King Charles met with congressional leaders earlier Tuesday.
King Charles III and Queen Camilla are making their first-ever state visit to the U.S., visiting Washington, D.C., New York City and Virginia.
The royals’ visit comes amid significant strains between the U.K. and the U.S. over the war in Iran. It’s also happening under the shadow of Charles' brother Andrew Mountbatten-Windsor's connection to the ongoing Epstein scandal.
The king and queen were feted at the White House on Tuesday with a traditional military arrival ceremony and a state dinner. Charles also delivered a rare joint address to Congress, where he emphasized the historic partnership between the U.S. and U.K. and praised NATO.
King Charles and Queen Camilla have arrived at the South Portico of the White House for a formal state arrival ceremony. They are being greeted by President Donald Trump and first lady Melania Trump.
Notable officials are gathered on the White House South Lawn in rainy weather for the ceremony that will include a review of the troops, remarks by Trump and more.
President Trump is hosting King Charles III and Queen Camilla at the White House as the "special relationship" between the United States and the United Kingdom is under a microscope amid the war with Iran.
While Trump has repeatedly praised King Charles as a "friend" whom he's known for years, his relationship with U.K. Prime Minister Keir Starmer has been another story. The president has repeatedly assailed the U.K. and other NATO allies over the U.S. and Israeli war with Iran.
Trump said the visit from the king -- the U.K.'s constitutional and ceremonial head of state -- may help restore any damaged ties between the two allies.
"Absolutely. He's fantastic. He's a fantastic man. Absolutely the answer is yes," Trump told the BBC in a phone interview when asked if the visit could help repair the relationship.

President Donald Trump and first lady Melania Trump will welcome Great Britain’s King Charles III and Queen Camilla to the White House South Lawn later this morning.
Thousands of guests are anticipated to be in attendance, including Cabinet officials, U.S. and U.K. delegations, members of Congress, students from the British International School of Washington and more.
The official arrival of the king and queen will begin with a traditional military arrival ceremony by the U.S. Army Herald Trumpets, a "tradition that dates back to the 18th century," the first lady’s office said. The national anthems of both countries will then be played by the U.S. Marine Band, followed by the Presidential Salute Battery rendering a 21-gun cannon salute.
"Following an Inspection of the Troops and a Troop in Review, facilitated by the U.S. Army Fife and Drum Corps, the President will deliver remarks from the South Lawn," the first lady's office said in a press release.

Charles and Camilla were shown the White House beehive by President Donald Trump and first lady Melania Trump during their visit Monday.
Videos shared on social media by a top White House aide show the president and first lady and the king and queen inspecting a new White House-shaped beehive that is part of an expansion announced by the first lady last week.
Two other beehives have been on the south grounds of the White House since 2009, according to The Associated Press.
