Prince Charles Will Meet President Obama in the White House in March

Fresh off his visit with Prince William last year, Obama is going to host another royal guest — the heir to the British throne.

Charles, Prince of Wales, and Camilla, Duchess of Cornwall, are scheduled to meet with Obama during their four-day visit to the United States in March.

The heir to the throne will meet with the President in the Oval Office on March 19, according to a tweet from the National Security Council, and the meeting is said to underscore the “special relationship” between the U.S. and the U.K.

The royal pair will be visiting during the 150th anniversary of the end of the Civil War and Lincoln’s death, and are planning to visit numerous historical sites, including the home where Lincoln is thought to have written the last draft of the Emancipation Proclamation, according to a news release. They’ll also visit Mount Vernon and meet with American veterans, and stop off in Louisville, KY.
