"Now, more than ever, our nation is in need of prayer for the protection of the unborn and the dignity of all human life," Archbishop Naumann said in a statement. "I am happy to be joined by bishops in dioceses across the country who are hosting pro-life prayer events including during the overnight hours of Eucharistic adoration. I invite all Catholics to spend time with our Lord and join in this nationwide vigil for life."
