Washington Times Opinion Editor Charlie Hurt has reacted to US President Joe Biden's latest gaffes while meeting King Charles III at Windsor Castle.

The 74-year-old monarch attempted to stop the 80-year-old from starting a conversation with a Welsh Guard. 

The President also appeared to breach Royal protocol after he grabbed the King by the arm and placed his hand on his back.

"You can't hide this from the public anymore. American voters see this. You can't lie to them and tell them this isn't happening." Mr Hurt told Fox News and Sky News Australia host Piers Morgan.
