King Charles III and Queen Camilla have officially begun their highly anticipated US tour, arriving at the White House for the first visit by a British monarch since 2007. Welcomed by President Donald Trump and First Lady Melania, the royal couple enjoyed a private tea and a garden tour before heading to a British Embassy reception under heavy guard. Buckingham Palace confirmed the four-day trip is proceeding exactly as planned, brushing off security fears sparked by a recent armed attack at a Washington correspondents’ dinner. The King’s packed itinerary features an address to Congress and a formal State Dinner, before the couple travels to New York to pay their respects at the 9/11 memorial.
