I suppose it was Trump, the TV personality mugged the camera and actually had the queen follow him down the review line. You can tell it was a breach of protocol and the queens discomfort and at a loss, this queen who has probably been confronted with every single type of breach of protocol there is over her lifetime, but then came The Donald. How dare he come between the camera and the queen.
The only thing funnier could have been Trump photo bombing the queens photo shots.
If you had watched the whole video before blathering nonsense, you would have seen that President Trump did exactly what the Queen gestured for him to do. She indicated he should go where he did and also orchestrated where the royal guard should go.
President Trump followed what she wanted him to do, then waited for her. She NEVER followed him down the review line - she led all the way.
You should have looked closer. The Queen motioned 2-3 times for Trump to go ahead of her.
