(NEXSTAR) – After celebrating President Joe Biden’s achievements and Hillary Clinton’s historic campaign on the first night of the Democratic National Convention, Democrats on Tuesday are bringing out another lineup of familiar faces to support Kamala Harris’ presidential campaign.

Former President Barack Obama and Michelle Obama, along with second gentleman Doug Emhoff, are headlining night two of the convention.

The involvement of high-profile figures like the Obamas highlights the party’s dedication to mobilize a broad base of voters for the upcoming election.

In his Tuesday speech, Obama is expected to highlight why Kamala Harris and Tim Walz are well-suited to lead the country and address the challenges Democrats face in the coming 10 weeks.

The pivot toward the presidential campaign’s final 76 days follows an opening night that was designed to give a graceful exit to the incumbent president, who was greeted with a hero’s welcome for stepping aside for Harris.

Biden’s appearance will likely be remembered for the emotional introduction by his daughter Ashley, and his fiery defense of his accomplishments as he echoed his 2020 warning about the risks to democracy if former president Donald Trump wins a second term. Biden was frequently interrupted with chants of “Thank you, Joe.”

With Biden’s public endorsement secured, the convention shifts to targeting the handful of key swing states Harris and running mate Gov. Tim Walz of Minnesota will need in November to retain the White House for Democrats.

The Harris campaign said it will spotlight “trusted messengers” from these states over the convention’s three remaining days. They include Sen. Catherine Cortez Masto of Nevada; Gov. Gretchen Whitmer, Sen. Gary Peters and Rep. Elissa Slotkin of Michigan; Sen. Bob Casey of Pennsylvania; and Sen. Tammy Baldwin of Wisconsin. From Arizona, Sen. Mark Kelly will speak along with John Giles, the Republican mayor of Mesa.

Harris also announced Tuesday an array of prominent Republicans set to speak at the convention, including former U.S. Rep. Adam Kinzinger of Illinois, former Georgia Lieutenant Gov. Geoff Duncan and former Trump White House staffers Olivia Troye and Stephanie Grisham. All are now critics of Trump.

Trump, meanwhile, is visiting battleground states during the convention. He went to Howell, Michigan, on Tuesday and stood aside sheriff’s deputies as he labeled Harris the “ringleader” of a “Marxist attack on law enforcement” across the country.
