In Milwaukee, we're about to hear from Donald Trump and then Kamala Harris will start her own rally in the Wisconsin city not long after.

The state is one of seven swing states that will be crucial in determining the outcome of the presidential election.

With a population of 5.9 million, Wisconsin holds 10 of the 538 electoral college votes.

Wisconsin’s mix of cities, small towns and large rural areas has made it one of the most-contested states in 2024.

When Harris appears in the state she tends to accuse Trump of being a threat to democracy and focus on his false election claims. But at Trump rallies, immigration is the big issue and supporters talk about how their candidate - and by extension, his backers - have been treated unfairly.

The yard signs and bumper stickers are all very much on message - piled up in the hallways as we waited a bit earlier today to enter the former president's final rally of the day here in Milwaukee.

The problem of course is that the candidate is struggling to stay on message - his latest outpouring involving the idea that fellow Republican, Liz Cheney - who is supporting Kamala Harris - would not be a "radical war hawk" if she was in a war herself and had guns "trained on her face".

That of course comes on top of his comments earlier in the week about "protecting women" - "whether they like it or not" and after the debacle surrounding a comedian and his "jokes" about Puerto Rico last Sunday.

It's far from clear whether there's any tactics, let alone strategy, behind Trump's interventions - some of which he publicly says his campaign would rather he avoid.

One thing is clear - he rarely tries to clean up any missteps after the fact - preferring in fact to double down. We are holding our breath for tonight's instalment.

The pre-program at tonight's Donald Trump rally in Milwaukee is a bit of a mystery tour since the campaign hasn't published a list of the warm-up speakers.

So imagine my surprise when Scott Walker walked on stage.

Who is he? I hear you ask.

Well, he is in fact a former Republican governor of Wisconsin, but perhaps more significantly, he was the man in 2015 who attracted all the smart money to be the next president of these United States.

The hype around him was huge. He had the backing of the powerful Koch brothers.

But just two months after he announced he was entering the race for the Republican nomination - he was gone - a footnote to presidential history.

Politics can be a brutal business.

You sometimes forget, being on the election beat and on the road the whole time, that not everyone is obsessed with politics and the outcome of this race.

When we arrived at our hotel in Milwaukee last night, we were greeted by dozens - no hundreds - of grown men and women dressed up in "My Little Pony" costumes - enjoying what turns out to be the tenth year of their convention, external.

You add to that the fact that they were also having a Halloween party, and it turned into a very confusing evening indeed.

Regularly, as we make our way to these various venues, people stop us and ask us what's happening, seemingly, some would say, gloriously oblivious of the fact that a former or prospective president is in their town, pitching for their votes.

All of which is a sobering reminder, that life goes on even in these frenetic and febrile times - politics really isn't everything.

We now have a decision in a case we wrote about earlier today.

Pennsylvania's Supreme Court has ruled that mail-in ballots that are not dated correctly should not be counted in the upcoming presidential election.

Republicans are hailing the ruling as a "big win for election integrity."

This ruling is separate from the US Supreme Court's decision on provisional ballots.

Pennsylvania law requires voters to handwrite the date on which they filled out their ballot, but a state appeals court on Wednesday decided that the mandate was unconstitutional in a case involving a few dozen ballots cast in a special election in September.

That ruling prompted both Republicans and Democrats to ask the Pennsylvania Supreme Court to clarify how the decision would impact ballot counting in the presidential election. Pennsylvania will begin tallying mail-in ballots after the polls close on Tuesday.

Republican National Convention Chairman Michael Whatley called the rule "an important ballot safeguard."

Democrats, meanwhile, have argued that the mandate "serves no purpose" because a ballot's timeliness is determined by when it is scanned by election officials, not when it is filled out.

Harris once again makes her pitch to young voters - some of whom will be casting a ballot for the first time on 5 November - saying "I love Gen Z, I really do".

She adds that young people are “rightly impatient for change” on gun violence and the climate crisis.

In closing, Harris asks her supporters to knock on doors, text their friends and tell their families to go out and vote.

"Your vote is your voice, and your voice is your power,” Harris says.

Harris’s remarks lasted nearly 30 minutes - much shorter than Trump’s earlier rally in Warren, Michigan.

