Kamala Harris has been named as Democratic presidential candidate Joe Biden’s running mate.
The California senator of Indian-Jamaican heritage is the first black woman and South Asian American in the role.
Once a rival for the top job, Kamala Harris had long been considered the front-runner for the vice-president.
The former California attorney general has been urging police reform amid nationwide anti-racism protests.
Joe Biden will face President Donald Trump in the election on November 3.
After August 11 announcement, Kamala Harris tweeted that Joe Biden “can unify the American people because he’s spent his life fighting for us. And as president, he’ll build an America that lives up to our ideals”.
“I’m honored to join him as our party’s nominee for Vice President, and do what it takes to make him our Commander-in-Chief.”
On August 12, Joe Biden and Kamala Harris will deliver remarks in Wilmington, Delaware, on “working together to restore the soul of the nation and fight for working families to move the country forward”, the Biden campaign said.
At a White House news conference on August 11, President Donald Trump, a Republican, said he was pleased with Joe Biden’s choice, adding that Kamala Harris did “very, very poorly” in her effort to become the Democratic nominee.
Kamala Harris will take part in a debate with President Trump’s running mate, Vice-President Mike Pence, on October 7 in Salt Lake City, Utah.
In last year’s race to be the Democratic nominee, Kamala Harris showed herself to be a forceful speaker, launching blistering attacks on Donald Trump.
The role of a vice-presidential running mate isn’t always clearly defined.
One of the traditional roles is to go on the offensive in exposing the opposition’s weaknesses, while the presidential nominee focuses on communicating the party’s message.
Constitutionally, the vice-president steps in to the top job should the president die or leave office during his or her term.
Joe Biden will turn 78 in November, meaning should he be elected he will be the oldest US president in history (Ronald Reagan was 77 when he left office).
His age means Joe Biden’s vice-presidential choice may come under extra scrutiny.
Kamala Harris, 55, dropped out of the presidential race in December after failing to make headway in her bid to win the Democratic nomination.
She repeatedly clashed with Joe Biden during the primary election debates, most notably criticizing his praise for the “civil” working relationship he had with former senators who favored racial segregation.
Kamala Harris was born in Oakland, California, to two immigrant parents: an Indian-born mother and Jamaican-born father.
She went on to attend Howard University, one of the nation’s preeminent historically black colleges and universities. She has described her time there as among the most formative experiences of her life.
Kamala Harris says she’s always been comfortable with her identity and simply describes herself as “an American”.
Only two other women have been nominated as vice-presidential candidates for a major party – Sarah Palin by the Republican party in 2008 and Geraldine Ferraro by the Democrats in 1984. Neither were on the winning ticket.
A woman of color has never been appointed to a presidential ticket by either of the two main American political parties. No woman has won the US presidency either.
Joe Biden tweeted that he had “the great honor” to name Kamala Harris as his number two.
He described her as “a fearless fighter for the little guy, and one of the country’s finest public servants”.
Joe Biden pledged in March to name a woman on the ticket. He had faced mounting calls to pick a black woman in recent months as the nation has been convulsed by social unrest over police brutality against African Americans, a key voting bloc for the Democratic Party.
The White House has potsponed a meeting with Democrats and Republicans congressional leaders as lawmakers continue talks on raising the nation’s debt limit.
The talks were to take place between President Barack Obama, Vice-President Joe Biden and leaders of the Senate and House of Representatives.
The US government shutdown, also a result of the political deadlock, has now entered its third week.
Officials warn of economic calamity should the US default on its debt.
In a statement, the White House said Monday afternoon’s meeting had been postponed to “allow leaders in the Senate time to continue making important progress towards a solution that raises the debt limit and reopens the government”.
It is unclear when it will be rescheduled.

President Barack Obama sounded his own warning as he toured a soup kitchen for the poor in Washington D.C. earlier on Monday.
“This week if we don’t start making some real progress, both the House and the Senate – and if Republicans aren’t willing to set aside their partisan concerns in order to do what’s right for the country – we stand a good chance of defaulting,” he said.
“And defaulting would have a potentially devastating effect on our economy.”
Barack Obama said he saw “some progress” in the talks, ahead of Thursday’s deadline for the US to raise its $16.7 trillion borrowing limit or risk default on its debt.
Expected to attend the White House meeting were Senate Democratic Majority Leader Harry Reid, Senate Republican Leader Mitch McConnell, Republican House Speaker John Boehner and House Democratic Minority Leader Nancy Pelosi.
On Monday, Harry Reid told the Senate he was “very optimistic we will reach an agreement”. Mr McConnell also expressed optimism, following what he described as “a couple of very useful discussions” with the Democratic leader.
Republican Senator Susan Collins acknowledged the Senate did not have a finished agreement, but said senators were “making very good progress”.
A separate bipartisan group led by Susan Collins also met for several hours earlier in the day to discuss possible solutions, the Associated Press news agency reported.
Congressional Democrats are now said to be using the looming debt ceiling deadline as leverage to push back against previously enacted cuts to the US government budget.
Those deep military and domestic spending cuts, known as the “sequester”, went into effect in January 2013 after Democrats and Republicans failed to reach a budget compromise.
Italians have been voting in the final round of the contest for the leadership of the centre-left Democratic Party.
The run-off vote pitches veteran party leader Pier Luigi Bersani against Florence Mayor Matteo Renzi.
With the party leading opinion polls, the winner has a good chance of becoming Italy’s next PM in elections scheduled for early 2013, analysts say.
Those elections will choose a successor to PM Mario Monti’s government.
Mario Monti’s successor will face the challenge of addressing Italy’s deep-rooted economic problems.
Pier Luigi Bersani won the party’s primary on 25 November, winning 45% of the vote to Matteo Renzi’s 35.5%.
The two men are very different characters, with tieless, youthful Matteo Renzi, 37, painting himself as the voice of a new generation which wants to sweep away the entire class of older politicians.
By contrast, 61-year-old Pier Luigi Bersani is very much a figure from that older generation.

