King Charles III left Washington with the same goodwill from U.S. President Donald Trump that greeted him when he arrived three days earlier as Trump hailed him as "the greatest king,¡± adding "we need more people like that in our country.¡±

For a moment at least, Washington has publicly reaffirmed its interest in preserving the so-called special relationship with the United Kingdom.
