Charles and Queen Camilla had arrived the day before and attended a large British embassy garden party with more than 600 guests. The Queen admitted feeling "slightly jet lagged." Speaker Mike Johnson described the King as "very personable" after speaking with him at the event.
The King is scheduled to address a joint meeting of Congress — only the second British monarch to do so after Queen Elizabeth in 1991 — and later join President Trump and First Lady Melania Trump for a state dinner that evening.
