President Donald Trump. Getty A paying member of President Donald Trump's Mar-a-Lago resort in Palm Beach, Florida, took photos of the moment Trump and Japanese Prime Minister Shinzo Abe were surrounded by Trump aides during dinner to be briefed on North Korea's missile test on Saturday.

The meeting was conducted in the open, in front of members of the club, with cellphone lights pointing toward sensitive documents. The decision-making about responding to North Korea was "on full view to fellow diners," CNN reported.

"Trump's National Security Adviser Michael Flynn and Chief Strategist Steve Bannon left their seats to huddle closer to Trump as documents were produced and phone calls were placed to officials in Washington and Tokyo," according to CNN. "The patio was lit only with candles and moonlight, so aides used the camera lights on their phones to help the stone-faced Trump and Abe read through the documents."

John Cook, a journalist, said that it was likely unsafe to be pointing phones, whose cameras and microphones can be hacked, at sensitive documents, tweeting on Sunday, "We used to put our phones in fridges to talk about Snowden docs at The Intercept. These ... are POINTING THEIR PHONES at class[ified] info."

It is unclear if Trump had his unsecured Android phone with him during the briefing, which he still carries around with him to send tweets, according to The New York Times. The unsecured phone is susceptible to phishing attacks that could infect the phone with malware, which is capable of taking over the phone's camera and microphone.

Richard DeAgazio, a retired investor and member of Mar-a-Lago, took photos of the scene and posted them on his Facebook page, which he has since deleted.

"HOLY MOLY !!!" DeAgazio wrote in a caption for another photo. "It was fascinating to watch the flurry of activity at dinner when the news came that North Korea had launched a missile in the direction of Japan. The Prime Minister Abe of Japan huddles with his staff and the president is on the phone with Washington DC. The two world leaders then conferred and then went into another room for hastily arranged press conference. Wow.....the center of the action!!!"

Reached by The Washington Post on Monday, DeAgazio said the fact that Trump chose to stay outside for his meeting with Abe, "with the members," shows "he's a man of the people." DeAgazio insisted, however, that he couldn't hear anything that was discussed between the leaders and their aides.

DeAgazio also posted a photo of himself with a US official whom he identified as being responsible for carrying the "nuclear football" — a briefcase whose contents can be used by the president to authorize a nuclear strike.

The journalist Sam Oakford first spotted the photos on DeAgazio's Facebook page.

DeAgazio also took a photo with Trump's chief strategist, Steve Bannon.

Mar-a-Lago's membership fee doubled to $200,000 on January 1. The initiation fee had been $200,000 until 2012, when it was cut to $100,000 after the Bernie Madoff scandal. To retain access to the resort, members must also pay $14,000 in yearly dues and contribute an additional $2,000 a year for food, according to ABC.