A minister in previous governments, he accepts that the leftist establishment that he represents has disappointed its followers in the past, but emphasizes the importance of experience.
Speculation has been mounting as to whether Silvio Berlusconi would run for a fourth term in office, with the ex-premier suggesting last week that he was thinking about returning to politics.
The billionaire tycoon’s record has been tarnished by sex and political scandals, and he resigned as prime minister in November 2012, after MPs approved an austerity deal to help curb the debt crisis threatening the eurozone.
Barack Obama has accepted the nomination of the Democratic party, telling voters they face a generational choice in November’s election.
The US president highlighted the differences between his aims and Republican policies, and reprised his 2008 theme of “hope”.
“I never said this journey would be easy, and I won’t promise that now,” Barack Obama told the Democratic convention.
Republican Mitt Romney is challenging Barack Obama for the White House, with polls showing a tight race.
Barack Obama told delegates in the hall and voters watching at home that the nation’s problems had built up over decades and could not be fixed in a flash.
“But when you pick up that ballot to vote – you will face the clearest choice of any time in a generation.
“Over the next few years, big decisions will be made in Washington: on jobs and the economy; taxes and deficits; energy and education; war and peace – decisions that will have a huge impact on our lives and our children’s lives for decades to come,” he said.

Barack Obama took the stage not in a huge stadium in downtown Charlotte, North Carolina, as organizers had hoped, but inside the convention centre after Thursday’s speech was moved because of weather concerns.
He followed a rousing speech by Vice-President Joe Biden, who praised Barack Obama for his bravery in bailing our the auto industry and ordering the killing of Osama Bin Laden.
The president offered a string of critiques of Republican policies, describing his opponents as “happy to talk about everything they think is wrong with America” without offering suggestions on how to make things right.
“That’s because all they have to offer is the same prescription they’ve had for the last 30 years,” he said.
“Have a surplus? Try a tax cut. Deficit too high? Try another. Feel a cold coming on? Take two tax cuts, roll back some regulations, and call us in the morning!”
But there was no mention of his own healthcare law, a signature achievement that remains unpopular with many Americans, and little explicit talk of the stimulus enacted in his first months in office.
The speech prompted a response from Mitt Romney’s camp: “Tonight President Obama laid out the choice in this election, making the case for more of the same policies that haven’t worked for the past four years,” his campaign said in a statement after the speech.
“He offered more promises, but he hasn’t kept the promises he made four years ago.”
Barack Obama also spoke about his energy strategy, saying the US had opened “millions of new acres for oil and gas exploration… and we’ll open more”.
“But unlike my opponent, I will not let oil companies write this country’s energy plan, or endanger our coastlines, or collect another $4 billion in corporate welfare from our taxpayers.”
On international issues, the president described Mitt Romney and running-mate Paul Ryan as “new to foreign policy”.
“But from all that we’ve seen and heard, they want to take us back to an era of blustering and blundering that cost America so dearly,” he said, highlighting his success with Bin Laden and his withdrawal of troops from Iraq and planned drawdown from Afghanistan.
As Barack Obama finished the speech, he roused the crowd by telling them their votes had helped make the changes of his presidency.
“Only you have the power to move us forward,” he said.
“I recognize that times have changed since I first spoke to this convention. The times have changed – and so have I. I’m no longer just a candidate. I’m the president.”
Earlier, Vice-President Joe Biden accepted his own re-nomination in an emotional speech that focused on family and national security.
“Folks, I’ve watched him,” he said of the president.
“He never wavers. He steps up.”
“He asks the same thing over and over again: How is this going to work for ordinary families? Will it help them?”
Joe Biden also criticized Mitt Romney for not backing the US auto industry bailout, referring to the former Massachusetts governor’s time leading private equity firm Bain Capital.
“I just don’t think he understood what saving the automobile industry meant, to all of America. I think he saw it the Bain way, in terms of balance sheets and write-offs,” he said.
“The Bain way may bring your firm the highest profit. But it’s not the way to lead your country from its highest office.”
The third and final night of speeches in Charlotte also saw former Florida governor Charlie Crist – who was previously a Republican – and Massachusetts Senator John Kerry address the convention.
John Kerry criticized Mitt Romney for surrounding himself with “neo-conservative advisers who know all the wrong things about foreign policy”.
“This is not the time to outsource the job of commander in chief,” the Massachusetts senator said.
Former Arizona Representative Gabrielle Giffords, still recovering from a near-fatal shooting on a meeting with her constituents in 2011, appeared on stage to lead the convention in the pledge of allegiance.
Walking slowly and steadying herself to recite the pledge, Gabrielle Giffords left many in the crowd dewy-eyed as she smiled through her recital.
Thursday’s speeches brought an end to the Democratic convention, which also headlined speeches from Michelle Obama and former President Bill Clinton.
Barack Obama and Mitt Romney now face two months of relentless campaigning before voters across the 50 states go to the polls on 6 November.
