On Tuesday, April 28, 2026, King Charles III delivered a speech to the U.S. Congress that starkly contrasted with policies and rhetoric associated with former President Donald Trump.

During his address, Charles highlighted the Magna Carta—a foundational legal document signed by England’s King John in 1215—as a cornerstone of U.S. law, particularly in limiting executive power. “The U.S. Supreme Court Historical Society has calculated that Magna Carta is cited in at least 160 Supreme Court cases since 1789, not least as the foundation of the principle that executive power is subject to checks and balances,” he stated.

The king’s remarks drew an immediate standing ovation from Democrats, while Republicans offered delayed applause. His comments appeared to directly reference Trump’s efforts to expand presidential authority and disregard congressional oversight, often with the support of conservative justices on the Supreme Court.

Charles also emphasized the role of Christianity in fostering interfaith solidarity, a concept notably absent from Trump’s rhetoric. “The Christian faith is a firm anchor and daily inspiration that guides us not only personally—” he began, before pausing for applause. He continued, “Guides us not only personally, but together as members of our community.”

He added, “Having devoted a large part of my life to interfaith relationships and greater understanding, it is that faith in the triumph of light over darkness, which I have found confirmed countless times. Through it, I am inspired by the profound respect that develops as people of different faiths grow in their understanding of each other.”

Charles’s strongest applause came when he underscored the importance of NATO, a stance Trump has publicly opposed. The king referenced the alliance’s collective defense under Article 5 following the 9/11 attacks and its continued necessity in supporting Ukraine. “In the immediate aftermath of 9/11, when NATO invoked Article 5 for the first time, and the United Nations Security Council was united in the face of terror, we answered the call together, as our people have done so for more than a century, shoulder to shoulder, through two world wars, the Cold War, Afghanistan, and moments that have defined our shared security,” he said. “Today, Mr. Speaker, that same unyielding resolve is needed for the defense of Ukraine and her most courageous people.”
