He said this was again a "subtle gesture" from Trump to gain sympathy, with gentle touches to the North Korean's shoulder and back.
However, it now appears that the U.S.is confident tings are going smoothly. He can't do that.
While President Trump has spoken positively about the upcoming summit, he has been vague on details of what they might be able to actually achieve.
There was no word on how Trump was spending the night before the summit.
The summit is not expected to last beyond Tuesday, with both leaders set to leave Singapore shortly after concluding their meetings.
"When I got home (from North Korea in 2014), I got so many death threats". In that way, the summit has already been a victory for Kim even if no agreement is reached.

Professor John Hajek from the University of Melbourne's School of Languages and Linguistics said the US President was "doing all the talking" and had the "upper hand" when the two met for their historic meeting.
The summit is scheduled to begin at 9am, the White House said.
Rodman said Kim, who was educated in Switzerland, "understands bits and pieces" of English.
AP media relations director Lauren Easton said that the outlet was "troubled" by the press' limited access to some of the events. They will be joined only by translators and will spend a couple of hours before admitting their close advisers to the meeting.More news: E3 2018: BioWare Anthem launch date set for February 22, 2019
