Bernie Sanders Vows to Continue His Political Revolution as Thousands Plan to Attend People's Summit

Democratic presidential candidate Bernie Sanders addressed supporters in a live webcast Thursday night and vowed to continue what he called his political revolution. He did not endorse former Secretary of State Hillary Clinton, but said he will work with her to defeat the presumptive Republican nominee Donald Trump. As thousands plan to attend a People’s Summit in Chicago to discuss the next steps of Sanders’ revolution, "Democracy Now!" speak with a key participant, RoseAnn DeMoro, head of National Nurses United, the first national union to back Sanders last year. Sanders recently tried to place her on the Democratic platform committee, but said he was blocked by the Democratic National Committee.
