In an uproarious trip to Europe, Trump harangued members of the North Atlantic Treaty Organisation military alliance, scolded Germany for its dependence on Russian energy and shocked Britain by publicly criticising Prime Minister Theresa May's Brexit strategy. "They didn't!" Acosta had objected to Trump dismissing the news outlet as "fake news".
After three days of anti-Trump demonstrations, the US President has finally seen some protesters in the UK.
Trump has repeatedly said the investigation into suspected Russian interference in the 2016 USA election - which he casts as a "rigged witch hunt" - makes it hard for him to do substantive deals with Moscow. Greenpeace said police had been given a ten to 15-minute warning.
He added: "The weather is attractive, and this place is incredible!"
Trump is spending the weekend out of the spotlight, staying at his resort in Turnberry in western Scotland ahead of his summit with Russian President Vladimir Putin in Helsinki, Finland.
'Shame on you'- Donald Trump's not-so-welcoming welcome to the UK
The Sun said its interview with Trump was conducted in Brussels before he left for the British leg of his trip. London mayor Sadiq Khan has given the okay for a giant orange blimp to fly over the streets of the capital.
Putin held several meetings in the Kremlin, including talks with Palestinian leader Mahmoud Abbas.
Pompeo - formerly director of the Central Intelligence Agency - added that it's "very important" that Trump and Putin meet.
Trump denies that he or any campaign aides were involved with the Russian campaign and repeatedly dismisses the ongoing investigation that produced Friday's indictments as a "witch hunt".
The charges shine an even brighter spotlight on Trump's treatment of Putin, who has repeatedly denied that Russian Federation sought to skew the election that Trump, a Republican, unexpectedly won.
The president concludes his United Kingdom visit on Sunday, before travelling to Helsinki for talks with Russian President Vladimir Putin. He will be holding meetings and playing golf before setting off to meet Vladimir Putin on Monday in Helsinki.
In that, he tells people to "overshoot" - asking for far more than they ever expect.

The players accepted the criticism they received, they took it on board and improved. We'll be well prepared because this is a one in a lifetime opportunity.
Trump has said he plans to raise the issue. Trump mocked network president Jeff Zucker as "Little Jeff Z" following a spat with a CNN correspondent at a news conference Friday in Britain.
"A famous golf course owner from America who, I think, has now turned his hand to politics, chose to take the Scottish government to court to try to block these wind turbines", she told reporters.
"That's why I'm protesting against Trump", she added before yelling towards the hotel where Trump is staying: "That and the caging of babies - you big fat roaster!" "I don't think you'll have any 'Gee, I did it".
A Greenpeace activist swooped on a powered parachute within a few hundred yards of the president as he stood outside the golf course's hotel on Friday evening.
Mr Trump remained composed and moved inside as the parachute approached, surrounded by his security detail. Neighbors have accused Trump of harassment and bullying to get them to sell land; a local fisherman became a national hero of sorts when he refused to sell to Trump, despite a $690,000 offer.
Yet the President was not without his supporters, with International Trade Secretary Liam Fox labelling the demonstrators "an embarrassment to themselves".
Top Democrats Ask Trump Not To Meet Putin Alone
In 2016, Obama immediately called a bipartisan meeting after he was informed that Russian officials had meddled in the election. Officials at the time said "no more than about 200,000" voters had been affected by a cyber-hacking of the registration rolls .
