MRC’s Ken Shepherd notes that CBS’s The Early Show this week offered balance in its treatment of embryos and stem cell research in its two part series, “Two Faces of Hope,” but came short of fully delivering. Monday’s installment by Hattie Kauffman centered on Cody Unser, a paralyzed stem cell research advocate, with no critics allowed talking head time to cast doubt on the promise of embryonic stem cell research. Tuesday’s mostly positive portrayal of frozen embryo adoption by correspondent Tracy Smith, however, featured a critic of embryo adoption, as well as Smith asking her story’s subjects, J.J. and Tracy Jones, if they had allowed their adopted son to be used as a “political pawn” at a White House event they attended in May which encouraged embryo adoption.
