WASHINGTON -- White House bioethics advisers were weighing the benefits of medical advances against the moral hazards of human cloning, a day after President Bush challenged the group to be the "conscience of the country."
The President's Council on Bioethics planned to dive into the details of human cloning on Friday. There is considerable support in Congress to ban the cloning of a human being for purposes of creating another human, but lawmakers are divided on cloning cells for research and medical treatment.
Even as his advisers were deliberating, Bush repeated his opposition to all human cloning Thursday, but said the group can serve an important role in helping Americans understand the issue.
"I have spoken clearly on cloning. I just don't think it's right," Bush told the council, which met with him at the White House. "On the other hand, there is going to be a lot of nuance and subtlety to the issue, I presume. And I think this is very important for you all to help the nation understand what this means."
Bush created the council, a mix of ethicists, doctors, lawyers and philosophers, after wrestling with whether to allow federal funding for research that used stem cells derived from embryos. He said he hopes the group will help as he faces similar balancing acts in the future.
"I really think you can help be the conscience of the country," he said.
Bush said it would help people like him understand how to come to grips with how medicine and science interface with the dignity of life, "and the notion that ... there is a creator."
The 18-member council will examine stem cell research, as well as euthanasia and assisted reproduction, typically in vitro fertilization.
To date, no one has cloned a human, which would be the genetic equivalent of a twin brother or sister born later. But scientists have cloned several animals, and last fall, researchers announced they had created a human embryo clone to provide stem cells for research.
The House has already passed a ban on human cloning and the Senate may take up the issue as soon as this spring. Council chairman Leon Kass predicted the council may have a recommendation by summer.
Many in the Senate favor a ban that excludes research and medical treatments that do not involve implanting a cloned embryo into a woman's uterus.
Opponents argue that this sort of treatment would involve destroying the newly created embryo, which they say is a human life on its own, and could lead to more objectionable forms of cloning.
