The latest in a series of secretly-recorded videos attacking Planned Parenthood was released Thursday. The videos appear to depict executives of the organization discussing the sale of fetal tissue, and make use of graphic footage. The group that created the videos says Planned Parenthood is illegally selling fetal tissue for a profit, a claim Planned Parenthood vehemently denies. The videos have set off a new wave of furor among anti-abortion activists, many of whom protested at the Capitol in Washington, D.C., this week, while Republican lawmakers are making a new push to cut government funding for the organization. But this latest debate over Planned Parenthood has galvanized supporters, too, many defending the use of fetal tissue in medical research. We look at the latest chapter in the fight against Planned Parenthood and abortion rights in America.
