This year, Roe Day doesn’t quite feel like a celebration. To mark the occasion and with our eyes on the future, Ms. asked abortion rights supporters in the House of Representatives to share what the anniversary of Roe means this year in particular, how they see their role in the larger fight for abortion rights, how Congress can act as a counterbalance to a Supreme Court prepared to overturn Roe, and what they wish they could tell anti-abortion lawmakers standing in their way.
