King Charles III is expected to address a joint session of the US Congress on Tuesday, telling lawmakers that "time and again, our two countries have always found ways to come together" while calling for "reconciliation and renewal" in the transatlantic alliance. The speech marks the first time a British monarch has addressed Congress since Queen Elizabeth II did so in 1991, coming during a state visit at what royal sources describe as a tense moment in US-UK relations.
The address is scheduled to last approximately 20 minutes and was written on advice from the UK government. Security in Washington DC has been heightened following an assassination attempt against President Donald Trump at a public event just two days before the visit began. The King is expected to express sympathy over that attack in his remarks, according to royal sources.
The monarch will tell Congress that in times of great international challenges, it is more necessary than ever to stand together to defend democratic values. He plans to urge support for beliefs of tolerance, liberty and equality, whether through supporting NATO or protecting Ukraine, the sources said.
What the Right Is Saying
Republican members of Congress greeted the state visit with enthusiasm for strengthening economic ties while expressing more cautious views on the alliance. Senator Ted Cruz, who attended a garden party at the UK Embassy, said the relationship remained "rock solid" despite recent tensions over Iran policy. He pointed to the recently completed tariff-free British beef agreement as evidence of productive bilateral trade negotiations.
The President's criticism of Prime Minister Sir Keir Starmer's response to the Iran conflict has created friction, but House Republican leaders suggested the state visit could help reset the tone. Representative Michael McCaul said monarchical diplomacy "operates at a different level than day-to-day political disagreements." The White House has not commented publicly on whether President Trump will address the same state dinner where King Charles is expected to speak.
What the Left Is Saying
House Democrats have largely welcomed the King's emphasis on multilateral institutions and collective defense. Representative Hakeem Jeffries, the House Democratic leader, said the speech would reinforce "the importance of our oldest and most reliable alliance." The remarks align with longstanding Democratic support for NATO and international cooperation that has characterized the party's foreign policy platform.
Progressive lawmakers noted the timing of the visit amid debates over US engagement in the Middle East. Senator Chris Murphy, who has been critical of increased military involvement in Iran, said he hoped the King's message would emphasize "diplomatic solutions over escalation." The speech's call for reconciliation was seen by some as a subtle push for continued dialogue between Washington and Tehran.
What the Numbers Show
King Charles becomes only the second British monarch to address a joint meeting of Congress, following Queen Elizabeth II in 1991. That speech lasted approximately 35 minutes and focused on Cold War relations and the Gulf War. The current visit marks the first state visit by a British monarch since Queen Elizabeth's seven-day tour in 2007.
The US-UK trade relationship totals approximately $300 billion annually, making it one of the largest bilateral trading partnerships in the world. The recently negotiated tariff-free quota for UK beef imports represents the first such deal following decades of restrictions related to BSE concerns. President Trump has imposed tariffs on multiple countries since taking office but granted the UK an exemption on certain agricultural products as part of ongoing trade discussions.
The Bottom Line
The state visit proceeds at a complicated moment in US-UK relations, with the Iran policy disagreement representing one of the most significant splits between the allies in recent memory. King Charles's speech will attempt to emphasize continuity and shared values while carefully avoiding direct reference to current political disputes. Whether a monarch can bridge a gap that has frustrated even career diplomats remains to be seen, but Buckingham Palace is treating this as a long-term investment in institutional ties rather than an immediate fix. The White House state dinner later Tuesday will bring together politicians and celebrities from both nations for what officials describe as the centerpiece of the four-day visit.
