Chinese researcher claims he helped make first gene-edited babies

A Chinese researcher has created an international controversy over science and ethics after claiming he helped make the world's first genetically-edited babies. According to the AP, the researcher altered embryos for seven couples during fertility treatments. One resulted in the birth of twin girls. The claims have not been independently verified or published in any medical journals where they could be vetted by experts. This kind of gene editing is banned in the U.S. Dr. David Agus joins "CBS This Morning" to discuss the implications of the claims.
