President Bush announced, on August 9, 2001 that federal funds, for the first time, would be made available for hESC research on currently existing stem cell lines; however, the Bush administration chose not to permit research on hESC cell lines not currently in existence, thus limiting federal funding to research in which "the life-and-death decision has already been made"[29]. The Bush Administration's guidelines differ from the Clinton Administration guidelines which did not distinguish between currently existing and not-yet-existing hESC. Both the Bush and Clinton guidelines agree that the federal government should not fund hESC research that directly destroys embryos.Neither Congress nor any administration has ever prohibited private funding of embryonic research. Also, public and private funding of adult stem cell research has no restriction whatsoever.
