President Donald Trump’s patio strategy session at Mar-a-Lago on Saturday evening is drawing scrutiny for its open-air nature, including aides’ use of cell phone flashlights to illuminate potentially sensitive documents.

As Trump discussed a response to North Korea’s missile test with Japanese Prime Minister Shinzo Abe, other diners looked on freely.

Sources who don’t work in national security or government but were also dining on the patio Saturday evening couldn’t say whether the conversations or documents were classified. The White House didn’t respond to a request for information about how sensitive information is treated at Trump’s Florida estate.

But the episode — which was documented by diners in photographs on Facebook — does raise questions about how the Trump administration will handle foreign policy crises on the road.
