WATFORD, England (AP) – Several NATO leaders have been caught in an unguarded exchange on camera apparently gossiping about U.S. President Donald Trump’s behavior. Footage was recorded during a reception at Buckingham Palace with the leaders of Canada, France, Britain and the Netherlands standing in a huddle with a British royal. Trump wasn’t mentioned by name during the exchange, but they appeared to be talking about Trump’s unscheduled question-and-answer session with journalists.
