In a viral clip, the monarch appears to make a hand gesture as they turn the corner. She then attempts to pass behind the president, who stops walking and completely eclipses Queen Elizabeth from view for a moment. She returns to his right side and continues their walk.

Grant Harrold, a former butler for the royal family, told ITV News that letting the Queen lead in every scenario is a top rule in royal protocol.

Twitter users, including Alyssa Milano, called out the break in etiquette.

“This is disgraceful, @realDonaldTrump,” wrote the actress. “SHE’S THE QUEEN and she’s 92 years old! You’re incapable of acting like a human being. You’re incapable of being a leader.”

The Trumps were welcomed at the Quadrangle of the castle, where a Guard of Honor gave a royal salute and the U.S. national anthem was played. The Queen and President Trump inspected the Guard of Honor before watching the military march past. The president and first lady then joined the Queen inside the castle for afternoon tea.

Protesters marched through the streets of London — about 20 miles from Windsor Castle — against Trump’s U.K. visit on Friday.

Carrying signs that read “Trump Not Welcome” and “Dump Trump,” tens of thousands of British people took to the streets of central London to protest Trump in what was dubbed a “The Stop Trump March.”

Trump didn’t seem bothered when a crowd of protestors showed up to interrupt his golf game over the weekend by calling him racist.

While squeezing in a round of golf at the Trump Turnberry resort in Scotland on Saturday, the president was seen waving to a group of nearby protestors who were chanting, “No Trump, no KKK, no racist USA.”
