Britain's King Charles III and Queen Camilla are greeted by US Protocol Chief Monica Crowley (L) and Isla, 9, daughter of British embassy staff, and Sam, 8, child of Commander Gordon Clarke with Royal Navy in the US as they arrive at Joint Base Andrews, Maryland, on April 27, 2026. King Charles III arrives in Washington Monday for a high-stakes state visit aimed at salvaging Britain's frayed ties with Donald Trump, amid extra-tight security following an attack on a gala dinner attended by the US president. Tensions over the Iran war have rocked the so-called "special relationship" ahead of a trip that was meant to mark the United States' 250th anniversary of independence from the British monarch's ancestors.
