King Charles to address Congress during historic US state visit

Buckingham Palace chose a moment of unease to stage a message of continuity. King Charles III and Queen Camilla were on a four-day state visit to the United States from Monday, April 27, through Thursday, April 30, and Charles was scheduled to address a joint meeting of Congress on Tuesday, April 28, a rare honor for a British monarch and the first U.S. state visit by one since 2007.

The timing sharpened the symbolism. Palace officials and congressional leaders linked the trip to the 250th anniversary of American independence and to the long-running U.S.-U.K. relationship, while Charles was expected to defend democratic values in his speech and express sympathy after Saturday’s shooting at the White House Correspondents’ Association dinner in Washington. The attack sent the president, first lady Melania Trump and other officials rushing away under security escort, and it raised the level of caution around a visit already loaded with diplomatic meaning.

Buckingham Palace said on Sunday, April 26, that the visit would go ahead as planned after discussions on both sides of the Atlantic. The decision kept the king’s first state visit to the United States moving forward even as the trip unfolded against strains in the wider alliance, including tensions tied to the war in Iran and broader disagreements involving President Donald Trump and Prime Minister Keir Starmer.

Congress invited Charles on April 1 in a joint statement from Speaker Mike Johnson, Senate Majority Leader John Thune, Senate Minority Leader Chuck Schumer and House Minority Leader Hakeem Jeffries. Their invitation cast the address as a celebration of American independence and the special relationship between the two countries, but it also functioned as a public reminder that the monarchy is still used as a diplomatic instrument when London wants Washington to hear more than protocol.

Charles became only the second British monarch to address a joint meeting of Congress, following Queen Elizabeth II, who spoke on May 16, 1991. Roughly 800 people attended that address, which drew a standing ovation inside the Capitol and protests outside over British policy in Northern Ireland.

This time, the pageantry carried a sharper political purpose. By sending Charles to Congress after a security scare in Washington, Buckingham Palace was signaling that the alliance is meant to endure through crisis, not float above it.
