Davion Hampton from Florida wants to vote in this US election, but can't.

Though former prisoners like Davion had their voting rights restored in 2018, when Florida voters passed a state amendment, Republican lawmakers decided that a jail sentence was only complete when all prison fines and fees had been paid.

Eight years after leaving prison for a drugs offence, Davion still owes more than $50,000.

While state officials feel it's part of his punishment, campaigners believe thousands like Davion are being denied a say in what could be a pivotal state in the US election.

Twitter has said, external it will place warning labels on any tweets that claim an unverified win for any candidate in the presidential election.

Twitter users “may not claim an election win before it is authoritatively called”, the company said.

“To determine the results of an election in the US, we require either an announcement from state election officials, or a public projection from at least two authoritative, national news outlets that make independent election calls,” it added.

On Sunday, President Trump denied a report that he would declare victory on Tuesday if it looks like he's “ahead” in key battleground states, external. However, he did bemoan the counting of votes after election day, though it is standard procedure in the US.

If Trump were to declare victory prematurely on Twitter - his favoured means of communication online - he may fall foul of the company’s policy. But it wouldn’t be the first time Twitter has tagged one of Trump’s tweets as misleading.

In August, Twitter hid a tweet by Trump for containing "misleading claims" that could "dissuade voters" ahead of the election.

While attention has been hyper-focused on the battle for the White House between Donald Trump and Joe Biden, an equally important fight is underway for control of Congress on 3 November.

The Democrats already have control of the House of Representatives, so they are looking to keep hold of it, while also gaining a majority in the Senate.

A Democratic-controlled House and Senate would have the power to obstruct the plans of a second-term President Trump, or push through the agenda of a first-term President Biden.

Will Democrats win the majority in both chambers of Congress - or will Republicans hold the Senate?

Here are five races to watch in the other hugely important election on Tuesday.

At a rally on Sunday, President Trump suggested he will fire the country's top infectious disease expert, Dr Anthony Fauci, after Tuesday’s election. But it's not that straightforward.

Fauci is a career civil service employee who has served as the US government’s top infectious disease expert for six presidents. As such, it would be quite difficult for Trump to fire Fauci the way he has political appointees like Cabinet secretaries and White House staff.

There is a detailed process for terminating members of the civil service that includes notice of cause, and the option to appeal the decision to a review board.

Just because Fauci can’t be removed doesn’t mean the White House hasn’t already taken steps to curtail his influence, however.

As the director noted in a recent interview with the Washington Post, external, his access to the president and other policymakers has been drastically curtailed. His recommendations and suggested guidelines on public health matters will have little effect if no one hears or heeds them.

In addition, last month the president proposed a change to civil service rules that would create a new category of employee, Schedule F, that could be removed by the president at will.

If Fauci or any other long-time government employees who have fallen out of presidential favour were to someday receive such classification, their job situation would become considerably more tenuous.

Our theme for today's coverage is the spread of coronavirus and how it has changed the US election.

But will the pandemic affect how Americans vote?

In the past hour, both candidates have climbed aboard their campaign jets, en route to last-minute rallies on the final day before the election concludes.

Trump took off from Miami airport, heading to rallies in North Carolina, Pennsylvania, Wisconsin and Michigan on Air Force One. He was seen clutching a Make America Great Again hat as he ascended the plane's steps.

Biden, departing from Wilmington, Delaware, is heading to events in Pennsylvania and Ohio. He's travelling with his grandchildren, something he has done frequently in the closing days of his "battle for the soul of the nation".

The presidential race has almost been run, but after election day, patience may be needed.

We may not find out who's won on Tuesday. In fact, it could be days before the result becomes clear.

That’s not unusual by historical standards though, and it's common practice for votes to be counted after election day.

The coronavirus pandemic has complicated matters as well. The increase in mail-in voting is expected to push back the release of full results in many key states.

This is because states start pre-processing and tabulating, or tallying, their votes on different dates. Some states, Pennsylvania and Wisconsin for example, do not begin pre-processing ballots until election day, meaning their results may take longer.

