The Democratic presidential candidate went after the former Florida governor at a campaign event Tuesday night in Denver. She seized on his questioning of federal spending on women's health at a forum in Tennessee earlier in the day.
Bush's campaign said he had been trying to criticize funding of Planned Parenthood. Clinton says that was just as bad.
Clinton also jabbed Bush on immigration, saying he supports policies that expose families to possible deportation. Bush has taken the most dovish stance in the Republican field on the issue and called for legal status for many people in the country illegally.
Clinton attended three fundraisers in Colorado during a busy campaign day.
