Minority Leader Nancy Pelosi found herself defending abortion rights at her weekly news conference Thursday, one day after House Republicans pulled a bill banning abortions after 20 weeks, saying it is not up to politicians in Washington to decide an issue the Supreme Court has ruled on. “The life and the health of the mother is what is preeminent in when a decision is made about women’s reproductive health,” Pelosi said. “It isn’t an ideological fight, it’s a personal health issue. And as a mother of five in six years, I have great standing on this issue, great understanding of it, more than my colleagues.”
