As thousands of pro-life activists journey to Washington, D.C. this week, we talked with one of the most effective advocates for pro-life policies and initiatives in the history of the movement, Susan B. Anthony List president Marjorie Dannenfelser. Marjorie talks about how she went from being pro-choice to pro-life, the feminist argument for protecting the unborn, meaningful changes to adoption and workforce policies to ease the challenges of unexpected pregnancies, and the political game plan for pro-life advocates if the Supreme Court overturns Roe vs Wade.

Marjorie Dannenfelser is president of Susan B. Anthony List and the author of "Life is Winning: Inside the Fight for Unborn Children and Their Mothers." Follow Marjorie on Twitter at @marjoriesba.
