'What is wrong with him?': MSNBC's Nicolle Wallace bursts into laughter over Trump's bizarre attempts at diplomacy

While the Singapore summit between President Donald Trump and North Korean leader Kim Jong-un has sparked a range of emotions, one moment, in particular, elicited a reaction from one MSNBC panel that you don't expect from nuclear weapons negotiations: outbursts of laughter.

On the show "Deadline: White House," host Nicolle Wallace could barely keep it together while listening to comments Trump made after the meeting about North Korea's real estate prospects.

"They have great beaches," Trump said of the autocratic regime. "You see that whenever they're exploding their cannons into the ocean, right? I said, 'Boy, look at that! Wouldn't that make a great condo!' And I explained, I said, you know, 'Instead of doing that, you could have the greatest hotels in the world.' Think of it from a real estate perspective!"

"I can't! Stop, come out," Wallace said to the control room. She was so stunned by the video — especially by the phrase "exploding the cannons" — that she had them play it again.

"So when they're testing their ICBMs, I'm thinking: 'What a spot! It could be like Boca!" she said. "What is that? What is wrong with him?"
