A prominent cancer-treatment foundation is ending its work with Planned Parenthood, a decision Planned Parenthood called "deeply disturbing and disappointing."
The Susan G. Komen for the Cure Foundation has broken off a partnership through which it provided cancer screenings at Planned Parenthood clinics, The Associated Press reported Tuesday. Planned Parenthood blamed the political controversy over abortion rights.
Planned Parenthood said its clinics provided about 4 million screenings for breast cancer over the past five years, roughly 170,000 of which were supported by Komen grants.
Planned Parenthood said it has established an emergency fund to offset the loss of the Komen funds.
Komen told the AP that it ended its partnership with Planned Parenthood because of a congressional investigation into the organization. Republicans on the House Energy and Commerce Committee have requested detailed financial records from Planned Parenthood.
