Prior to fetal viability, a state may regulate abortions just like any other medical procedure -- so long as the regulation in question does not place an "undue burden" on a woman's reproductive rights.

Join Stewart and Doug McKechnie of the U.S. Air Force Academy's law department as they discuss this complex and controversial area of constitutional law.
