If Hillary Clinton wins the presidency in November, the Clinton Foundation will end its affiliation with the Clinton Health Access Initiative, the largest of more than a half dozen charities and initiatives operating under its philanthropic umbrella.

Clinton and her allies have used CHAI’s success in securing low-cost drugs to treat HIV/AIDS as a shield when critics have questioned potential conflicts of interest created by the foundation. According to the Clintons, CHAI has helped 11 million people around the world gain access to life-saving medications.
