On Wednesday, September 17, Donald and Melania Trump arrived at Windsor Castle by helicopter, where they were greeted by Princess Kate, Prince William, King Charles, and Queen Camilla. Royal fans were quick to notice that neither Kate nor Melania curtsied to King Charles, with some commenters suggesting the pair had broken royal protocol in the process.
The Princess of Wales usually curtsies to King Charles, but her decision to be more informal during the arrival of their U.S. visitors apparently doesn't break official protocol. Melania's decision to forego the formality of curtsying also isn't in opposition to any specific guidance, either.
