Background: A few pro-life Democrats had refused to vote for the health care bill yesterday until President Obama signed an Executive Order saying that no federal funds would be used to pay for abortions. And when one of those main Democrats spoke in the House, someone yelled "baby killer!" It looks like it was a Republican from Texan but no one is fessing up.
They are keeping a list of who has denied saying it here.
Edit: We now have our answer. This is the guy who defeated Charles Stenholm (long time Wise County representative before the Republicans gerrymandered his district.)
