Arizona is one of the few remaining states still counting. Here's the latest:

• Democrat Joe Biden is currently leading in the state by almost 30,000 votes, but Trump has been slowly catching up
• Over 95% of ballots have been counted so far, with about 173,000 left to tally, according to the secretary of state. Some 92,000 are in Maricopa county, Arizona's largest
• Biden has performed best in Arizona's cities, while Donald Trump has picked up votes in rural areas
• Trump supporters - some armed with guns - have been gathering at polling stations, demanding every vote be counted
• If Biden hangs on to his lead in Arizona, the state's 11 electoral college votes will put him closer the 270 needed to win the presidency.

Ballots received after 20:00 local time on election night must be kept and counted separately in the pivotal state of Pennsylvania, Supreme Court Justice Samuel Alito has ruled.

Republicans in Pennsylvania have launched a legal challenge calling for late-arriving votes not to be counted, but that has not been accepted.

Instead, the order merely upholds what is already supposed to be happening in the state, as ordered by state officials - to segregate ballots postmarked by 3 November, but received later.

Meanwhile, the counting continues in Pennsylvania. Trump's initial lead there has disappeared as more and more postal ballot are being counted. Biden now leads by almost 22,000 votes in the state - but the race is still too close to project a winner.

We don't know - still - who the next US president will be, but we do know who it won't be - Kanye West.

The 43-year-old rapper has conceded after his self-styled "Birthday Party" collected just 60,000 votes out of an estimated total of 160 million.

When he announced his candidacy in July, West had said that his platform was modelled off Wakanda, the fictional kingdom from the movie Black Panther.

But we may not have seen the last of West's political career. This week, in the wake of his loss, he tweeted "Kanye 2024" this week - signalling another possible bid to come.

As we wait for more results from Nevada, here's a reminder of where things stand:

• With 91% of ballots in the state counted, Joe Biden is currently ahead of Donald Trump by 22,657 votes

• While many rural areas are leaning towards Trump, Biden is winning in the most populous counties
• Earlier, Biden received 2,520 additional votes from Clark County - which includes the city of Las Vegas
• The state has six electoral college votes. Biden has already secured 253 and needs another 17 to clinch the presidency.

Election day in America was three days ago, but the world is still hanging on edge, awaiting final vote counts from crucial states.

From Pennsylvania to Nevada, North Carolina to Georgia, local officials have one plea - please have patience, we're still counting.

All eyes are on Pennsylvania - the state with the largest number of electoral votes of any state yet to announce results.

Joe Biden is ahead, and if he wins in Pennsylvania, he will secure the 270 electoral votes needed to reach the White House.

So far Biden is leading against President Trump - by almost 20,000 popular votes. Biden needs a larger margin to avoid a recount in Pennsylvania.

And with more than 100,000 postal ballots and a large number of provisional ballots still to be counted, that's more than possible, as the majority of these types of votes so far have gone in the Democrat's favour.

As we reported earlier, Joe Biden is planning to address the nation in his home state of Delaware.

Some aides had suggested he might declare victory if more states were projected in his favour, pushing him over the 270 electoral college votes needed to clinch the presidency.

Sources have told CBS News that Biden will speak regardless of the fact that news outlets may not be able to add to his tally, given slower-than-expected vote counting.

CBS cites a Biden aide as saying the former vice-president will not declare victory, but address the electoral situation. Biden leads in the battleground states that are crucial to reaching the White House: Pennsylvania, Nevada, Arizona and Georgia.

The BBC spoke to voters in Philadelphia, in the crucial state of Pennsylvania. Biden supporters were elated as the former vice-president pulled ahead in the count, but some Trump backers were angry.

The message was clear, though: "Philadelphia matters".

As Team Trump prepares to launch a slew of legal challenges to election results, they are expected to name David Bossie, the president's 2016 deputy campaign manager, to lead the fight, NBC and the New York Times report.

Bossie is a seasoned hand at political fighting. Since 2000, he has been president of the lobby group Citizens United. Under his watch, that conservative group secured a landmark Supreme Court ruling granting corporations the same free-speech rights as individuals - and saying these rights could be exercised through political donations.

It had been reported that the president's close circle of advisers were looking for someone to lead their legal challenge. The team were said to want someone like James Baker, a lawyer and senior Republican figure who led the George W Bush team in the 2000 Florida recount.

Bossie is not a lawyer - he dropped out of university to get a head start in politics - but he has all the characteristics the Trump camp seems to appreciate: outspokenness, pugnaciousness and a flare for messaging.

He briefly fell out with the Trump camp last year over a funding scandal , external- but, if reports prove correct - would seem to be back in the fold.

The top election official in Arizona spoke to CNN to explain the latest counts in the closely watched state.

Secretary of State Katie Hobbs said she expected that some ballots would not be counted until the weekend, but that counties were working tirelessly to ensure the quickest, most accurate count.

When asked about President Trump's claims of election fraud, she said there had been "absolutely no irregularities whatsoever".

"Anyone claiming otherwise has no idea what they’re talking about," she told CNN.

Police in Philadelphia evacuated an area close to a ballot counting centre on Friday, after receiving reports of a bomb threat.

According to local media, the police received two calls from the same person about a threat to the city's Fashion District shopping mall. However, a search found no explosives.

The nearby Pennsylvania Convention Center is being used to count ballots from the 3 November election, and the state's result could be key in determining who becomes president.

Donald Trump is angry and disappointed that few allies are coming out in his support on TV or in the streets, sources close to the president have told CBS News.

They say he has been watching a lot of TV, making calls, and dividing his time on Friday between the Oval Office and the residence.

