When will they learn? Yet another Republican lawmaker has come forward to profess his belief that rape rarely results in pregnancy. “The incidence of rape resulting in pregnancy are very low,” said Arizona Rep. Trent Franks during a committee hearing on Wednesday. Franks introduced a bill to ban abortions after 20 weeks and was reacting to an amendment offered by Democrats that would carve out an exception for rape and incest victims. Rep. Zoe Lofgren, a Democrat from California, responded to Franks by saying there was no scientific basis for his claim.
