Sen. Bernie Sanders, Sen. Elizabeth Warren and first lady Michelle Obama are among those scheduled to speak during the the Democratic National Convention's first night. Protests by Bernie Sanders' supporters inside and outside the convention venue have clouded calls for unity. And the fallout over a Wikileaks release of party emails continued, with Debbie Wasserman Schultz deciding not to gavel in the convention. Earlier, some Sanders supporters booed loudly whenever Hillary Clinton's name was mentioned, and Sanders has since asked his delegates "to not engage in any kind of protest or demonstration on the convention floor," saying that the resignation of Schultz "is a very positive sign."
