April 29 (UPI) -- U.S. President Donald Trump and first lady Melania Trump hosted King Charles III and Queen Camilla at a state dinner at the White House on Tuesday, where both leaders praised the U.S.-British relationship and pledged to strengthen the alliance.

In the East Room of the White House, Trump described the king's state visit to the White House as "historic," occurring as they prepare to celebrate the United States' 250th year of independence.

"It is only natural that Americans begin this by paying tribute to the transcendent bond we share with the nation that Thomas Jefferson himself called our mother country," Trump said.

"Tonight, on the eve of our 250th year of cherished independence, we turn to the sovereign embodiment of our British heritage and say, sincerely, thank you to our friends, the United Kingdom, for the richest inheritance that any nation has ever given to another."

He complimented the "fantastic speech" Charles had given only a few hours earlier before a joint meeting of Congress, joking that the king was able to garner a standing ovation from the Democrats.
