The Scots are generally not fans of Mr. Trump, and protests were already planned for Saturday. A group called “Stop Trump Scotland” said it was organizing a “festival of resistance” against Mr. Trump during the trip and has called on John Swinney, the first minister of Scotland, to cancel plans to meet with him.

European Commission President Ursula von der Leyen headed to Scotland on Saturday ahead of a meeting with U.S. President Donald Trump on Sunday afternoon, Commission spokespeople said, as officials from both sides said they were nearing a trade agreement.

President Donald Trump landed in Scotland Friday evening for a five-day visit and delivered two blunt messages for Europe: "stop the windmills" and control immigration, which he said is "killing" the continent.
