A pre-abortion sonogram bill is one step closer to becoming law. The Texas House of Representatives voted yesterday to approve its version of the bill. It would require a doctor to perform a sonogram on a woman before providing an abortion. The doctor would have to display the image, explain it and make audible the heartbeat. The senate passed a similar measure, but it allows a woman to choose not to see the images or hear the sounds if her pregnancy is the result of rape, incest or if the fetus has an irreversible medical condition. Both sides still have to agree on a final version of the law.
