“They have great beaches,” Trump told reporters during the summit in Singapore on Tuesday. “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, laughing at the clip while asking the control room to stop the video. After addressing her panel, she asked for the president’s “exploding the cannons” remark to be played again.

"So when they're testing their ICBMs, I'm thinking: 'What a spot! It could be like Boca!" Wallace remarked, referring to the Boca Raton vacation spot in Florida.

"What is that? What is wrong with him?" she said.

Wallace, who served in former President George W. Bush's White House, has repeatedly scrutinized Trump's moves as president.

Earlier this year, she questioned why women serving in the White House don't "walk out en masse" following controversy over the administration's handling of past abuse allegations against a staffer and she called some of Trump's tweets "boldface lies" while reading them on-air last month.
