The Democratic National Convention begins Monday in Chicago with roughly 50,000 people expected to arrive in the Windy City. That includes thousands of anti-war activists who plan to demonstrate near the United Center where Vice President Kamala Harris will officially accept the party’s nomination for president.

Earlier this month, delegates made Harris their nominee in a virtual roll call. The party will still conduct a ceremonial roll call vote at the convention mimicking the look of a traditional roll call where state delegations announce their votes from the convention floor.
