The event will run for 90 minutes without commercial interruption. It would've been the third debate of the 2020 presidential election, had the second taken place. After Trump, the Republican candidate, was diagnosed with COVID-19, the Commission on Presidential Debates decided the second debate should be held virtually.

The president announced he would not participate in a virtual event, and then Biden agreed to participate in a town hall at the Constitution Center in Old City with ABC News on Oct. 16, the same night the debate would have taken place. The debate commission eventually canceled the debate, and Trump also participated in his own town hall hosted by NBC News.

On Monday, the Commission on Presidential Debates also announced it would mute both candidates' microphones during portions of Thursday's debate. Both Trump and Biden's microphones will be muted for two minutes each at the start of each topic segment, when each candidate is supposed to give the other uninterrupted time to talk. The Commission said they decided to mute the microphones after the Cleveland debate "to ensure a more orderly discussion of the rules."

Where is the last debate taking place?

Belmont University in Nashville will host the debate at the college's Curb Event Center. The university said it would adopt the coronavirus health and safety guidelines used for the presidential debate at Case Western Reserve University in Cleveland. Belmont University leaders partnered with Nashville-based healthcare group HCA Healthcare to help implement the Cleveland event's coronavirus mitigation strategies.

On Oct. 12, the president's physician, Dr. Sean P. Conley, said Trump had tested negative for the coronavirus and was no longer a threat to spread the disease. Trump has since resumed holding campaign events.

What topics will Trump and Biden debate?

On Friday, the Commission on Presidential Debates said Kristen Welker had selected the following six topics for the candidates to discuss: fighting COVID-19, American families, race in America, climate change, national security and leadership.

Like the first presidential debate's format, this event will be divided into six, 15-minute segments to discuss each topic. The exact questions are picked by the debate moderator and not revealed beforehand.

Chris Wallace, who moderated the first debate, chose the following topics: the Supreme Court, Trump and Biden records, COVID-19, the economy, race and violence in our cities, and the integrity of the election.

During Thursday's town hall, Trump answered questions from voters and moderator Savannah Guthrie of NBC News about the coronavirus, economy, conspiracy theory group QAnon, and white supremacists. The president denied he had failed to denounce white supremacists in the first debate, despite that when he was pressed to do so, he told the hate group the Proud Boys to "stand back and stand by" during the first debate.

He also defended retweeting a conspiracy theory that Osama bin Laden had not been killed by Navy SEALS, leading Gutherie to say the president's social media activity should be held to higher standard than "someone's crazy uncle." Watch the exchange below:

At Biden's town hall in Philadelphia, the former vice president answered questions from voters and host George Stephanopoulos about the U.S. Supreme Court, his 1986 and 1994 crime bills, transgender rights, foreign policy, and fracking. Biden once again said he would not ban fracking.

In one of the most notable moments of the night, Cedric Humphrey, of Harrisburg, asked Biden about when earlier in the campaign the Democratic candidate said, "If you have a problem figuring out whether you're for me or Trump, then you ain't black."

Humphrey asked Biden. "Besides 'You ain't black,' what do you have to say to young black voters who see voting for you as ... further participation in a system that continues to not protect them?" 

Biden responded with a quote from John Lewis about voter participation and described policies he would have as president that  would help the Black community and makes him "worthy" of their vote. Watch video of the exchange below.
