The emotions were probably in that order.

They're celebrating a zero.

Their team has just won the World Cup way cleaner.

We cried four years ago, way went out on our rooftops and screamed in Shame for our country on.

Now we're screaming, Enjoy.

Just listen to Washington soundtrack.

Today there is celebration going on after five days of tension, which has now dissipated on this will be echoed in cities across the land.

But for all the joy in the city's Trump supporters, Air enraged, believing the president's claim that the election has been stolen, that there's been fraud, that the man they put their trust in is being turfed out unfairly.

Donald Trump this morning left the White House to go and play golf, something he'll soon have a lot more time for.

But even driving into his club, the reality of this situation was brought home to him.

This has been a week where everything seems to have come up short, though ever the showman he stopped to pose with a couple getting married.

Thea President is determined to fight.

His lawyers are fanning out across the country.

But what's their case?

There are allegations of plenty, but substance seems thin.

BBC NEWS Washington For the president elect, now 77 it's not only been a long few days waiting for this result, it's been decades trying to fulfill a lifetime ambition.

Mr.

Biden announced his first campaign for the White House back in 1987 on North America.

Correspondent Nick Bryant joins me now from the Democrats headquarters in Delaware.

Nick, they're preparing for this drive in victory rally here tonight.

Part of this long and extraordinary political journey that began in the U.

S Senate.

It went to the West Wing, where Joe Biden served as Barack Obama's vice president.

But now he gets to sit behind the desk in the Oval Office.

The White House will become his home Now.

Joe Biden loves quoting the words of the Irish poet Schamus hearing about how hope and history rhymes well, today.

That happened for Joe Biden.

He's got one of the most electrifying smiles in US politics and how he must be rejoicing.

Now at the age of 77 Joe Biden has fulfilled his personal American dream.

He's about to become the occupant of the White House thing.

Former vice president was the candidate who offered soft jazz after the heavy metal of the trump years.

Easy listening, moderation, a presidency Americans could have on in the background.

Eight years of Donald Trump can fundamentally change who we are.

I really mean it in a significant way.

He was never the most inspiring of candidates, but his geniality made him hard to demonize.

Mr.

Biden, quit work for the BBC BBC.

I'm Irish Joe Biden.

The White House has long being the target of his ambitions.

He announced his first presidential bid in 1987 and he tried again in 2000 and eight but ended up getting the second.

Sloss is the vice president, Barack Obama.

It's also gives the Internet one last chance toe talk about our bromance.

Yeah, despite the generation gap, they developed a bond like brothers.

It was sealed when Barack Obama awarded him the Presidential Medal of Freedom recognition to this pillar of the Washington establishment of his decades in public service.

His personal narrative is one of recurring grief.

In the early seventies, he lost his first wife and baby daughter in a car accident.

Five years ago, he had to bury his grown up son, Beau, who died of cancer.

It's a life story that found an echo in these sorrowful times.

I'd like to be able to say we're gonna be back to normal next Friday.

The coronavirus meant he spent much of the year sequestered in his Delaware home.

He almost became the invisible candidate, a time when the method of campaigning became a campaign issue in itself.

He kept his social distance and cast himself as the anti trump, almost portraying this election is a battle of good versus evil.

If you entrust me with the presidency, I will draw on the best of us.

Not the worst.

I'll be an ally of the light, not the darkness.

Yeah, from when the results first started coming in on election night, it's beena, sometimes fretful way for the supporters of Joe Biden.

True, but now they can celebrate.

This, finally, is his moment.

2020 is his year.
