King Charles III is preparing for a landmark moment in Washington Tuesday, becoming the first British royal to speak before the United States Congress in more than three decades as he works to strengthen diplomatic ties between two historic allies.
The monarch will follow in the footsteps of his late mother, Queen Elizabeth II, who last addressed lawmakers in 1991 with remarks focused on shared democratic principles and common heritage between the nations. Charles is expected to echo similar themes during what will likely be his most significant public remarks of a four-day American tour celebrating the country’s upcoming 250th independence anniversary.
This rare congressional appearance places Charles among an exclusive group of world figures granted such an honor, joining the ranks of Pope Francis, former Czechoslovakian President Václav Havel, and wartime British Prime Minister Winston Churchill.
House Speaker Mike Johnson made history himself earlier this year as the first sitting House leader to address Britain’s Parliament. After attending a Washington garden party with the king Monday, Johnson assured Charles he would receive a warm congressional welcome.
The royal visit begins Tuesday morning with an Oval Office meeting between Charles, Queen Camilla, and President Donald Trump. Despite Trump’s sometimes unpredictable diplomatic style, the encounter may prove less contentious given the traditionally nonpartisan role of British royalty and Trump’s well-documented appreciation for the royal family. Trump will cap the day by hosting Charles at a formal White House state dinner.
However, the visit unfolds amid strained relations between Washington and London. Trump’s relationship with British Prime Minister Keir Starmer has deteriorated significantly as the president seeks international backing for military action in Iran. Trump has openly criticized Starmer’s reluctance to provide support, stating “this is not Winston Churchill that we’re dealing with.”
Economic tensions have also emerged, with Trump implementing tariffs on British goods and threatening additional trade penalties despite a recent Supreme Court decision limiting such unilateral actions. Just last week, Trump warned of imposing substantial tariffs unless Britain eliminates its digital services tax affecting American technology companies.
Trump’s broader foreign policy approach has challenged traditional Atlantic partnerships through attempts to acquire Greenland and repeated threats to withdraw from NATO. He has also targeted Canada, a Commonwealth nation, with both tariffs and public criticism.
The royal visit has drawn some controversy on Capitol Hill, with certain lawmakers calling for Charles to meet with Jeffrey Epstein victims during his stay. No such meetings are planned, despite ongoing scandal surrounding the convicted sex offender that has implicated the king’s brother, who was arrested in February on misconduct charges he denies.
California Representative Ro Khanna urged Charles over the weekend to address the Epstein matter during his congressional address.
House Democratic Leader Hakeem Jeffries criticized Republican policies Monday for damaging the Anglo-American relationship. “Hopefully, the king’s visit is going to go a long way toward repairing the damage that this administration has done to one of our most important allies in the world,” Jeffries said.
Charles and Camilla arrived in the nation’s capital Monday for tea with President Trump and First Lady Melania Trump. Their American tour continues later this week with scheduled visits to New York City and Virginia.
