The movement for a ban got a significant boost Tuesday when Sen. Bill Frist, R-Tenn., said he would support the cloning ban legislation, which the Senate is expected to debate in the weeks ahead.

"Many are overpromising on the science" benefits that are possible from cloning, Frist told reporters. He also said creating a human embryo "for reason of experimentation leads to destruction of that embryo and to me that is morally unacceptable."
