As we wait for Kamala Harris to address her staff at the campaign HQ in Delaware, we can see via the live cameras that last-minute preparations are hastily still under way.

Hinting at the lack of notice given by Joe Biden when he pulled out of the race this weekend, aides appear to be sticking "Kamala" posters to the wall behind the lectern.

Several staffers appear to be adding more tape to the posters to ensure they don't fall down during Harris's speech.

We are expecting Harris to speak soon, so stick with us.

Kamala Harris has been greeted by her campaign team with a round of applause as she arrived at the headquarters in Wilmington, Delaware.

She had boarded the plane to fly to meet her team directly after her first remarks on the White House South Lawn following Joe Biden's endorsement earlier today.

More than $81 million has been donated to Kamala Harris's campaign in the 24 hours since Joe Biden announced his decision to pull out of the presidential race, her campaign says.

A statement from Team Harris says that it's the largest amount raised in a 24-hour period for a presidential candidate in any US election, with more than 888,000 donors making contributions of less than $200 in the day after Biden stepped aside.

“Grassroots supporters are energized and excited to support her as the Democratic nominee,” ActBlue, the progressive donation platform said on X.

Donors who had pulled back their funding over concerns about Biden’s age say they now intend to resume their support for the party.

I have been exploring the reaction to Joe Biden’s withdrawal from the US presidential race, and the prospects for a potential Kamala Harris campaign.

Most senior Democrat Party figures have already thrown their support behind the vice president.

I have also been examining how Donald Trump and the Republican party might recalibrate their own campaign if Harris were to formally win her party’s nomination.

As we've been reporting, before he quit the race, Joe Biden had nearly $96m (£74m) in the Biden-Harris campaign account at the end of June, according to the Federal Election Commission (FEC).

The campaign has been renamed to “Harris for President”, officially naming Vice-President Kamala Harris as its candidate for president. That means she can continue using the funds the Biden campaign has already raised.

But there could be questions over the money now that Biden isn't on the ticket.

Citing campaign finance regulation, FEC chairman and Republican appointee Sean Cooksey says if a candidate is no longer on the ticket for the general election, contributions may need to be returned or refunded - but he doesn't address Harris being on the campaign account already.

Harris can use Biden's campaign as they shared a campaign committee but according to the Campaign Legal Center, if the new ticket didn't not include Harris, different rules would apply.

An advert posted by the Republican party shortly after, external President Biden dropped out of the race claims Vice-President Kamala Harris “was put in charge of stopping illegal immigration” as the administration’s “border tzar”.

In 2021, she was asked by Biden to look into the “root causes”, external of migration into the US, but she has not been overseeing the day-to-day running of border security – this is the job of Alejandro Mayorkas, the secretary of homeland security.

The term “border tzar” is of the Republican’s own invention - it was never a title given to this role by Biden or anyone else in the administration.

The Republican advert also claims there has been “a record number of illegal immigrants - 10 million and counting - flooding over the border” since 2021.

This figure is correct.

Since Biden took office, the US Customs and Border Protection, external agency says there have been almost 10.1 million encounters of people crossing the southern border by enforcement officers.

This is a significant overall increase on the four years under Donald Trump, and is also the highest figure recorded under any US administration.

With Biden off the ballot, how much will inflation matter?published at 20:48 British Summer Time 22 July

It’s been one of President Joe Biden’s biggest problems: the economy.

Voters have told pollsters repeatedly that they were angry about inflation, and after the jump in prices, did not trust Biden on economic issues.

Does the problem go away with another candidate on the ballot?

It’s hard to know.

There were already some signs that the economy’s power to sway votes was limited. For one thing, people’s degree of dissatisfaction often depended on what party they belonged to in the first place.

In the last two years, the price increases have also significantly subsided, removing some of the urgency from the question.

Still, if Kamala Harris is the Democratic nominee, there is no doubt Republicans will try to saddle her with Biden’s record.

“Don’t get it twisted - Joe and Kamala share the same record. Border disaster, collapsing economy and so much more are all on her hands as well,” Trump ally Kaelan Dorr wrote on social media, external.

The Trump campaign is also likely to point to her family background - her father was a professor of economics at Stanford University known for his criticism of some traditional economic theories - to sow doubts on this issue.

We've had an update from the White House doctor on President Biden's health, after testing positive for Covid last week.

Kevin O'Connor says that Biden's symptoms have "almost resolved completely", and his pulse, blood pressure, respiratory rate and temperature "remain absolutely normal".

He adds that Biden continues to perform all of his presidential duties.

Biden's lungs remain clear and his oxygen saturation "continues to be excellent on room air", the doctor adds.

Kamala Harris has boarded the vice-president's plane, known as Air Force Two, to travel to Wilmington, which had previously been the headquarters of the Biden re-election campaign.

In a post on X earlier today, she said she was on her way to greet the campaign staff.

"It's the first full day of our campaign, so I'm heading up to Wilmington, DE later to say 'hello' to our staff in HQ.

"One day down. 105 to go. Together, we're going to win this."

Supporters of Kamala Harris believe she can beat Donald Trump on his policy proposals especially when it comes to abortion rights.

President Biden made it centre stage of his election bid but many advocates had doubts he was passionate about it, having once said as a practicing Catholic he was "not big on abortion".

