Royal fans have spotted one major clue that shows King Charles "won't be pushed around" by US President Donald Trump. The King and the American President were reunited on Monday, seven months after his State Visit to the UK last year.

Pictured shortly after the King and Queen touched down in Washington, D.C., a video captured shows President Trump going in for a handshake with the King, whilst their wives greeted each other with a kiss.

Fans appeared to notice that Trump forcefully held onto the King's hand, whilst the monarch appeared reluctant to offer such a firm handshake.

Taking to X, one fan, alongside the video, wrote: "Trump is trying his toxic beta-male handshake, and Charles is having absolutely none of it."

A second added: "Trump tried, Charles said nope! [wide-smile emoji]."

The comments underneath the video then showed a host of videos of Trump shaking hands with a range of political figures - who also had a similar reaction to the King.

One fan commented: "Donald Trump has done it to Emmanuel Macron a few times, Trump can't contain his anger and contempt."

Shortly after their arrival, the couple were met by the sounds of the National Anthem - with fans taking to X to share one major thing they noticed. The couple were spotted standing behind a blacked-out vehicle, which blocked their view.

One fan wrote on X: "Why on earth is there a car blocking the view of the King and Queen during the national anthems? Bizarre American protocol faux pas at roughly the 2-minute mark of the trip."

To mark the end of their first day in the US, the King and Queen were joined by 650 guests at a lavish garden party in Washington DC.
