A child with diabetes and a paralyzed 23-year-old joined Democratic presidential candidate Hillary Rodham Clinton on Friday in urging US President George W. Bush to loosen restraints on money for embryonic stem cell research. Clinton addressed the issue just days after the US House voted to ease limits on the federally funded research despite Bush's threat of a veto. Bush says the legislation would compel taxpayers to support "the deliberate destruction of human embryos" for the research. Lawmakers lack the votes to overturn a veto. Embryonic stem cells are prized because they can develop into all types of tissue. Joining Clinton at Dartmouth College were Alex Walter, 10, who has Type 1 diabetes, and Laura Clark, who has been paralyzed since a car crash three years ago.
