He will become the first British monarch to address the U.S. Congress since his mother, Queen Elizabeth II, in 1991. Her speech highlighted the shared history of both countries and the importance of their democratic values, themes Charles will likely reinforce on Tuesday.
Such addresses are an opportunity afforded to only the most prominent world leaders, including Pope Francis, Václav Havel and Winston Churchill. It will likely mark the most extensive public remarks Charles will deliver during a four-day visit to the U.S. that's intended to celebrate the country's 250th anniversary of independence from Britain.
House Speaker Mike Johnson, R-La., became the first sitting leader of his chamber to address the U.K. Parliament earlier this year. He attended a garden party with the king in Washington on Monday and said he told him he would be “well received” in Congress.
The king, accompanied by Queen Camilla, will begin his day with a meeting at the White House with President Donald Trump. The Oval Office encounter offers the potential for the freewheeling, sometimes controversial meetings with foreign leaders that have become routine during Trump's second term.
But given the expressly apolitical nature of the British monarch and Trump's fondness for the royal family, the likelihood of an awkward meeting may be reduced. Trump will host Charles on Tuesday evening for a state banquet at the White House.
The visit comes at a challenging moment for U.S.-U.K. relations. Trump’s up-and-down relationship with British Prime Minister Keir Starmer has taken a particularly sour turn over the past several months as the Republican president has sought to rally international support for the war in Iran. Trump criticized Starmer, who has largely resisted his overtures, by saying “this is not Winston Churchill that we're dealing with.”
