More than to 50,000 participated, organizers estimated. Pope Benedict XVI's representative to the United States, Archbishop Carlo Maria Vigano delivered a message from the pope along with his papal blessing. Pope Benedict's message, which was also sent out on a Vatican Twitter feed, said, "His Holiness is grateful to all those who take part in this outstanding public witness to the fundamental human right to life and to the moral imperative of upholding the inviolable dignity of each member of our human family, especially the smallest and the most defenseless of our brothers and sisters." "You are a powerful witness that God's truth cannot be silenced," said San Francisco Archbishop Salvatore J. Cordileone, who blessed participants to begin the event. "Yes, we are here to stay because life is good and life is holy." The speakers at the Walk included Lacey Buchanan, the mother of a disabled child; Elaine Riddick, who was forcibly sterilized by the state of North Carolina at age 14; Kelly and Matthew Clinger who regret their abortions; and the Rev. Clenard Childress, Jr., who has spoken at nearly every Walk since its founding in 2005. "Truth is rising up and you are the picture of that truth," said Rev. Childress to loud cheers. "We will not draw back until every child is free."
