Hello and welcome to NewsHour live from the BBC World Service in London. I'm Rebecca Kesbby.

So we begin in Washington, D.C., where today it was the German Chancellor Frederick Meerts's turn to meet President Trump in the Oval Office.

These meetings with world leaders at the White House

can end up being quite dramatic, but today the drama happened after the Mets meeting.

As President Trump's formerly close friend and advisor, tech billionaire Elon Musk, responded with

a series of explosive posts on social media to comments Mr Trump gave to reporters in the Oval Office.

The two men have been disagreeing, mostly amicably, for weeks now over at President Trump's new tax legislation,

the so-called Big Beautiful Bill.

But President Trump was asked about that today by reporters, and it was these comments that seems to have sent Elon Musk into a rage.

Elon and I had a great relationship.

I don't know well anymore.

I was surprised because he said wonderful things about me.

You couldn't have nicer said the best things.

But I'm very disappointed because Elon knew

the inner workings of this bill better than almost anybody sitting here. And if you saw the statements

he made about me, which I'm sure you can get very easily, it's very fresh on tape. He said the

most beautiful things about me. And he hasn't said bad about me personally, but I'm sure that'll be next.

But I'm very disappointed in Elon.

I've helped Elon a lot.

Well, it was next, as Mr. Trump anticipated.

These remarks did not go down well with Elon Musk,

who immediately took to his social media site X to make his views known.
