U.S. Senate candidate Elizabeth Warren of Massachusetts will speak in a headlining role at the Democratic National Convention, the Obama campaign said Monday. A rising star in the Democratic Party, Warren will speak in primetime just before former President Bill Clinton, who will enter President Obama’s name into the nomination. Of the prime speaking slot, Warren said, "It will be an honor to share the convention stage with President Clinton on Wednesday, and to talk about what is happening to America's families."
