WASHINGTON (BP)--President Obama reaffirmed his support for abortion rights on the 36th anniversary of the Roe v. Wade ruling. In a written statement released two days after his inauguration, Obama said Jan. 22 he remains "committed to protecting a woman's right to choose." The anniversary reminds Americans the 1973 Supreme Court opinion "not only protects women's health and reproductive freedom, but stands for a broader principle: that government should not intrude on our most private family matters," he said. The president issued his declaration of support for abortion rights on a day when tens of thousands of pro-life advocates gathered in Washington for the annual March for Life. Young people made up much of the crowd, which rallied on the National Mall before walking up Constitution Avenue to the Supreme Court building.
