President Bush Vetoes Stem Cell Legislation

June 20, 2007


President Bush has vetoed the Stem Cell Research Enhancement Act (S.5). The AAN sent a letter to President Bush in April urging him to sign S. 5 into law.

The Stem Cell Research Enhancement Act would have allowed federal funding for research using stem cells derived from human embryos originally created for fertility treatments and willingly donated by patients. S. 5 differs from previous versions of this bill because it also includes language that requires the National Institutes of Health (NIH) to research and fund methods for creating embryonic stem cell lines without destroying embryos. Only five percent of existing stem cell lines (21 of more than 400) may currently be used in federally funded research, limiting the ability of American researchers to pursue pioneering stem cell research.

The bill will now be returned to the Congress. Bill supporters in the Senate currently do not have enough votes to override the President’s veto.
