In this Saturday, Oct. 16, 2010 file photo, some of an estimated 45,000 people participate in the Susan B. Komen Race for the Cure in Little Rock, Ark. The nation's leading breast-cancer charity, Susan G. Komen for the Cure, is halting its partnerships with Planned Parenthood affiliates in 2012 - creating a bitter rift, linked to the abortion debate, between two iconic organizations that have assisted millions of women. Planned Parenthood says the cutoff, primarily affecting grants for breast exams, results from Komen bowing to pressure from anti-abortion activists. Komen says the key reason is that Planned Parenthood is under investigation in Congress - a probe launched by a conservative Republican who was urged to act by anti-abortion groups.
