Charles and Camilla’s first stop in New York City Wednesday was the National 9/11 Memorial, where they met with families of Sept. 11, 2001, victims and first responders.

The royals were greeted by former New York City mayor Michael Bloomberg, who showed them the memorial and stood by their side as they laid a bouquet of flowers.

The flowers were accompanied by a note that read, “We honour the memory of all those who so tragically lost their lives on 11th September 2001, and stand in enduring solidarity with the American people in the face of such profound loss. Charles R Camilla R," according to reporters who are traveling with the king and queen.

Other elected officials in attendance at the memorial were New York City Mayor Zohran Mamdani, New York Gov. Kathy Hochul and New Jersey Gov. Mikie Sherrill.

King Charles’ toast at Tuesday night's White House state dinner included quips, sympathies and a special gift for President Donald Trump.

Charles delivered the toast in front of the president and first lady Melania Trump, Queen Camilla and a room full of attendees that included U.S. Supreme Court justices, elected officials, CEOs and professional golfer Rory Mcllory.

Charles and Camilla are heading to New York City Wednesday for a full day of events on the third day of their closely watched state visit to the United States.

The royal couple’s first stop will be the National 9/11 Memorial, where they will meet with families of Sept. 11, 2001, victims and first responders, as well as elected officials including New York City Mayor Zohran Mamdani, New York Gov. Kathy Hochul and New Jersey Gov. Mikie Sherrill.

From there, the king will visit an after-school urban farming program while the queen holds a reading reception at the New York Public Library.

Later in the day, Charles will attend a trade and business leader event followed by a King's Trust reception in the evening to highlight the U.K.’s cultural impact on New York, according to Buckingham Palace.

Charles and Camilla will return to Washington D.C., Wednesday night.

President Donald Trump and first lady Melania Trump welcomed King Charles III and Queen Camilla back to the White House Tuesday evening for a state dinner in the East Room.

Trump opened the dinner by lavishing praise on the royal and joking about the bipartisan reception King Charles III received during his address to Congress earlier Tuesday.

"He got Democrats to stand, I've never been able to do that. I couldn't believe it," Trump joked.

Trump also remarked about the long history of the U.S. and the U.K., calling it a "very, very special and incredible friendship."

King Charles III began his toast by reflecting on the shooting at the White House Correspondents' Association Dinner on Saturday, "paying tribute to your own courage and steadfastness, as well as to your security services for their swift actions on Saturday evening in preventing further injury," the king told Trump. "My thoughts and sympathies are very much with you, the first lady and all those guests for whom this must have been a very upsetting incident."

There were light-hearted moments in the king's toast as well.

The king referenced Trump's decision to tear down the East Wing to build a White House ballroom, making a joke referencing the burning down of the White House during the War of 1812.

"On this occasion, I cannot help noticing the readjustments to the East Wing, Mr. President, following your visit to Windsor Castle last year," the king said. "And I'm sorry to say that we British, of course, made our own small attempt at real estate redevelopment of the White House in 1814."

Towards the end of his remarks, King Charles presented the president with the bell from HMS Trump, a British ship during World War II.