She will appear on stage once again tonight in Milwaukee, where she is scheduled to speak alongside rapper Cardi B. Trump will also be holding his own rally in Milwaukee tonight.

At a rally in Green Bay, Wisconsin, Kamala Harris is attempting to draw a contrast between herself and her opponent - Donald Trump - billing herself as part of “a generation of new leadership in America".

She leans on her experience as a prosecutor and former attorney general of California, as she has numerous times during the campaign, saying that she is someone who would fight predators, criminals and drug traffickers.

“If you give me the chance to fight on your behalf as president, there is nothing in the world that will stand in my way,” Harris says.

Trump, she says, is not someone who is “thinking about how to make your life better,” repeating her assertion that he is “unstable” and “obsessed with revenge”.

Harris then outlines some of her key priorities if she were elected president, including covering the cost of healthcare for seniors under Medicare, lowering the cost of childcare and cutting taxes for small businesses.

She goes on to say that Trump’s economic plan will cost the average American family thousands of additional dollars per year.

• For context: Harris has repeatedly said this and it's a reference to Trump’s plan to increase tariffs - or taxes - on foreign goods entering the US if he becomes president. Many economists believe tariffs increase prices for consumers, but it’s not guaranteed that the impact would be as big as Harris claims. BBC Verify looked into these claims.

The Supreme Court’s decision affects provisional votes in Pennsylvania, a key swing state worth a whopping 19 points in the crucial electoral college system that decides the next president.

In many parts of Pennsylvania, voters are notified if their mail-in votes are not counted due to being faulty. Such postal votes can be ruled defective if they are not signed or dated by the voter, or do not come enclosed in the provided secrecy envelope.

Voters who are informed that their mail-in ballots have an error are then able to request a new ballot or go to a polling station and vote in person.

These ballots are called "provisional", and they typically do not count until questions about a voter's eligibility are resolved.

According to the Associated Press, of the 1.6m mail-in votes already cast in Pennsylvania, 9,000 ballots have arrived without a signature, date or security envelope.

Republicans wanted to blocka 23 October ruling by Pennsylvania’s high court that allowed voters to submit in-person provisional ballots if their postal ballots had been ruled defective.

While the US Supreme Court on Friday rejected the Republicans' appeal, it may not be the end of the matter, which could ultimately return to the justices.

It is unclear how many provisional ballots will now be counted, after the Supreme Court's ruling.

The US Supreme Court has cleared the way for Pennsylvania to count thousands of ballots that Republicans had wanted to be set aside.

The Pennsylvania Supreme Court had ruled that voters who returned postal ballots without the required secrecy envelope - which could invalidate their vote - could submit a provisional ballot instead on election day.

Republicans had asked the US Supreme Court to freeze that decision, arguing it went against the state's election code. Friday's dismissal of their emergency appeal is a legal blow in a potentially pivotal swing state.

As we've been reporting, Donald Trump is visiting Dearborn, Michigan - an Arab-American majority city in a swing state.

Voters in this state - and city - appear to be split, in large part due to anger at the Democrats' Middle East policy.

On the streets today, chants of "USA" and "Free Palestine" could be heard among the assembled crowd.

Democrats are asking the Pennsylvania Supreme Court to rule on whether mail-in ballots that are not dated correctly should be thrown out.

The state requires voters to handwrite the date on which they filled out their ballot.

But a Pennsylvania appeals court on Wednesday ruled that the mandate was unconstitutional in a case involving a few dozen ballots cast in a special state election in September.

It was unclear how the ruling would affect how mail-in ballots are counted for the presidential election and in a filing on Friday the Democratic National Committee and local Democrats asked the court to make a decision on whether the mandate applies before election day.

Democrats want the rule removed, arguing that the date on the ballot-return envelope “serves no purpose” because a ballot’s timeliness is determined by when it is scanned by election officials.

Republicans, on the other hand, have asked the Pennsylvania Supreme Court to enforce the mandate in time for election day.

In a court filing on Thursday, they argued that the appeals court ruling violates a previous decision that no “substantial alteration to existing laws and procedures” be made before the ongoing election.

They have asked for a stay on the lower court’s ruling while all appeals on the case are heard.

Many believe Muslim votes could be the difference between the winner and loser in the battleground state of Michigan.

