Bush vetoes stem cell research legislation

President Bush quickly vetoed a Senate bill that would lift restrictions on federally funded human embryonic stem cell research.

The measure would have provided millions of dollars to a field of medical research that is controversial because it requires destroying human embryos to extract cells. Supporters of the legislation have claimed that expanded stem cell research might help fight many costly diseases of aging, including diabetes, Parkinson's disease, Alzheimer's disease, Lou Gehrig's disease and other maladies.

It was Bush's first veto since he has been in office. He had repeatedly said he would not approve government funding for research using embryonic stem cell colonies.