The core message is: be wary of the numbers. A candidate who takes an early lead may end up being overtaken as postal or in-person votes are tallied.

Read our guide on what to look out for on election night for more information about the result.

A more secure fence will be put up around the White House on Monday, according to NBC News and other media. It will be “non-scalable”, which means that no-one can climb it (at least in theory).

The fence will be added to barriers that are already in place, including part of one fence that dates back to the Obama years. An armed intruder managed to climb a White House fence during the time that Obama was in office, and so US Secret Service agents argued that a taller one should be built.

The ongoing efforts to safeguard the president and the White House have been ramped up in recent weeks, as protestors descended upon the area and called for Trump’s removal.

More demonstrators are expected to appear around the White House on election night, especially if it is not clear who won, and the Secret Service agents are preparing for the worst.

White House spokeswoman Kayleigh McEnany has confirmed that Trump will be at the White House tomorrow night.

The announcement, which was made on Fox News, apparently cancels the president's plans to host the event at his Washington DC hotel down the street from the White House. City officials had threatened to shut down his event there if it exceeded the 50-person maximum imposed due to the pandemic.

According to the New York Times, Trump hopes to have around 400 guests in the East Room of the White House, which is not subject to the city's laws.

McEnany has become a top campaign surrogate in recent days, leading to allegations that she is violating a law known as the Hatch Act that bans presidential employees from engaging in political activities.

The Trump International Hotel, which opened in 2016, has become an unofficial clubhouse of the presidency, correspondents say, and is popular among conservatives and federal lobbyists.

Earlier we told you about how Biden was courting the black vote on Sunday, as the NAACP (the oldest civil rights group in the country) held "souls to the polls" rallies to encourage black churchgoers to vote.

Here are some pictures from their event in Tampa, Florida - a key swing state that both campaigns desperately hope to take tomorrow.

The final stop of Donald Trump's re-election campaign will be in Grand Rapids, Michigan.

Naturally, it was chosen with care.

Michigan, like most states the candidates have criss-crossed in recent weeks, could prove key to the result.

In 2016, it went to Trump in a surprise win - and with the smallest margin of any state. Just 10,704 votes separated him from his opponent, Hillary Clinton.

This year, however, polls project a five percent lead for Trump's Democratic rival, Joe Biden.

There's another reason Trump has decided leave Grand Rapids until last - the city was where he held his final rally four years ago, during his first presidential campaign.

More than 94 million votes have already been cast, according to the US Elections Project, external.

This site is run by Michael McDonald, a professor at the University of Florida who specialises in early voting, and tracks the number of votes cast by state and overall.

According to his estimates, California has cast the most votes, 11 million.

Next is Texas, with 9.7 million, followed by the swing state of Florida, with 8.7 million so far.

The number of people who've voted early so far is also already 68% of the total number of people who voted in the election in 2016, putting the US on path to record voter turnout.

How many Americans have voted early so far?

The world through its media

Leading newspapers across Latin America are running front-page stories presenting the US election as an epoch-making event and a battle of polarised political visions.

"The world looks towards the United States," ran a headline by Colombia's El Pais newspaper.

Leading Brazilian daily O Globo struck a similar tone. In dispute, the paper said, are "two opposing visions about the democratic system in the United States".

Brazil's Folha de Sao Paulo agreed the US vote would be history-making. “Democracy of the USA lives its greatest test since 1865," ran its print edition banner headline, alongside serious-faced cartoons of the two contenders.

Chile's leading daily, El Mercurio, also saw the US election presenting “completely antagonistic visions and a polarised country".

Argentina’s La Nacion newspaper called the election a “referendum on the legacy and style of Trump”, in a prominent story from its Washington correspondent.

Mexico's leading daily El Universal wrote of "a fracture" in the country's political system ahead of the election.

In Honduras, the El Heraldo newspaper's headline read: "Hondurans in USA incline their vote towards Biden".

However, Colombia's El Pais saw a potentially close race: "The margins between Biden and Trump are narrow. There is nervousness about the effectiveness of the postal vote and about whether Covid will reduce the number of voters who come out this Tuesday."