Kamala Harris has struggled to win the wholehearted support of these traditionally Democratic voters, who are angry with the Biden administration's position on the war in Gaza. Donald Trump has tried to win over these voters by making a trip to Dearborn, Michigan - a city with an Arab-American majority.

This may add to Harris’s challenge in a dead-heat race, but a few Muslim leaders working on the ground for Democrats in Michigan also warn that it would be a mistake to treat the entire community as a monolith.

Mohammad Hassan, an elected member of the fully Muslim city council in Hamtramck, estimates that 80% of the 25,000-strong Bangladeshi Muslim community is voting for Harris while the remaining 20% could go for Trump.

“But Yemeni Muslims in the same city may go 50-50 between Trump and Harris,” says Hassan, who has been active in door-knocking operations in the state for nearly two decades.

He says the anger within the Arab-Muslim community over the Gaza war is real but, unlike the Bangladeshi community, they do not turn up to vote in big numbers.

There are also some voters within the Arab community who regard Harris as the candidate with the “temperament to find a solution” in the conflict, according to another Muslim leader.

“They are not naïve people. They understand what’s at stake," says Anam Miah, a former council member.

Trump called people of Yemen origin people of “terrorist background” during a speech in Pennsylvania, he says.

"So when he tries to get their endorsement in Michigan, he is basically saying - I like you but your people are terrorists," says Miah.

A bit before Donald Trump took the stage in Warren, Michigan, he took to Truth Social to address recent criticism levelled against him about comments he made about Liz Cheney.

In those comments, made during a rally last night, the former president suggested one of his most vocal Republican critics would not be a "radical war hawk" if she was in a war herself and had guns "trained on her face".

On Truth Social, he seemed to double-down on those remarks, saying: "It's easy for her to talk, sitting far from where the death scenes take place, but put a gun in her hand, and let her go fight, and she'll say, 'No thanks!'".

Earlier today, Arizona's top prosecutor told local US news that she was investigating whether the Republican presidential nominee violated state law by making a "death threat" against Cheney during the Thursday night event in Glendale.

"I have already asked my criminal division chief to start looking at that statement, analysing it for whether it qualifies as a death threat under Arizona's laws," Attorney General Mayes, a first-term Democrat, told the US news outlet 12News.

Trump is now bringing up the latest US jobs report that was released today.

The figures - 12,000 new jobs for the month and an unemployment rate of 4.1% - showed that growth has slowed sharply in October, partly due to two back-to-back hurricanes and labour strikes.

He calls the report "bad news", blaming Kamala Harris and Joe Biden for driving the US economy "off of a cliff".

Trump tells his supporters that if Harris wins, the US may never recover.

"This is not good news for them," Trump notes, adding later that the Biden administration has "wiped out" thousands of manufacturing jobs under their tenure - a claim that has been disputed by experts, external.

He then takes aim at the "fake news people" for not reporting these figures.

Trump's messaging on this issue is particularly targeted to Michigan voters, who have expressed that the economy and jobs are top of mind as they head to the polls.

Donald Trump is now speaking at a rally in Warren, Michigan.

"We're not going to have this too much longer, you know, we're winding down," he tells supporters as election day draws near. "Hopefully we'll be going to the next phase, which is to turn our country around."

Trump promises more rallies to his supporters if he is elected as president. "It's been the experience of a lifetime for a lot of us," Trump says.

He then asks a question he has posed several times in his recent rallies: "Are you better off now than you were four years ago?"

"I don't think so," Trump responds.

He adds that he is coming with "a message of hope for all Americans," reiterating his promises to "end inflation, stop the invasion of criminals pouring into our country, and I will bring back the American dream."

Trump emphasises his get-out-the-vote message, telling supporters not to believe the polls. "Nothing matters except what happens on Tuesday," he says.

We are now just four days out from the 2024 US presidential election, and both candidates have been busy hitting the ground running in key battleground states to make their final arguments before voters head to the polls.

