Citing a diplomatic source in Washington, the newspaper said Kim mentioned the derogative nickname to Trump during their meeting in Singapore last month. Trump asked if he knew the song, and Kim replied that he didn't.

Pompeo said he plans to discuss denuclearisation as a follow-up to an agreement signed by Trump and Kim during their meeting last month.
"On this trip, I'm seeking to fill in some details on those commitments and continue the momentum toward implementation of what the two leaders promised each other and the world," said Pompeo in a statement cited by CBS News. "I expect that [North Korea] is ready to do the same."
