While Trump took tea with Queen Elizabeth, a USA federal grand jury charged 12 Russian intelligence officers with stealing data from the campaign of Democratic presidential candidate Hillary Clinton. Is it actually a summit, or more of a meeting?
Trump has been reluctant to criticize Putin over the years and has described him in recent days not as an enemy but as a competitor. Nobody knows the answer to these questions. But we can predict with certainty that one subject is unlikely to dominate the strangely private tete-a-tete: the whole Russia-hacking-the-2016-election thing.
On the eve of his meeting with Russia's Vladimir Putin, U.S. President Donald Trump rattled allies once more by labeling the European Union a "foe" with regard to trade. His answer was not exactly reassuring.
President Trump included the European Union when rattling off a list of the "biggest foes" of the United States throughout the world. "But I don't think it's bad for the president that this is out there because it's clear he has to raise it". I hadn't thought of that. "They were doing whatever it was during the Obama administration", he said.
Despite the doubts of his top national security advisers, Trump is keen to withdraw U.S. troops from eastern Syria, where they have been battling the Islamic State. "If we could develop a relationship which is good for Russian Federation, good for us, good for everybody, that would be great". I've been told that by a number of people. Europe is still a more important partner for Russian Federation than the U.S., and they also share a similar diplomatic stance on many global problems. And I think you can have no doubt, Mr. President, that this is an investment in common American and European defense and security.
They are accused of using keystroke reading software to spy on the chair of the Democratic National Committee (DNC) and hack into the party's computers. Russian Federation has denied involvement in the hacks. Since then, he has consistently questioned whether the country was really to blame, contradicting the judgment of 17 USA intelligence agencies.
Sen. Rand Paul, R-Ky., said it's inevitable that Russian Federation will interfere in USA elections and that it's pointless for Trump to confront Putin about it.
Sen. Chris Murphy, D-Conn., rejected Bolton's assertion that the indictments put Trump in a stronger position going in to the meeting.
But in a series of Twitter posts on Sunday, Trump - or more likely Dan Scavino, Jr.
Trump was in Britain as part of his European trip that earlier saw him in Brussels for a North Atlantic Treaty Organisation summit and will take him to Helsinki for a summit with Russian Putin on July 16.
A massive security operation was in place at Turnberry and Police Scotland are investigating after a paraglider flew over the area on Friday night with a sign claiming Mr Trump is "well below par".
At the same time, thousands of people marched through Edinburgh to demonstrate against the USA president, following widespread protests on Friday with a massive march in London and events staged in cities including Glasgow and Belfast.
