The couple are self isolating at the White House, officials say.

Mr Trump has mild symptoms, but he's in good spirits.

His diagnosis has stunned America, causing financial markets to dip, and raises major questions about the remainder off the election campaign.

Well with the very latest Our North America editor, John So Paul, is at the White House forest tonight, John Clive.

If this doesn't sound contradictory, the news that broke up one o'clock this morning was simultaneously astonishing, a mind boggling on not in the least bit surprising, astonishing, a mind boggling.

Because Donald Trump is the most protected man in the world.

He has tested daily for the coronavirus, not a tall, surprising given the very lax, lackadaisical attitude towards face masks that you see in the White House.

Although palpably, it was a different atmosphere today, as you know tonight's Al Smith Last night, in what now appears to be grim irony, the president made a speech from the White House about the pandemic.

The worst was behind us he said.

I just want to say that the end of the pandemic is in sight and next year will be one of the greatest years in the history of our country.

But then later that evening came a bombshell statement that will reverberate around the world.

The most serious health issue toe affect a serving president in decades.

He tweeted tonight, the first lady and I tested positive for Covert.

19 will begin.

Our quarantine on recovery process immediately will get through this together today.

The President's chief of staff gave reporters this update.

The president The first lady tested positive for covert 19.

Uh, they remain in good spirits.

Uh, the president does have mild symptoms.

Ah, hint of something being wrong came earlier in the evening last night when it was announced that this woman hope Hicks had contracted the virus.

On Wednesday, she was part of the inner circle to travel with the president on the cramped Marine one helicopter.

None of them is wearing a mask.

AST Donald Trump seemed to dance with joy at the rally in Duluth, Minnesota.

She'd become symptomatic on was quarantined on Air Force One for the return journey to Washington.

The ripples of concern will reach everyone who's been in close contact with the president, not least Joe Biden, who shared a debate stage with him for a shouty 90 minutes on Tuesday night, a debate where the president ripped into the Democratic candidate for his mask wearing.

I don't wear most like him every time you see him.

He's got a mask he could be speaking 200 ft away from, and he shows up with the biggest mask I've ever seen on.

It was noticeable that none of the Trump entourage wore face coverings that actually violated the rules of the Cleveland Clinic, which was in charge of all the safety issues in inside the hall, which were that everybody except for the president, the vice president and I were not supposed to wear mask.

I mean, we're supposed to wear masks.

The president has worn masks in public on less than a handful of occasions, and his ambivalence towards them is evident.

Can you take it off?

Because I cannot hear.

I'll just speak louder, sir.

You want to be politically correct.

We just don't wanna wear one myself.

It's a recommendation.

They recommend it.

Um I'm feeling good on.

He's been holding rallies, as though Cove it was in the rear view mirror, with thousands turning up.

No attempts at social distancing, few wearing masks today, messages of support from around the world.

This from Boris Johnson, who's bean where the president is now.

Obviously, I think we all want to send our best wishes to the president and the first lady, and I've done that this morning, as you could imagine on.

But I'm sure that they'll both stage a very strong recovery.

Um, messages of support to from political rivals.

This from Joe Biden, who's tested negative today, sending my prayers for the health and safety of the first lady and president uh, president, United States.

After they tested positive for Kobe, 19 my wife, Jill, and I prayed that they'll make a quick and full recovery.

This is not a matter of politics.

It's a bracing reminder to all of us that we have to take this virus seriously.

But another leading Democrat, the speaker of the House, Nancy Pelosi, comes very close to saying to the president, Serves you right.

This is tragic.

It's very sad, but it also is something that again, going into crowds unmasked and all.

The rest was sort of, ah, brazen invitation for something like this to happen.

This is first and foremost a medical issue for the president and his wife, but it's upended.

A presidential election campaign that needed no further agitation with many questions begged a few answers to give at this early stage.

John so pulled BBC news at the White House.

Well, with a month to go before the presidential election, what impact could Donald Trump's illness have at the ballot box on North America?

Correspondent Nick Bryant reports now from Michigan.

The lock down is a scam.

The Kobe interests are the coronavirus has opened up yet another fault line in an already fractured country.

These militiamen, part of a protest of those who see the co vid restrictions a za threat to American liberty.

It was packed with supporters of Donald Trump, most of them, still not wearing masks on began with heads bowed in prayer for the president.

If we could take, like, five seconds to say a prayer for the guy, that's okay, Lord, we pray for President Trump his family for a swift recovery, and I understand he's got some mild symptoms, but I think he'll probably be over them soon, and it will be a victory for him.

A victory.

What was the victory in showing that?

