Diana was the chief architect of legislation to expand stem cell research, which was passed twice with broad, bipartisan support in Congress. The measure was vetoed twice by President George W. Bush. In March of 2009, President Barack Obama signed an executive order reversing former President Bush's restrictions on embryonic stem cell research. U.S. Rep. DeGette is working with the Obama Administration on codifying the order into law through the Stem Cell Research Advancement Act, a bill that would ensure a lasting ethical framework overseeing stem cell research at the National Institutes of Health (NIH) and will provide stability to the scientists and individuals who are on the quest for live-saving cures.
