In footage recorded during a reception at Buckingham Palace Tuesday, Canadian Prime Minister Justin Trudeau was seen standing in a huddle with French President Emmanuel Macron,
British Prime Minister Boris Johnson, Dutch Prime Minister Mark Rutte and Britain's Princess Anne, daughter of Queen Elizabeth II.
Trudeau could be heard saying "he was late because he takes a 40-minute press conference off the top" - an apparent reference to Trump's long unscheduled question session with journalists earlier Tuesday. Trudeau also said: "You just watched his team's jaws drop to the floor."
Trump wasn't mentioned by name.
