There is no sign the controversy will end anytime soon.
Republicans on the presidential campaign trail have seized on the issue. A key backer of Republican former Sen. Rick Santorum caused a stir Thursday by suggesting a novel birth control method for women.
"Back in my days, they used Bayer aspirin for contraceptives," Foster Friess, a Wyoming multimillionaire who is bankrolling a super political action committee for Santorum, told an astonished Andrea Mitchell on MSNBC. "The gals put it between their legs and it wasn't that costly."
The response — which Friess delivered with a smile — came as Mitchell asked him whether he agreed with Santorum's stance on social issues, including women in combat and contraceptives.
