Monday was day one of the Democratic National Convention – with a different look and feel due to the coronavirus.

The party will nominate and celebrate their 2020 ticket – former Vice President Joe Biden and Sen. Kamala Harris.

The opening night theme was "we the people" - leaning into an overall unity theme for the Democrats this week.

Bernie Sanders, who battled Biden from the progressive flank during the primary cycle, was among the Monday headliners.

"Donald Trump must be defeated. Biden must be elected. And after that election, we're going to do all that we can to fight for a progressive agenda," says Sanders.

Also appearing Monday was 2016 Republican presidential candidate, John Kasich.

In addition, former first lady Michelle Obama also made an appearance.

Since Harris joined Biden on the ticket, the team has coalesced around certain themes, including the former vice president's ongoing call that 2020 is a battle for the "soul of the nation."

"The choice we make this November is going to decide the future of America for a very, very long time," says Biden.

However, at the campaign's core is trying to persuade voters they're best equipped to lead the United States out of the coronavirus pandemic.

Biden and Harris are expected to be in Milwaukee Thursday to accept their nomination.
