Following the series of “sting videos” aimed at Planned Parenthood and produced by the Center for Medical Progress, state legislatures and the House of Representatives opened a series of investigations targeting Planned Parenthood. While the investigations have found no wrongdoing on the part of Planned Parenthood, CMP’s videos have had a profound effect on legislation: state legislatures in Florida, Indiana, Ohio and Arizona have taken aim at cracking down on fetal tissue research. That research, Politico reports, is vital to developing a potential Zika vaccine and understanding Zika-related birth defects like microcephaly.