If you are just joining us, here's the latest so far:

• Donald Trump is under fire for comments he made on Thursday about former Republican House representative Liz Cheney, saying that she is "a radical war hawk" who would be opposed to war if she had guns "trained on her face"
• Cheney called Trump "petty, vindictive," and "cruel", while Kamala Harris said Trump's comments should be "disqualifying" him from running for office
• US jobs growth has slowed sharply in October, according to new numbers released today - these figures are closely watched ahead of an election, as they give an indication about the strength of the US economy
• Over 66 million Americans have cast an early ballot as of yesterday
• Rival running mates Tim Walz and JD Vance are holding duelling campaign events in the battleground state of Michigan. Walz addressed undecided voters in his speech, while Vance painted Democrats as "people who hate their fellow citizens"
• US intelligence has called out Russia for attempting to interfere with the upcoming election by spreading misinformation online, including a video of a Haitian man who falsely claims to have voted "multiple times" in Georgia

Up ahead, we still have:

• Harris in Wisconsin, a closely contested state, where she is making several stops before appearing alongside rapper Cardi B at a rally in Milwaukee at 22:00 EDT (03:00 GMT)
• Trump, meanwhile, is paying a visit to Dearborn, Michigan, a city with a large Arab-American population, before making his way to Wisconsin, where he will hold his own rally in Milwaukee at 20:00 EDT (01:00 GMT)

Elon Musk's bid to move a lawsuit over his $1m (£770,000) election cash giveaways to a federal court has been denied, sending it back to the state court.

The Donald Trump supporter has, through his political group America PAC, been offering cash prizes to registered voters in swing states who sign a petition - something US officials suggest may break electoral law. Musk denies this.

Earlier this week, Philadelphia District Attorney Lawrence Krasner sued Musk over the giveaways, saying the billionaire "must be stopped, immediately, before the upcoming presidential election".

Musk had requested the lawsuit move to a federal court, arguing it raised questions that involved federal law. Krasner says it was an attempt to "run the clock until election day".

It's not yet clear how this decision affects Musk's daily giveaways, or when the lawsuit will be heard.

We can now bring you a some more details from Donald Trump's stopover in Dearborn, Michigan.

At a meeting with Arab Americans and other voters, the former president began to address the conflict in the Middle East, saying there were people in the region and the US who were "not doing their job", Reuters reports.

The former president also specifically addressed the conflict between Israel and Lebanon, saying first that he knew "many people form Lebanon" and then added that "we have to get this whole thing over with".

When reporters travelling with Trump later pressed him for specifics on his plan to solve the ongoing war in the Middle East, however, he did not offer details.

When he was asked by the New York Times whether he had spoken with Prime Minister Benjamin Netanyahu about a plan to end the regional conflicts, he replied, “I always talk about things like that".

There’s a phrase you hear often in this country: all politics is local.

So when Hurricane Helene swept through the battleground state of North Carolina, with a little over a month to go until the US presidential election, the question remains: will it have an impact?

The devastation in Asheville is astounding. Entire areas by the river are all but flattened. Clean drinking water hasn’t yet been restored, and some voters tell us that those who have lost homes and livelihoods might not be focused on heading to the ballot box.

Then there’s the issue of how people feel about the disaster response. In the wake of the storm, former President Donald Trump spread misinformation that the Biden administration had redirected US Federal Emergency Management Agency (Fema) relief funds to undocumented migrants.

Although this was untrue, in politics, perception can quickly become reality. On top of these political hurdles, there are practical ones, too.

Some voting infrastructure has been washed away, and Yancey County has erected a tent to allow people to cast their votes.

But up here in the Blue Ridge Mountains, people are resilient.

“These people will crawl over trees and through mud to turn out and vote,” Ruth Smith, a Republican candidate running for election to the North Carolina House of Representatives for District 115, tells us.

Both Harris and Trump will be hoping that’s true — in a battleground state where every vote counts.

I’ve been speaking to Dr Hassan Abdel Salam, who just gave a Friday sermon to “hundreds” of Muslim voters here in Dearborn, Michigan.

As we've been reporting, Donald Trump is visiting the city here today.

Dr Salam says his number one message to those in the hall was to “punish the vice-president” for the Democrats’ support for Israel.

(As we mentioned a bit earlier, there are some Arab American voters facing backlash over their decision to vote for Harris.)

He believes that there are enough Muslim voters who are angry at the ongoing conflict in the Middle East to deny Kamala Harris a win in the swing state of Michigan.

He argues that helping cause Harris to lose the election would gain his community leverage over both Democrat and Republican policy by showing they have “power”.

He tells me he's decided to vote for Jill Stein, the Green Party candidate.