While the Trump campaign is highlighting its legal fight, there is no clear strategy. Some aides recognise that all this should have been thought out months ago, but nobody wanted to have this conversation with the president.

As for next steps in litigation, unless something significant is uncovered in another big state, it all comes down to Pennsylvania. If the margin is close enough, a successful Supreme Court challenge could help Trump.

If the margin of victory is big enough for Biden, the Pennsylvania case will not matter. This is what his legal team reportedly is focusing their efforts on right now.

At Black Lives Matter plaza outside the White House, the mood is festive as Biden supporters are gathering, awaiting what they hope will be the announcement that he’s won the presidency.

Bruce Springsteen’s song Born in the USA is blaring out from speakers.

Demonstrator Don Folden says the country is divided and dysfunctional.

"You have families who can’t talk to each other. I want Biden to unify us. And he won’t need on-the-job training. Right now America is the laughing stock of the world and we need someone to clean up."

Folden is sitting by a sign saying: "Stop Hating Each Other Because You Disagree".

Three young women from Pennsylvania are nervously awaiting the result from their state.

Landers Mayer, Maren Burling and Megan Ganning are feeling increasingly confident that Biden will be the next president.

"I’m excited to see a leader who has a heart, one who values decency," Landers says.

Maren was here in 2016 for the women’s march, and she wants Biden to lead by example.

All three want to see an end to the constant drama in the White House - now almost obscured behind a security fence festooned with anti-Trump slogans.

More results have come in from Georgia, with Biden now ahead by more than 4,200 votes.

The new figures came after more than 7,000 votes were received from Gwinnett County, near Atlanta.

That doesn't leave us much closer to a final result in Georgia, however - thousands of military postal votes could still be counted, as long as they have a postmark of 3 November and arrive by the end of Friday.

And officials have already said they will hold a recount as the race is so tight in the state, which has 16 electoral votes.

As we mentioned earlier (see our entry at 17:44 GMT), Joe Biden may speak to the nation in a prime-time address later on Friday. Sources suggested that was dependent on the race being called in his favour by that time.

The incumbent, Donald Trump, has now taken to Twitter to warn his challenger not to declare victory. "I could make that claim, also," Trump wrote.

In fact, Trump has now twice said he has won the election, even though all votes have not been counted yet, and those that have put Biden in the lead and on course to become the next US president.

Trump's team have launched several legal challenges - seeking even to stop the vote-count.

The final House seat in New Jersey has been won by Jeff Van Drew, a Democratic congressman who switched parties to back President Donald Trump.

Van Drew secured 51.5% of the vote in New Jersey’s 2nd Congressional District, according to the Associated Press news agency, becoming only the second Republican winner in the state in this election.

His opponent, Democrat Amy Kennedy, is married to Patrick Kennedy - a former congressman and nephew of President John F Kennedy.

Van Drew changed parties last year after opposing his party's moves to impeach Trump.

Since election day, Russia's Kremlin-controlled media have increasingly focused on amplifying unsubstantiated allegations of vote-rigging about the US vote.

This line has been promoted on bulletins and talk shows on state TV, as well by pro-Kremlin accounts on Twitter.

Russia's main international news outlet, RT, on Thursday put out several tweets talking about alleged fraud that were flagged by Twitter as misleading.

Much of the allegations appeared to be based on unsubstantiated fraud claims made by Donald Trump and his supporters, particularly about postal voting.

A talk-show host on top state channel Rossiya 1 TV said "the world has not seen any honest democratic elections” in the US.

He went on to speak of “manipulation and falsification”, adding that the perpetrators were not “even an attempting to hide them anymore".

The deadline for military absentee votes to be received by mail in Georgia is the end of Friday (in just a few hours time) and some pundits are now wondering whether the votes of US soldiers and sailors could swing the state.

Biden is currently leading Georgia by only 1,603 votes, according to BBC projections.

Meanwhile, Georgia officials say 8,890 military postal votes are still outstanding. If they are not in soon - and have a postmark of 3 November - they won't be counted.

Military voters have traditionally leaned Republican, according to pollsters. But Trump's clashes with his own military leaders may have turned off some of the rank-and-file.

His attacks on his former aides and generals Jim Matthis and John Kelly, as well as Senator John McCain, could have cost him some military votes. More women and minorities have also been joining the ranks in recent years and they are considered less likely to back a Republican candidate.

Either way, state officials say they will hold a recount, due to the close margin between Biden and Trump. One thing is clear at this stage - Georgia will remain a battleground state for weeks to come.

If you, like us, are staying glued to your screens as the election drama continues, here's a look ahead at what's to come.

We should get more results from Nevada - probably Clark County - by 19:00 EST (00:00GMT).

More results will also come in from Arizona's Maricopa County around 21:00 EST (02:00 GMT). This should include around 100,000 votes, so it will play a role in figuring out which candidate Arizona goes for.

In Georgia, we may also get an update with votes from the Atlanta suburbs. Officials have said there will be a recount in the state given how tight the race is.

Philadelphia officials are planning to update the numbers again in the next few hours - with somewhere around 3,000 votes. All eyes are on Pennsylvania because if Biden wins this one state, he'll win the presidency.

And to further amp things up: Pennsylvania's top election official, Kathy Boockvar, told CNN that a result could come by the end of Friday.

Pro-Biden protesters in Philadelphia have been seen dancing to YMCA by the Village People, a song that was heavily featured at Trump's in-person campaign rallies around the country.

The dance parties broke out as soon as Biden took the lead in the state, leading to speculation he could win the election. If Biden wins Pennsylvania, he wins the White House.

At the White House, Trump aides played the song on their phone, according to our correspondent Tara McKelvey.

"Young man, there's no need to feel down," the song goes.

Encouraging words for both sides tonight.
