After President Bush vetoed the embryonic stem cell funding bill (that had bi-partisan support in Congress, but not enough to override the veto), I thought it would be nice to hear from an actual scientist on this issue. So, I invited Professor Steven Teitelbaum onto my show this afternoon. He’s one of the top experts on stem cells, having done years of work in that field at Washington Univeristy, and explained in layman’s language why Bush was wrong.
