Stem cell laws and policy in the United States
In May 2005, the House of Representatives voted 238-194 to loosen the limitations on federally funded embryonic stem-cell research — by allowing government-funded research on surplus frozen embryos from in vitro fertilization clinics to be used for stem cell research with the permission of donors — despite Bush's promise to veto if passed.  On July 29, 2005, Senate Majority Leader William H. Frist (R-TN), announced that he too favored loosening restrictions on federal funding of embryonic stem cell research. On July 18, 2006, the Senate passed three different bills concerning stem cell research. The Senate passed the first bill, 63-37, which would have made it legal for the Federal government to spend Federal money on embryonic stem cell research that uses embryos left over from "in vitro" fertilization procedures. On July 19, 2006 President Bush vetoed this bill. The second bill makes it illegal to create, grow, and abort fetuses for research purposes. The third bill would encourage research that would isolate pluripotent, i.e., embryonic-like, stem cells without the destruction of human embryos.
Governorship of Mitt Romney
During his 2002 campaign, Romney had expressed broad support for embryonic stem cell research, and said he would lobby President Bush (who the year before had banned most federal funding for such research) to support it. In particular, Romney stated that he supported the use of surplus embryos from fertility clinics for stem-cell research. In early 2005, Romney announced his position on therapeutic cloning for the first time, saying he was against it, but was still in favor of research on unused embryos from fertility treatments. Per this stance, he vetoed a Massachusetts bill to fund stem-cell research because the legislation allowed such cloning of human embryos. "I am not in favor of creating new human embryos through cloning," said Romney, calling the practice "a matter of profound moral and ethical consequence". Romney also opposed the legislation because of its assertion that life does not begin until an embryo is implanted in a uterus. "It is very conceivable that scientific advances will allow an embryo to be grown for a substantial period of time outside the uterus," Romney said in an interview with the "Boston Globe". "To say that it is not life at one month or two months or four months or full term, just because it had never been in a uterus, would be absurd." The state legislature overrode Romney's veto, with many legislators feeling that stem-cell research will be important in the future to the state's biotech industry.
