Mary Ziegler

Legal historian Mary Ziegler has chronicled the legal, political and cultural battles around abortion, and says the debate is far from over: "We're at a moment of almost unprecedented uncertainty in the United States when it comes to abortion," Zielger says. Her book is Roe: The History of a National Obsession.

Law professor Mary Ziegler explains how the anti-abortion movement upended the GOP establishment and helped push the courts to the right. Her new book is Dollars for Life.
