King Charles III begins four-day US state visit to mark America's 250th birthday and reinforce US-UK ties

King Charles III's state visit to the United States — his first as monarch — unfolds against a backdrop of both celebration and diplomatic strain. Presidential historian Douglas Brinkley of Rice University told the Associated Press that Charles faces the challenge of separating the monarchy from current political friction, noting that "politics come and go, prime ministers, presidents, come and go, but there's something deeper about the special relationship between the United States and the U.K."

The trip was arranged by the British government despite pressure on Prime Minister Keir Starmer to cancel it after President Trump publicly criticized Starmer's refusal to support U.S. policy on Iran and made disparaging remarks about Britain's military record in Afghanistan. The AP reported that Trump has nonetheless continued to speak warmly about Charles personally, and Brinkley said history suggests Trump "really tries to be impressive whenever he's dealing with British royalty."

A central moment of the visit will be Charles's address to a joint session of Congress, where observers say he is expected to echo themes set by Queen Elizabeth II in her 1991 congressional address — democratic values, the rule of law, and the durability of the Atlantic alliance. Robert Hardman, author of a biography of Elizabeth II, described Charles's message to the AP as: "No hard feelings, it's been a great divorce, we've had a lovely 250 years and let's reflect on the high points."

The itinerary includes a commemoration of the September 11, 2001, attacks, a ceremony honoring fallen service members, and an event attended by Queen Camilla marking the 100th anniversary of A.A. Milne's Winnie the Pooh stories. Certain topics are expected to be deliberately avoided: the AP reported there are no plans for Charles to meet with victims of Jeffrey Epstein — despite calls for him to address his brother Prince Andrew's links to the convicted sex offender — nor any planned meeting with his son Prince Harry, who lives in California after stepping back from royal duties.

CNN's coverage, drawing on commentary from Patrick Jephson — former private secretary and chief of staff to Princess Diana — described the visit as presenting a "delicate tightrope" for the King, given the competing political sensitivities surrounding the trip. The AP's coverage placed greater emphasis on the historical precedents set by previous royal visits dating to 1939, when King George VI became the first British monarch to visit the United States, and on the continuity between Charles's mission and that of his late mother.
