John Yes.

When Donald Trump left the White House this morning to go and play golf, counting was continuing.

Nothing had Bean declared.

By the time he comes off the 18th green, someone is going to have to tell him that Joe Biden is president elect on that the race has been called for him.

Now Donald Trump is not conceding anywhere near his lawyers.

His legal team insist they're going to fight and they have got grounds, although what those grounds are are still not clear.

Nevertheless, Joe Biden, at the age of 77 on exactly 48 years after he first became a senator, is now going to become America's 46th president.

On It should also be added that Kamala Harris will become the first woman vice president first woman of color in such a lofty position in America.

Outside, on the streets in Washington, the soundtrack is of honking car horns.

The tension has been relieved.

After five days of waiting.

In cities across America that tend to be more liberal.

This morning, Donald Trump went off to play golf, something he'll soon have a lot more time to do.

Although the reality of this situation was made clear to him as the motorcade swept into his golf club, the president throughout has been tweeting furiously, getting full caps.

Lock one red.

I won this election by a lot Last night, Joe Biden gave another holding statement increasingly confident, assured that the tide of history is flowing in his direction.

We don't have a final declaration, a victory yet, but the numbers tell us it's clear.

Tell us a clear and convincing story.

We're going to win this race.

Biden, at 77 years old, will become America's oldest president in temperament and outlook.

He is the opposite of Donald Trump, but he'll inherit a bitterly divided country.

The president is determined to fight.

His lawyers are fanning out across the country.

But what's the case?

There are allegations of plenty but substances thin.

It may be that Donald Trump's tenure is ending on the word that he hates the most will attach to him loser as he moves towards the exit.

John So Paul.

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 Tina.

It has been such a long political journey began in the early seventies when he won election to the U.

S Senate.

It took him to the West Wing, where he was the vice president of Barack Obama.

But now he will sit behind the desk in the Oval Office.

The White House will become his home.

He loves quoting the words of the Irish poet Seamus Heaney about when hope and history rhyme today.

That's happened for him.

I've 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.

Barton quit work for the BBC BBC.

I'm Irish Joe Biden.

The White House has long been 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 slot.

The vice president, Barack Obama.

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

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 on cast himself as the anti trump, almost portraying this election a za 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 from when the results first started coming in on election night.

It's beena, sometimes fretful, wait for the supporters of Joe Biden, but now will be able to celebrate.

This, finally, is his moment.

2020 is his year.

Nick Bryant, BBC News, Delaware This US election has seen the highest turnout since 1900.

So far, Mr Biden has won more than 73 million votes, the most ever for a U.

S presidential candidate.

Mr.

Trump has drawn almost 70 million, the second highest tally in history on North America.

Editor John So Paul joins us again.

John.

What happens next?

What happens next is we wait to see what Donald Trump does.

I don't think there is any sign that he is going to concede any time soon.

As I said in my report, the word he hates most of all is loser.

But Donald Trump.

If everything stays as it is, and there's no reason to believe that it won't, he will become only the third president in the last 50 years to fail to win a second term.

He will join Jimmy Carter on George H.

W.

Bush in that kind of Hall of infamy, if you like on DSO, Donald Trump will want to fight.

Joe Biden is going to go full steam ahead as if everything is normal, that he is going to proceed according toe all the constitutional norms.

He will start getting security briefings.

His security detail will be beefed up.

Aunt, he will start acting as the president of the United States on his number.

One job, of course, at the moment would be when he takes office to deal with the coronavirus, but on, um, or grandiose scale.

It will be healing the divisions of America.

After four years of a very divisive, unique president on that will take some time.

There will be challenges of plenty for Joe Biden, but at the moment, he is going to enjoy this moment of celebration, John.

Thank you, John.

So poor in Washington.