There's a lot of overreaction to this Covitz stuff?

I just hope he pulls through it.

Do you think he took enough precautions?

Do you think he should have worn a math?

No, I think everybody.

This is a free country and everybody should be not be dictated.

Thio and everybody shouldn't have to wear a mask if they don't want Thio.

This'll was another covert protest of childcare.

Workers bemoaning the lack of financial aid on their responses to the overnight news.

Spoke of how an American democracy.

Right now, there's not even on agreed upon set of fax e Don't believe it.

Why don't you believe it?

I think it's just deployed because he did so bad debating he did horrible in the debates, so I think it's a ploy to get out of debating again.

And if he does have it, I don't believe it.

I can't even say if he does have, but I just don't believe it.

Michigan is a key battleground state that Donald Trump won unexpectedly in 2016.

But there aren't so many Trump Yard sign says there were four years ago.

We've fallen flat on our face.

Jack Spielman is a lifelong Republican who supported him back then, but he's already voted for Joe Biden, partly because of the president's mishandling of covert.

Initially denied it, called it fake news blamed on the Democrats, blamed it on the Chinese.

Then he transitioned and said, It's going to go away like magic.

Then it was going to go away.

When the heat comes, then we're gonna have.

Then we just had to deal with it, and then it was We're gonna have a vaccine just before the election.

I can't trust anything, he says with it.

In a bygone political age, the nation might have rallied behind the leader suffering from a virus that has killed so many of his compatriots.

But this is such a deeply divided America on.

This is such a deeply divisive American president.

Even this pandemic has become an accelerant of political polarization.

Nick Bryant, BBC News, Michigan It's well known that the older you are and the heavier you are, the higher the risk of having serious complications.

With Covert 19 our medical editor, Fergus Walsh, looks at the risk to the president's health.

Donald Trump has several factors which raised his risk profile for coronavirus, his age weight on being a man.

At 74 he's often insisted how healthy he is.

Despite a love of burgers on hot dogs, Age is the biggest risk factor for Kobe in 19 in the United States, eight out of 10 deaths have been among the over 65.

The risk of dying for someone aged 65 to 74 is 90 times higher than for someone in their twenties now.

To put that in context, a recent international study found that once infected with coronavirus, the chances of dying were around one in 100 at age 65 1 in 25 at 75 1 in seven.

At 85 the president and first lady of the United States, the first lady, Melania Trump, is just 50 24 years younger than Donald Trump on physically fit her risks from co vid should below.

The president is 6 ft three and weighs more than 17 stone, putting him in the obese category, another red flag.

His medical team will be on constant guard for any change in his condition.

Often, patients have quite mild symptoms to start with, and then it says if they drop off a cliff and suddenly it gets worse and that can happen really within hours, I don't think that could be sure for approximately 10 days.

If then He really hasn't developed any worse symptoms.

Hey seems to be controlling the virus in his in his throat and his nose.

Then I think they will relax.

I have I still have a temperature.

And so it was.

Nine days after testing positive for coronavirus before Boris Johnson was admitted to hospital in early April, he spent three nights in intensive care and says the NHS saved his life.

Another leader who got co vid was President Bolson are a of Brazil.

He had few symptoms and dismissed the virus as a measly cold.

It's impossible to predict how any individual will cope with Cove it.

Many people never develop any symptoms at all on there are treatments now which have helped improve survival rates for what can be a brutal disease.

Fergus Horse, BBC News under North America Editor John Sir Paul is at the White House John November, the thirties.

Election Day, a little more than four weeks away.

Where does the president's illness leave the campaign?

Let me give you a bit of geography of where I'm standing to help answer the question, if I might, in front of me eyes the West Wing of the White House, where the Oval Office is, where the president would normally be working.

Except he's not now because he is in the East Wing, which is also where the residences and where he is now convalescing we and the longer he is there, the less normal this campaign will be.

Now we've had a bit of an update of a medical bulletin that he has been given an antibody cocktail on infusion that was completed without incident.

We're told the president is fatigued, but in good spirits.

And apparently the first lady has a mild cough and headache, but otherwise not too bad where it leaves the politics.

I mean, the next presidential debate was due to take place in 12 days time.

That seems highly unlikely.

There were a whole series of rallies that the president was going toe hold.

They will be off.

He's not going to be able to go to those on.

It may be that he'll do zoom calls if his health improves.

But there's one critical thing in all of this Clive and it's this.

Donald Trump wanted the last four weeks of the campaign to be about anything but cove it.

Now that he's contracted coronavirus, it is going to remain absolutely center stage.

Okay, John.

Thank you for that, John.

So, Paul, there at the White House?
