Highlights from the first presidential debate held in Cleveland.

President Donald Trump and Democratic nominee for president Joe Biden faced off from a social distance in the first presidential debate of 2020 in Cleveland, just five weeks out from Election Day.

The first presidential debate at Case Western Reserve University and the Cleveland Clinic came on the heels of bombshell reporting from The New York Times on two decades of Trump's tax records, ahead of a contentious Supreme Court confirmation process in the Senate and as the latest ABC News/Washington Post poll shows Biden maintains a 10-point edge among both registered and likely voters.

The coronavirus pandemic's impact on the race was also on display as the two candidates didn't partake in a handshake, customary at the top of such events. The size of the audience was also limited and everyone attending the debate had to undergo COVID-19 testing and follow other public health protocols.

The debate’s moderator, Chris Wallace of "Fox News Sunday," selected six topics for Tuesday with each segment expected to get approximately 15 minutes: Trump's and Biden's records, the Supreme Court, COVID-19, the economy, race and violence in U.S. cities, and the integrity of the election -- the final topic coming as Trump over the weekend wouldn’t commit to a peaceful transfer of power.

Martha Raddatz only journalist to moderate debates with both Biden, Trump

ABC News Chief Global Affairs Correspondent Raddatz said Trump is combative when he debates, saying "dealing with Donald Trump is more like being a lion tamer than a debate moderator. You really have to keep him on time. He'll go after the moderator."

Biden, Raddatz said, often uses humor when he debates.

Debate will be a 'referendum' on Trump’s presidency: Matthew Dowd

ABC News' Chief Political Analyst Matthew Dowd predicted the debate may become the most watched event of the 2020 election cycle with upwards of 70 million viewers expected to tune in before offering his strategy on how each candidate should approach the debate.

"I think Joe Biden has to come across as calm, cool, collected and thoughtful. Present his case about why he wants to be president of the United States, prosecute the case against President Trump about what he's done over the last four years and why he thinks it's been not good for the American public," Dowd said.

Trump, on the other hand, should stay away from a constant attack on Biden, Dowd said. 

"The best thing for Donald Trump is to present the reason why his presidency has been good for the American public. Present it in a way that rehabilitates his image because that's the biggest thing that's holding him back right now. It's not the perception of Joe Biden. It's the perception of Donald Trump," Dowd said. 

Noting about 14% of Americans still identify themselves as undecided voters, Davis asked Dowd who's the real target audience tonight -- and if this debate will change much.

“Right now, Donald Trump comes into this, by all accounts, seven or eight points behind nationally, behind in every key target state in the electoral college, so Donald Trump has to move those voters. Joe Biden has to reassure his voters that are with him already and try to speak to some of those small segment of undecided voters,” he said.

Dowd noted analysts deemed Hillary Clinton the winner of the 2016 debates, although it was Trump who ultimately won the race, but he said this election cycle presents a “huge difference” from 2016 as it’s not a race about choice but a referendum.