At a Black Voices for Trump event in Milwaukee, the BBC met Hannah, who said the president has her vote for the second time:

"I’m a Christian, and so the values that I believe in, I find that the Republican platform reflects that very well - and that’s why I voted for Donald Trump back in 2016.

"Over the course of these past four years I’ve seen him really put those words into action and actually protect religious freedom, and freedom of speech and the right to life, and those are reasons why I’m really excited to support him now in 2020.

"I was a little bit nervous at first in 2016 and 2017 to come out and actually tell people that I voted for the president… but after time I just got tired of keeping that inside. I have got some hostility from people - mostly online. But the people in my friendship groups, my family, they are really just curious. They have got questions as to why I, a black young woman, would be voting and supporting someone who’s been labelled racist, woman-hating in the media.

"I feel that the president has really taken steps to show support for the black community, not only with his criminal justice reforms and his platinum plan that he just introduced, but he really holds our community to high standards. He was all for the protests and the peaceful rallying but when it comes to looting and the destruction of black businesses, I think it was good he stood his ground and reinforced that what is right is right, and wrong is wrong. I personally wasn’t offended - I know that others are."

On the eve of the election, Trump and Biden are making their final pitches to voters in crucial states that could determine the outcome.

These so-called swing states could go either way, making them valuable prizes in the race to win 270 electoral college votes (for more on how the US electoral system works, read this).

This year, analysts have identified Florida, Pennsylvania, Michigan, Wisconsin, North Carolina and Arizona as the top battleground states.

An average of the latest polls collated by RealClearPolitics, external suggests Biden has a clear advantage in Pennsylvania, Michigan, and Wisconsin. In the other three, however, it is too close to call.

• Florida: Biden 1.4+ lead
• Pennsylvania: Biden 4.3+ lead
• Michigan: Biden 5.1+ lead
• Wisconsin: Biden 6.6+ lead
• North Carolina: Biden 0.3+ lead
• Arizona: Biden 1.2+ lead

Democratic challenger Joe Biden has been making a specific bid for black support as the campaigning nears its end.

On Sunday he was in Philadelphia – within the crucial battleground state of Pennsylvania - to take part in a “souls to the polls” event, which is aimed at encouraging black churchgoers to vote.

He specifically referenced how the coronavirus pandemic has impacted on black people.

“Every single day we’re seeing race-based disparities in every aspect of this virus,” Biden said at the drive-in event, calling President Trump’s handling of the pandemic “almost criminal”. He also said the pandemic was a “mass-casualty event in the black community”.

Why has the virus hit some communities harder than others? We explored the issue in this video report below.

Absentee votes. Swing states. The electoral college.

If you follow our coverage, you’ll probably see these and many other examples of election-day jargon this week.

To make sense of it all, we’ve put together a guide to some of the key terms you may come across.

Bellwether state: Places like Ohio and Missouri where voters have proven reliable at choosing the national winner

Exit poll: In-person interviews with voters as they leave their polling locations. Only a small number of voters are interviewed, so the exit poll result can turn out to be different to the official count.

Swing state or battleground state: These states lack a clear party affiliation, meaning they are up for grabs for both Democratic and Republican candidates.

Electoral college: Each state gets a number of electors, roughly in proportion to its population. In most cases, whichever candidate wins a state also wins all that state's electors, who meet later to choose the president and vice-president. Because there are 538 electoral college votes, each candidate needs 270 to win.

Here's a quick video break it down...

Our theme today - beyond the usual election live updates - is Covid-19, and how it's affected Americans.

The US has now suffered more than 9.2 million cases and more than 230,000 deaths.

When the death toll passed 200,000, we spoke to owners and directors of funeral homes across the country, who reflected on how the loss of life has pained the families and communities that they serve.

BBC Radio 5 Live

BBC Radio 5 Live's Anna Foster spent Saturday with Republicans at a Donald Trump rally in Butler, Pennsylvania.

So why's he getting their votes?

"He's honest about everything he's done and he doesn't get enough credit for it," one female supporter said. "People need to wake up, because they don't realise what they're going to vote away if they don't."
