Michelle Obama, Oprah At Women's Conference In Long Beach

The third day of the Women's Conference delivered an impressive roster of powerful women to the speaker's podium. First ladies Michelle Obama and Laura Bush addressed the conference, as well as Dr. Jill Biden. Oprah and former Supreme Court justice Sandra Day O'Connor were among five women to receive the Minerva Award, which was followed by a special performance by Sarah McLachlan.

Also during the conference, Matt Lauer challenged Meg Whitman and Jerry Brown to take down their negative ads. In a panel titled "Men Who Get It," Brian Williams led a discussion with Phil Knight of Nike, Howard Schultz of Starbucks, and Nick Kristof of the New York Times about men's roles in advancing women's issues. In the keynote address, Maria Shriver took to the stage to share her story about her initial reluctance at being a candidate's spouse, the death of her mother, and finding peace by acknowledging that "it's okay to not know what to do next."
