AMNA NAWAZ: President Trump, meanwhile,# is himself facing ongoing questions about## the Epstein files.

He spoke about Andrew's# arrest on his way to Georgia this afternoon.

DONALD TRUMP, President of the United States:# I think it's a shame.

I think it's very sad.

I## think it's so bad for the royal family.

It's a# very, very sad -- to me, it's a very sad thing.

AMNA NAWAZ: For more on the# fallout in the United Kingdom,## I spoke earlier today with BBC studio# special correspondent Katty Kay.

Katty Kay, welcome back to "News# Hour."

Thank you for joining us.

KATTY KAY, BBC: Thank you for having me, Amna.

AMNA NAWAZ: So, this moment, the# arrest of the brother of a monarch,## just how extraordinary and# unprecedented a moment is this?

KATTY KAY: Look, we have known for a while# that Andrew had this shadow over him.

He'd## lost his titles.

He'd been alienated by# the world family.

He wasn't showing up to## Christmas events and holiday events.

He didn't# appear in any of the family photographs anymore.

So we knew that there was this cloud over# Andrew.

And yet I think, despite that,## I can't tell you how stunned people were in the# U.K.

I have been getting texts from people in the## U.K.

all day saying, this is front-page news.# Is it front-page news in the United States?

Which, clearly it is.

And it's because# it is unprecedented.

You have to go back## to 1647 for a monarch to be arrested# like this in the United Kingdom.

And## I think there's now -- of course, it begs# a lot of questions about the royal family.## It puts a real spotlight on the# process of the Epstein investigation,## and it raises questions about what is happening in# the U.K.

compared to what's happening in the U.S.

But, yes, everybody's stunned.

AMNA NAWAZ: And the reaction that we saw from# King Charles himself, right, ba.. in and saying the law has to take its course# now on the investigation, was that a surprise?

KATTY KAY: So what's unusual about that, and it's# something that may not have been picked up here,## is that he signed it himself.

That# statement is signed by Charles R. Normally, statements like that, Amna, come# from Buckingham Palace or the palace.

It's## very unusual for the monarch to put# their own name after a statement.

And## I think it was a sign that the king# was trying to show the British public## that he is fully supportive of this# investigation, wherever it may lead.

Now, he's already said that in public,# but the fact that he came out and he made## that statement about how the law# has to take its course, I think,## shows how desperate the royal family is# to say, this is Andrew's issue.

This is## not about the rest of the British royal family,# because this could be a huge body blow to them.

So they have to try to make this --# if they can, they have to try to show## the British public they're supporting the# investigation.

This is about one individual,## one bad apple.

It's not about the king,# and it's not about William and Catherine.

AMNA NAWAZ: And I want to underscore# here something.

This is not related## to the allegations that were made by the late# Virginia Giuffre, who said she was trafficked## by Jeffrey Epstein to Britain and had sex# with Andrew when she was a teenager years ago.## Andrew has consistently denied any wrongdoing# there.

And Giuffre died by suicide last year.

But her family today did praise# the arrest.

They said: "Today,## our broken hearts have been lifted at the news.# No one is above the law, not even royalty."

Katty, on those allegations, is that something## that people in Britain want# to see investigated further?

KATTY KAY: Ever since Andrew did that# disastrous interview with the BBC,## in which he failed to express any sympathy# for the survivors of Jeffrey Epstein,## that's been when he started to be shunned# by royal society and shunned in public life.

And I think there is a demand for# more information about that.

Now,## the issue for the royal family, which,# as I said, is trying to insulate itself,## is that if this goes to trial, there# are going to be awkward questions asked## to the royal family about the $15 million civil# settlement that Andrew paid to Virginia Giuffre.

Where did that money come from?

Did it come# from entirely Andrew?

We don't know.

All of## those finances have been so far kind of clouded in# secrecy.

It just came from the royal purse.

Well,## did it come from the king?

Did it come from only# Andrew?

Were there other sources of that money?

I think that's the kind of information that the# British public would like more answers to, and,## clearly, the American Congress# wants answers to as well.

AMNA NAWAZ: Another thing we have been reporting# on here is sort of the disparity of consequences## and accountability we have seen with the Jeffrey# Epstein files being released in some form,## investigations and resignations at very high# levels across Europe, not so much here in the U.S.

Is that resonating in the U.K.?

KATTY KAY: What we have had in the U.S.# is more private sector resignations and## stepping back from public light.

So you have# Bill Gates not attending an A.I.

summit,## speaking at an A.I.

summit in India, for example.

But then you don't get the investigations.# You don't get all of the information.

People## just step down from something.

They pull# back from public life.

They resign from a## high-profile business career, but it's# not the same as it being investigated.

And I think that's what the disparity# is, that you have actual investigations.## If Andrew goes to trial, it will be the Crown# Prosecution Service will conduct this.

The## Crown Prosecution Service will conduct,# will bring this trial to into fruition.

And it will be the king versus Andrew Mountbatten.# And I think that's what is the difference,## is that there is a perception in the U.K.# that the law is being applied equally.## Andrew Mountbatten-Windsor will be sitting in# a cell during this time waiting to find out## what he's going to be charged with.

And he will# be treated like a normal member of the public.

There are no favors being granted to him just# because he is the brother of the king.

And I## think that is what people are noticing# in the U.K.

and pointing to in the U.S.

Are people being protected?

Are certain# people not being investigated who should## be investigated?

And can we trust the reliability# of the Justice Department to follow through with## the rule of law in the way that the Crown# Prosecution Service now seems to be doing,## with the full blessing of King Charles, to be# honest and frank and do its job in this case?

AMNA NAWAZ: Katty Kay,# always great to speak to you,## especially at this extraordinary# moment in time.

Thank you so much.

KATTY KAY: Amna, thank you.
