Hillary Clinton is launching ads that take credit for a pharmaceutical company’s decision last week to roll back its 4,000 percent price increase of a life-saving drug.

Clinton’s campaign has purchased ads in Iowa and New Hampshire to draw attention to her attack on Turing Pharmaceuticals, a company that drew national scorn for dramatically raising the pricetag of a decades-old drug that’s commonly used to treat AIDS patients.

The price increase was rolled back one day after Clinton accused the company’s CEO of “price gouging” on Twitter.
