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.
Bernard Siegel (attorney)
In both 2003 and 2004, Siegel played a pivotal role in protecting a form of stem cell research in the United Nations, which was under the threat of being banned by world treaty. In 2003, he brought some of the world’s most prominent stem cell research scientists together at a meeting at the U.N. to educate delegates about the need to ban human reproductive cloning (the cloning of a whole person) while keeping nuclear transfer research (for the cloning of stem cells) legal throughout the world. That very year, the U.N. avoided the passage of a treaty that would have banned nuclear transfer research worldwide by a single vote. In 2004, the treaty was downgraded to a nonbinding resolution that left the matter of whether or not to allow nuclear transfer up to the various nations.
