Britain's King Charles and Queen Camilla wrapped up their four-day state visit to the US today with a quick stop by the White House to bid farewell to President Donald Trump, having already charmed him at a formal dinner two days prior. After barely six minutes indoors, Charles, always fond of the countryside, and Camilla departed to spend their final hours in small-town America and Appalachian wilderness: marching bands, Little League baseball, bluegrass music, sheep farmers and the bird-filled Blue Ridge Mountains. The official reason for the royal US trip was to mark the 250th anniversary of the US winning its independence from monarchy and British colonial rule under Charles' forebear George III. 🇺🇸 Farewell and thank you for the warmth of your welcome and the kind support you gave us throughout our first visit to the US as King and Queen, in this, your special anniversary year. We leave a piece of our ❤️ behind and take a little of yours back home with us.…
