U.S. President Donald Trump took his enthusiasm for his detente with North Korean leader Kim Jong Un to new heights on Saturday, declaring at a rally with supporters that “we fell in love” after exchanging letters, Reuters reported.

“I was really being tough - and so was he. And we would go back and forth,” Trump told a rally in West Virginia.

“And then we fell in love, okay? No, really - he wrote me beautiful letters, and they’re great letters,” he said.

His supporters laughed and applauded. Trump grumbled that commentators would cast him as “unpresidential” for describing Kim in such glowing terms.

The Trump administration is preparing for a second summit with Kim to talk about denuclearization. The time and location have not yet been announced.
