WASHINGTON (AP) - A House Republican has said that there is a low rate of pregnancy among women who are raped, stirring up an issue that proved politically toxic for another Republican.

Arizona Republican Trent Franks was speaking at a House Judiciary Committee hearing on his bill that would ban abortions after 20 weeks of pregnancy when he said that the incidence of rape resulting in pregnancy is low.

That brought a quick retort from California Democrat Zoe Lofgren who said Franks' comment lacked scientific basis.

Franks' office said he was saying that later-term abortions that result from rape are infrequent.

Former Rep. Todd Akin saw his 2012 campaign for a Senate seat in Missouri founder after he said that women's bodies can avoid pregnancy in cases of "legitimate rape."
