Overview

• Activists projected images on the castle walls on Sept. 16 that implied ties between President Donald Trump and Jeffrey Epstein, including an alleged obscene letter, a birthday message and Trump's mugshot.
• British police said four people were arrested on suspicion of carrying out an attention‑seeking public act with intent to defame, and the incident remains under investigation.
• Despite the protest, Trump met King Charles at Windsor on Sept. 17 and attended a royal banquet after a welcome parade held inside the grounds to limit disruption.
• Police estimated up to about 5,000 people joined protests in central London during the state visit, with a heavy security presence in the area.
• Trump had known Epstein years earlier but has denied involvement in Epstein's alleged crimes, which continue to fuel public scrutiny and calls for document transparency.
