Catholic League president William A. Donohue has written the chair of the National Institutes of Health Human Embryo Research Panel to voice the League’s strong objections to proposed research.

He compared the present proposals to risky medical procedures performed decades ago on African-Americans and to current concerns being voiced over the suffering of animals involved in medical research.

“Those who are undecided on the status of the human embryo,” Dr. Donohue said, “ought to have learned by now that doubt is sufficient grounds for saying no to another round of questionable medical research.”
