Tommy Thompson, the former head of the Department of Health and Human Services under President Bush who is running as a Republican for Wisconsin’s open Senate seat, is defending himself against claims that he has flip-flopped on embryonic stem cell research and abandoned his previous support for the field.
The scrutiny came after Thompson delivered a speech at an international adult stem cell conference jointly organised by the Vatican’s Pontifical Council for Culture and the US-based Stem for Life Foundations, in which he touted the value of adult stem cell research while seeming to diminish embryonic stem cell research.
