King Charles III addressed a joint session of Congress on the second day of his four-day visit to the United States, a trip timed to mark the 250th anniversary of the one-time British colony’s independence. His speech will come 35 years after his mother, Queen Elizabeth II, stood before both chambers of the U.S. legislature and, after joking that "I do hope you can see me," celebrated the shared democracies of the two nations. In their invitation to Charles to speak before Senators and Representatives, Congressional leaders described the relationship between the U.S. and the United Kingdom as "one of the most consequential partnerships in modern history."
