But it is unlikely the Trumps even saw them.
We're more than used to our best sports-stars and celebrities being picked up as "British" in the English media when they're on the rise, and "Irish" when they're underperforming or in trouble.
Before the Sun interview was published, Ms May invoked Winston Churchill as she addressed Mr Trump and business leaders at a black-tie dinner at Blenheim Palace, the grand 18th-century country house which was the British World War II leader's birthplace.
Speaking in Brussels as he wrapped up a contentious North Atlantic Treaty Organisation summit, Trump shrugged off concerns over demonstrations, saying he had "great friendships" in Britain, where his mother was born.
The antipathy between Mr. Trump and segments of the British public started during the 2016 presidential campaign, when Mr. Trump called for a temporary ban on Muslims entering the United States.
"It's a disastrous and divisive time, and Trump is very much part of that", he said. "I think it changed the fabric of Europe and, unless you act very quickly, it's never going to be what it was and I don't mean that in a positive way". "I don't know [if] that is what they voted for", he added.
In an interview with The Sun, he shoots down the chances of a trade deal with the USA if she sticks to her carefully crafted compromise Brexit plan. "Now, for the benefit of all our people, let us work together to build a more prosperous future", she said.
A protest will also be held outside the president's Balmedie golf course in Aberdeenshire on Saturday, and it is expected there could be further demonstrations at his Turnberry resort in South Ayrshire.
Winfield House is the only place where Trump will spend time in central London, where demonstrators are expected to gather in their tens of thousands for a march on Friday afternoon, hours after a giant "Trump baby" balloon is flown near the UK Parliament in an eye-catching stunt.
More than 50,000 people have signed up to demonstrate in London, where they intend to fly an oversized balloon depicting the president as an angry baby in a diaper.
The state visit has never been scheduled - there is fierce opposition to it in many quarters of Britain - and this trip is part of a working visit instead, meaning, among other things, that Trump will overnight at Winfield House, the US ambassador's handsome residence near Regents Park rather than in Buckingham Palace or Windsor Castle as a guest of the queen.
A helicopter took them from the airport to the United States ambassador's residence here.
Trump will depart Britain Friday for Finland to prepare for a summit with Russian President Vladimir Putin Monday in Helsinki.
Whilst Trump's trip is not the full state visit he was originally promised, he was heralded by military bands on his arrival in the country and at Blenheim, and on Friday he will have tea with Queen Elizabeth.
Lance Price, who served as former Prime Minister Tony Blair's media adviser, told the Independent that no matter what the American convoy contends, the fact that Donald Trump is avoiding London points to a moral victory for the protesters.