Contrast that with Harris, who became the first VP to visit a clinic run by Planned Parenthood in March. She also went on a nationwide tour last year to promote reproductive rights. She’s also criticised Republican efforts to block IVF treatments.

Donald Trump has boasted about installing the Supreme Court justices who ultimately overturned Roe V Wade. And in the two years since the constitutional right was removed, Republicans have struggled to articulate a very clear position on it.

Following a long back and forth, Trump said recently he wanted abortion policy to be left to the states to decide.

Light of polls and state-wide ballot initiatives have consistently shown most Americans in favour of abortion rights - proving it’ll be a big issue for voters in November.

The Democratic leader of the House of Representatives Hakeem Jeffries says he will meet Vice-President Kamala Harris alongside Democratic Senate leader Chuck Schumer today.

Jeffries and Schumer are two of the most senior Democrats who have not yet endorsed Harris since Biden dropped out of the race on Sunday.

Speaking to reporters, Jeffries says Harris has "excited the community, she's excited the House Democratic Caucus and is exciting the country", and he will have more to say about the "path forward" as soon as the meeting is over.

Just before his vice-presidential pick JD Vance went on stage in Ohio, Donald Trump hit out against Joe Biden and Kamala Harris on social media.

"Joe Biden will go down as the Worst President in the history of the United States," Trump posted on his Truth Social, external platform.

"KAMALA, OUR HORRIBLE & INCOMPETENT BORDER CZAR, WILL BE WORSE!" he added, referring to Harris's work on immigration for the White House.

During his campaign stop in Ohio, JD Vance recalled the moment Donald Trump asked him to be his vice-presidential running mate.

Vance says Trump asked to speak with his seven-year-old son, whom the former president could hear in the background.

Vance has ended his remarks, but before he left the podium he mentioned the recent attempted assassination of Trump, saying he was upset by the close call on Trump's life.

"He cares about human beings, he is not the caricature of the lie that the media has told that he is," Vance says.

You can follow our separate live page on the US Secret Service director Kimberly Cheatle's grilling by a bipartisan House Committee over the assassination attempt here.

"I don't like Biden and I don't like his policies," Vance says,

He references Biden's stepping aside as a presidential candidate: "What is going on in this country is disgraceful."

He claims that the decision for Biden to pull out of the 2024 election was made in a "smoke-filled room" of Democratic Party elites rather than voters.

"That is the threat to democracy, not the Republican Party," he says. It's a direct response to a talking point often deployed by Democratic politicians, who warn that a second Trump presidency would be a threat to democracy due to his actions on 6 January 2021.

He then accuses Harris, Democratic senators and the media of lying about Biden being up for the job of president, when "everyone who saw Biden knew he wasn't capable of doing the job", and that they said nothing to the public "until he became political deadweight".

"That is an insult to voters," Vance says.

Vance is now talking about prioritising American energy, repeating the common Republican refrain "Drill baby drill" - a reference to support for oil and gas drilling. The crowd responds to the line with loud applause.

The vast majority of Republicans support the continuation of fossil fuel use in the US, while many Democrats want to see fossil fuel use decreased or phased out.

Sticking to economic talking points, Vance then goes on to call for drugs such as aspirin to be manufactured in the United States instead of China.

Switching to Biden's decision to step aside, Vance then hits out at Vice-President Harris - endorsed by Biden to take on Trump and Vance in November - and says she talks about US history with condemnation rather than appreciation.

"If you want to lead this country, you should feel that gratitude, and I never hear that from her," he says.

Vance then casts doubt on who is calling the shots in the White House with Biden in power and, hyping up the crowd, asks the crowd, "Are we ready to re-elect Trump?"

Continuing to speak about the former president, Vance says that while researching his speech for the recent Republican National Convention, he found that a lot of "stupid mistakes" in American politics in recent decades had been criticised by Trump at the time, citing the 1990s North American Free Trade Agreement (Nafta) as an example.

Vance says this sent "good manufacturing jobs to Mexico" and "allowed them to build their middle class off the backs of Americans".

He also cites the 2003 war in Iraq, when the US declared war against Saddam Hussein. Vance says he supported it at the time, but that now he believes he was wrong and that Trump's later criticism of the move was "right". Trump has previously said he was always against the US invasion of Iraq, but he is on record as saying otherwise.

Vance is now telling the story of how Donald Trump selected him as his vice-presidential running mate.

Vance says he thought maybe Trump would select him when he went to the Republican convention in Milwaukee last week.

When the former president called and formally asked him, Vance says he said, "Yeah, of course".

He says his seven-year-old son was in the background making noise during the call, and Trump asked to speak to the young boy.

Vance tells the crowd that moment shows that Trump cares about families.

JD Vance is up at the lectern, greeting the crowd with a wide grin.

"It's good to be back home," he says - Vance is speaking from his hometown of Middletown, Ohio.

He offers his thanks to a handful of Republican leaders, points out a couple of family members in the crowd and begins reminiscing about his childhood in Middletown, passionately declaring: "I will never forget where I came from."

Turning towards the election in November, Vance says neighbouring state Michigan will be a key battleground state.

"We have to work hard for every single vote," he says.
