More than 50m voters have already cast their ballots
We reported moments ago that the plexiglass barriers between the two candidates' podiums were removed.
Looks like that was because the guidance changed after the debate commission learned both Trump and Biden tested negative for Covid-19.
Dr Anthony Fauci, one of the top health officials involved in the pandemic response, was also consulted about the matter and both campaigns have agreed.

For the first time, candidates’ microphones will be muted to allow each man to answer the moderator’s questions without fear of interruption. Once they have spoken, the candidates will be able to challenge each other in the freestyle manner we saw in the last debate – with both mics on.
You can read more on the presidential debate mute button here.
It remains to be seen whether the new addition achieves the debate organisers' aim of enabling the moderator, NBC News' Kristen Welker, to “maintain order”.
If she does need any last-minute tips, though, she could do worse than listening to these teachers, who have some great advice on how to keep order when chaos is beckoning.
How these teachers would take charge in a presidential debate
Live footage of the debate stage shows the plexiglass barriers meant to separate the candidates being removed.
No explanation as to why has been given by the debate commission and it is so far unclear if they will be replaced..
Similar barriers were used in the vice-presidential debate between Mike Pence and Kamala Harris earlier this month as an added safety measure amid the coronavirus pandemic, and following Donald Trump's positive test for Covid-19.

Hunter Biden, the Democratic presidential candidate's son, has become the topic of a fierce election controversy since Trump's impeachment earlier this year.
While his father was in office, younger Biden had business ties in China and Ukraine, leading Trump to accuse the family of corruption. Biden calls the claims "a smear campaign".
Accusations of influence-peddling are common in Washington DC and Trump's children have also been accused of conflicts of interest in lucrative business deals overseas. They, too, deny wrongdoing.
Claims about Hunter resurfaced recently following a New York Post article about an alleged email in which an adviser from a Ukrainian energy company apparently thanked him for inviting him to meet his father, the then vice-president.
During the first debate, Trump attacked Hunter's previous struggles with drug use. From what we've just heard, it seems Hunter Biden's name will certainly be brought up tonight too.

Tim Murtaugh, spokesperson for the Trump campaign, tells me the president will be bringing up the business dealings of Joe Biden’s son Hunter tonight.
Is that what the American people want to hear, when more than 1,000 died of coronavirus yesterday, I ask? This is about selling access to power and Joe Biden’s corrupt 47 years in public life, he tells me.
Meanwhile, Kate Bedingfield of the Biden campaign is doing US network interviews. She says attempts to smear Hunter Biden by the Trump campaign shows they don’t have an argument about why the president should be re-elected.

'We’re still waiting at home for them to come back'
As the US continues to grapple with the coronavirus - and an increase of cases in most states - 62% of voters say the outbreak will be a very important factor in choosing a presidential candidate to support, according to the Pew Research Center.
So I’ve asked voters what they think of President Trump’s response to the pandemic.
Shane Reilly in Austin, Texas, thinks the president hasn’t been empathetic enough. That’s why he’s changing his vote - and memorializing the victims of the pandemic in Texas.
Shane remembers the Texans who have lost their lives to Covid-19
“I voted conservative and was a registered libertarian for a long time,” Shane told me. “But to see the way that Republicans have handled the pandemic, has made this the first time since 1996 that I'll vote for a Democratic president.”
For Monica Muñoz, who lost her father and grandfather to Covid-19, Trump’s response and comments have been adequate.
"I spend a lot of time reflecting on my family's experience with the virus," she says. "I agree with President Trump that we cannot be afraid of Covid-19. Life does not stop because of risks."
"We know more about the virus now than we did in the past several months. We have a personal responsibility to take necessary precautions to care for ourselves and protect others," she adds. "We have to continuously inform ourselves about the virus. My dad would always say 'Nimodo, la vida sigue' (Oh well, life goes on)."

Clare Allcard, 74, from Andorra asks: How are candidates going to entitle the poor of the country to adequate health care?
The question here is about Medicaid, the government-run health scheme for poor Americans. Some rules for how to dispense Medicaid are made by states, but the federal government doles out funding to help cover most of the costs.
Under President Obama’s Affordable Care Act, dozens of states, including some led by Republicans, expanded Medicaid programmes to cover more people.
Conservatives have long urged for caps on Medicaid spending (which cost $597bn in 2018, external), arguing the federal funding has led states to use the money inefficiently. The Trump administration has been unsuccessful in cutting funding outright, but they have managed to push through other measures, like allowing states to take Medicaid access away from the unemployed, permitting states to nix benefits and cap federal funding (though none have done so yet).
On the flip side, Biden has promised to expand Medicaid coverage, saying state politics shouldn’t get in the way of coverage. Under a President Biden, residents in states that did not expand coverage will be able to apply for a public option insurance plan with no extra costs. Those making below 138% of the poverty line will be automatically enrolled.

