Many Republican lawmakers and other groups are speaking out against President Obama's executive order, allowing the federal government to fund controversial stem cell research.
Congressman Chris Smith, (R) New Jersey, held a news conference in Washington DC Monday, along with representatives from the U.S. Conference of Catholic Bishops and the Family Research Council.
Smith and other lawmakers say stem cell research is unethical because it destroys human embryos.
"President Obama has chosen to turn back the clock," said Smith. "And starting today, will force taxpayers to subsidize the unethical, over the ethical, the unworkable over what works, and hype and hyperbole over hope."
Others who are opposed say stem cell research is unreliable and there are more effective alternate research methods available.
