DNC Day 2: Here's what to expect from the second day of the Democratic convention

Washington — Democrats from across the country are returning Tuesday to Chicago's United Center and McCormick Place for Day 2 of the Democratic National Convention as the party continues to rally around its new ticket. 

The convention's kickoff day featured a surprise appearance and brief remarks from Vice President Kamala Harris, the party's new nominee, who took the moment to celebrate President Biden ahead of his keynote address. 

Mr. Biden, who opted to leave the race less than a month ago, delivered an energetic — and at times emotional — speech to cap the first day of the convention where he spanned his five-decade-long career, lauded his accomplishments in office, and heaped praise on Harris as he passed her the torch.
