Security expert Victoria Coates says that Biden's trip to Europe exposed his frailty

Former Deputy National Security Advisor to former President Donald Trump, Victoria Coates, says that Biden's recent trip to Europe showed how fragile he is. 

"This isn't even a protocol issue, so much it is an exposure of the president's frailty," Coates said on the Tuesday edition of the "Just the News, No Noise" TV show. "He needed Charles to guide him. He needed a hand on someone, so he could get where he was going. And I thought the king handled it as gracefully as could be."

President Biden went to visit King Charles III in Europe to discuss climate change and the war in Ukraine. 

After Biden and Charles met, they took part in the Inspection of the Guard outside Windsor Castle, where Biden talked to a guard at the end of the line. 

Video footage shows Biden continuing to talk to the guard, despite Charles trying to lead him away. Eventually, Charles guided him away from the guard.

Coates also pointed out that it doesn't make sense for the president to discuss climate issues with the king of England. 

"I think ... the meeting was bizarre, because the topic was climate," Coates said. "And the whole point of it was the president was going to have kind of a special rapprochement with the king over the climate issue, in which they have a lot of common ground."

"This should not be a policy discussion," she said. "The king of England is a ceremonial head of state, not the policy person. So he should take it up with the prime minister and with the people who actually have political power in Great Britain."
