King Charles III visit live updates: King and queen honor fallen soldiers at Arlington National Cemetery

Charles and Camilla started the final day of their U.S. state visit Thursday with a stop at the White House to say goodbye to President Donald Trump and first lady Melania Trump.

The two couples posed together and engaged in conversation outside the White House after spending much of the past three days together.

The Trumps hosted Charles and Camilla for a state dinner Tuesday night and greeted them earlier in the day with a ceremonial welcome at the White House.

On Monday, the two couples also spent time together at the White House, enjoying afternoon tea and inspecting the White House beehive.

After Charles and Camilla spent the day in New York City, one of the city’s most iconic landmarks paid tribute to the king and queen.

The Empire State Building lit up Wednesday night with the colors of red, white, blue and gold.

The colors were chosen, “in honor of Their Majesties King Charles III and Queen Camilla’s royal visit to New York,” according to a post on X.

The king and queen will spend most of the final day of their four-day state visit to the U.S. in the state of Virginia.

After a farewell meeting at the White House with President Donald Trump and first lady Melania Trump, Charles and Camilla will travel to Arlington National Cemetery, where they will lay a wreath at the Tomb of the Unknown Solider.

Charles and Camilla will then make the short trip to Virginia, where they will attend a block party for America’s 250th birthday celebration and visit both a national park and a horse-racing farm.

From there, the royals will board a flight to Bermuda, wrapping up a very busy four days.

The king and queen wrapped up their time in New York with a dinner at Christie’s in New York City for the Greater Together Reception which is held in partnership with the King's Trust.

Attending the dinner were cultural figures including Anna Wintour, Charlotte Tilbury, Donatella Versace, Edward Enninful, Iman, Karen Elson, Katherine Jenkins, Leo Woodall, Lionel Richie, Martha Stewart, Meghann Fahy, Nina Dobrev, Pat McGrath, Stella McCartney and Ralph Lauren, according to reporters who are traveling with the king and queen.

The King's Trust charity in America works with young people to develop employment training.

Ambassador Christian Turner, Lionel Richie and the king shared remarks at the event, according to a pool report.
