[JURIST] Thousands of abortion opponents marched on Washington Monday, commemorating the 32nd anniversary of the Supreme Court's decision in Roe v. Wade which fell Saturday. In a phone call from Camp David [US Newswire transcript] President Bush addressed the March for Life [event website] rally, stating that "this movement will not fail." Every anniversary of the January 23 decision prompts demonstrations by both proponents and opponents of abortion rights.

Wade decision. Pro-Choice America released a report [official website] this month which projects that 38 states would outlaw abortion if the decision were overturned.
