WASHINGTON (TNND) — King Charles III delivered a highly anticipated address to a joint session of Congress on Tuesday, marking a centerpiece moment in his first official visit to the United States as monarch.
The speech comes at a pivotal time for the transatlantic alliance, with political tensions and global conflicts testing the strength of the longstanding relationship between the United Kingdom and the United States.
Charles’s remarks place him among a small group of world leaders—and even fewer British royals—invited to address Congress. The moment carries deep symbolic weight, echoing Queen Elizabeth II’s 1991 speech and reinforcing the historic bonds between the two nations.
Charles began his address to Congress, referencing the Saturday night shooting at the White House Correspondents’ Dinner, calling it the “incident not far from this great building.” He said the shooting “sought to harm the leadership of your nation and to foment wider fear and discord.”
“Let me say with unshakeable resolve: such acts of violence will never succeed,” the King said. “Whatever our differences, whatever disagreements we may have, we stand united in our commitment to uphold democracy, to protect all our people from harm, and to salute the courage of those who daily risk their lives in the service of our countries.”
Saturday’s shooting took place just two days before King Charles and Queen Camilla were set to arrive in the US. The shooting briefly threatened to derail the plans for the four-day state visit. However, President Trump insisted that the royal couple would be “very safe” while in the US.
He also addressed Congress, beginning on a personal note by remembering his late mother, Queen Elizabeth II.
“Speaking in this renowned chamber of debate and deliberation, I cannot help but think of my late mother, Queen Elizabeth, who, in 1991, was also afforded this signal honor and similarly spoke under the watchful eye of the Statue of Freedom above us,” the King said during his address.
Charles then continued by praising US lawmakers. “So, I come here today with the highest respect for the United States Congress; this citadel of democracy created to represent the voice of all American people to advance sacred rights and freedoms,” the King said, later adding that today’s address is a “great occasion in the life of our Nations to express the highest regard and friendship of the British people to the people of the United States.”
He later used part of his speech to praise NATO and the role the defence alliance has played in protecting US citizens and interests. Charles specifically mentioned Sept. 11, 2001, as the first time that NATO invoked Article Five, which declares an attack on any one of the NATO alliance’s members is an attack on all.
His comments come after President Donald Trump has repeatedly criticized NATO for the lack of involvement in the conflict with Iran, leading to threats from Trump to withdraw the US from the organization entirely.
“The commitment and expertise of the United States Armed Forces and its allies lie at the heart of NATO, pledged to each other’s defence, protecting our citizens and interests, keeping North Americans and Europeans safe from our common adversaries,” Charles said.
Not only NATO conservation, but King Charles also brought a message of environmental conservation to Capitol Hill, urging American lawmakers that climate change is a matter of national security and a “shared responsibility.”
Charles, a longtime environmentalist and advocate for sustainability, told Congress, “we ignore at our peril” that nature provides “the foundation for our prosperity and our national security.”
“Our generation must decide how to address the collapse of critical natural systems, which threatens far more than the harmony and essential diversity of nature,” the monarch said.
This topic addresses a point of contention between the US and the UK; Trump’s “drill, baby, drill” philosophy is one that King Charles is against. While Charles is devoted to the use of wind farms, Trump dislikes them.
He concluded his address to Congress, reminding lawmakers that the US’ influence carries “weight and meaning.”
“Mr. Speaker, Mr. Vice President, distinguished ladies and gentlemen, America’s words carry weight and meaning, as they have since independence. The actions of this great nation matter even more,” the King said. “President Lincoln understood this so well, with his reflection in the magisterial Gettysburg Address that the world may little note what we say, but will never forget what we do.”
He then reaffirmed the relationship between the UK and the US as the latter marks its 250th birthday. “Let our two countries rededicate ourselves to each other in the selfless service of our peoples and of all the peoples of the world,” he said. “God bless the United States and the United Kingdom.”
The speech unfolds against a complicated political backdrop. Relations between President Donald Trump and British Prime Minister Keir Starmer have been strained, with disagreements over trade, tariffs, and foreign policy—including the war in Iran.
In early March, just days after the Iran war began, Trump seemingly derided Britain as “our once Great Ally” and told reporters, “This is not Winston Churchill that we’re dealing with.”
While the monarch remains constitutionally neutral, the address offers an opportunity for “soft diplomacy,” using tone and symbolism rather than policy to reinforce unity.
Charles and Queen Camilla arrived in Washington on Monday and had tea with Trump and First Lady Melania Trump.
Ahead of the address, the king and Camilla met with Trump again at the White House to participate in a ceremony on the South Lawn, with the president quipping that it was a “beautiful British day” under gray and dark skies.
Afterward, the two leaders had a closed-door meeting in the Oval Office. Trump said it was a “really good meeting,” and described Charles as a “fantastic person.”
Separately, Queen Camilla and the first lady spent part of Tuesday afternoon with America’s schoolchildren at the White House Tennis Pavilion.
The cross-cultural education program used artificial intelligence and virtual reality as part of Melania’s “Fostering the Future Together” initiative.
Later in the day, the Trumps will once again greet Charles and Camilla, beginning a series of events that include a tour and document viewing, a receiving line, and a private dinner at the White House.
The visit is part of a broader four-day trip to celebrate America’s 250th anniversary of independence from Britain, with additional stops in Virginia and New York.
Despite heightened security following a recent shooting at the White House Correspondents’ Dinner, events have continued as planned.
The address is widely seen as the defining moment of what some are calling a potential “royal reset” in U.S.–U.K. relations. By leaning into shared history and mutual interests, Charles is aiming to reinforce stability during a period of uncertainty.
