#Barack Obama, Hillary Clinton and Kamala Harris headline DNC night three

The Democratic National Convention on Wednesday will feature speeches by former President Barack Obama, 2016 Democratic nominee Hillary Clinton and vice presidential nominee Sen. Kamala Harris.

The packed night of speeches will stream online beginning at 9 p.m. eastern time. Most remarks won’t be delivered live due to the coronavirus pandemic.

Other prominent Democrats also will endorse the Democratic ticket led by former Vice President Joe Biden, including House Speaker Nancy Pelosi, Massachusetts Sen. Elizabeth Warren and former Arizona Rep. Gabby Giffords.

The night is an opportunity for Harris to try to define her biography and candidacy to Democratic voters. Since her selection last week, Harris has been tightly controlled in media availabilities.

Biden, almost 78, would be the oldest-ever president if he wins, heightening the importance of Harris’ candidacy. She is the first black and Asian-American vice presidential candidate of a major party and would be the first female vice president.

Obama and Clinton, meanwhile, will seek to rev up the base. But they give Republicans an opportunity to heap scorn on familiar targets.

President Trump often attacks his predecessor, telling The Post in an interview last week that Obama and Biden “got caught spying on my campaign” during the FBI’s investigation of Russia’s role in the election.

On Monday, Trump blasted Clinton as “a loser, but not a gracious one.”

Obama’s remarks will follow a widely acclaimed speech on Monday by former first lady Michelle Obama, who emotionally endorsed Biden and denounced Trump as a degrading influence on US society.

“Law & Order: Special Victims Unit” actress Mariska Hargitay will make a cameo on Wednesday.

Silvia Sanchez, an illegal immigrant living in North Carolina, will appear with her daughter Jessica, who has a work permit and protection against deportation from Obama’s 2012 Deferred Action for Childhood Arrivals program.

Parkland, Fla., school shooting survivor Emma Gonzalez also will speak.

Biden, who has kept a low profile ahead of his Thursday convention speech, will appear briefly in a clip about the economy. Biden “listens to, and engages with, union workers around how to build back better a new economy,” a DNC release says.