An article about Joe Biden's son Hunter and social media giants' response to it may be the subject of a forthcoming congressional hearing.
The New York Post recently published an article detailing the contents of a laptop allegedly dropped off and abandoned by Hunter Biden, which contained videos and emails that incriminated the former vice president's son, and implied that Hunter had brokered a meeting between his father and a Ukrainian energy company representative.
However, the Post's reporting has not been replicated by other outlets and several social media outfits, including Facebook and Twitter, took extraordinary steps to limit the spread of the story, as a part of their disinformation efforts. Twitter initially banned sharing of the story entirely, and Facebook demoted it in its feeds.
Republicans have seen this as a nakedly partisan move, charaterising it as Silicon Valley executives "drunk on power". The Senate Judiciary Committee has just voted to order both Facebook's Mark Zuckerberg and Twitter's Jack Dorsey to testify before Congress about their decisions.

The speed with which officials have pointed the finger at Iran and Russia is a sign that they do not want to be caught out with people questioning the failure to call out interference in a timely manner as happened after 2016. But what is different this time is the highly polarised environment. The partisanship offers a divide which other countries can exploit and has also led to people questioning whether assertions of foreign interference by US officials are politically motivated.
But the real worry remains election day and the risk that other countries may try and mess with the voting infrastructure or sow chaos around the results. In particular, intelligence officials do not know if Russia, which had in place the capability to do this in 2016 but chose not to, might pull the trigger this time.
Our candidates are in Nashville, just a few hours away from one of the biggest set piece events of the campaign. Here's a look at their first moments on the ground as we head into the final debate night.
Trump greets supporters on Nashville arrival
Biden touches down in Nashville for debate
Image source, Getty ImagesFirst Lady Melania Trump is making her first public appearance since being diagnosed with Covid-19 earlier this month.
She had been due to attend a rally in Pennsylvania on Tuesday night, but cancelled at the last minute due to "a lingering cough".
That would have been her first appearance at a Trump campaign event in over a year - if you don't include the Republican National Convention in August (which took place largely at her White House home).

Lanhee Chen, who was policy director for the 2012 Mitt Romney presidential campaign, has been sharing his views with BBC News ahead of the debate tonight.
Asked if Donald Trump is likely to take a different approach in this final head-to-head, he says the president is "not somebody who takes the typical debate prep, or has the traditional playbook.
"So the question is, will the Trump campaign - will the Trump team - be able to impose on President Trump to change elements that did not work for him at the last debate, and to ensure that he's addressing issues that undecided voters at this point are still interested in hearing about?"

The president’s chief of staff Mark Meadow is here at the debate venue. I ask him what we can expect from the president tonight, and he tells me “a great debate.”
The Biden motorcade has just arrived at Belmont University for the candidate’s walk through of the debate hall. Trump and Biden both get the chance to have a close-up look at the set-up before the main event.
Here's some of what we know already:
We're watching tonight's debate with voters from battleground states - the places that will ultimately decide the election.
Rom was featured on Tuesday's military veterans panel. He enthusiastically supports the president's re-election.
What are you looking for in the final presidential debate?
I'm looking for a better performance from President Trump this time around. While I think the first presidential debate was a draw, I was expecting a much better performance from Mr Trump. In 2016, I watched all three presidential debates. I thought Mr Trump either held his own or bettered Secretary Clinton. But in the first debate with Biden, Trump didn't do as well as he did in the 2016 debates.
Rom is a member of our US election voter panel. We want to hear from you - what questions do you have for our focus group tonight?
Laura Trevelyan
BBC World News America presenter, Nashville, Tennessee
Tom Perez - who will be in the debate hall tonight - tells me here in Nashville that Joe Biden is ready for President Trump to attack his son Hunter’s business dealings, saying the president just wants to distract attention from his handling of the coronavirus pandemic.
There’s no complacency on the Biden campaign over their national lead in the polls, Mr Perez tells me, they know it's close in the battleground states. It’s all about turnout, says the DNC chair, and he’s encouraged by the forty million Americans who have already voted. Can we expect a less chaotic debate this time, I ask - that’s up to the president comes the reply.
Image source, EPAThe number of overseas US citizens voting in this year’s presidential election could be double that of 2016, the US Vote Foundation has told CBS News.
The foundation, described as a non-profit, non-partisan organisation that helps some of the three million eligible US nationals overseas register and vote, said there had been a rise in voting from abroad in recent years but this year demand was through the roof.
"As so many different crises hit the US, overseas citizens became more and more aware of what was going on and wanted to participate," the foundation’s Susan Dzieduszycka-Suinat said.
The CBS report quoted several overseas voters expressing concern that their ballot may get lost or be discounted in some way. One group, American Citizens Abroad, said it had heard from voters who sent in their ballot requests weeks ago but had still not received confirmation.
Biden: 'Hopefully he'll play by the rules'
Before boarding his flight to Nashville, a masked Joe Biden told reporters at Delaware airport he hoped President Trump would "play by the rules" at the final presidential debate.
He also said: "Hopefully everyone’s been tested", and added: “We’re looking forward to this.”
