude that "the people of Missouri should know what they are actually voting on. Amendment 2 creates a constitutional right for researchers to engage in human cloning. Efforts to deny this are misleading and deceptive."

The signers include experts in embryology, microbiology and maternal/fetal medicine, as well as past and present members of the President's Council on Bioethics and several founding members of Do No Harm: the Coalition of Americans for Research Ethics.
