It all started a month ago, when the anti-abortion group Center for Medical Progress began releasing a series of videos alleging to show a Planned Parenthood doctor discussing the illegal sale of fetal tissue to activists posing as biomedical researchers. 

Planned Parenthood denied any wrongdoing, but the videos created an opening for political opponents. Governors and legislators in more than a dozen states either launched or called for official inquiries into the activities of regional affiliates. Guess what they found? Not much — though that hasn’t changed GOP rhetoric.
