"Trump clearly has the upper hand here because the media in North Korea is so tightly controlled". In May, North Korean state media said of Mr. Bolton: "We do not hide our feeling of repugnance towards him".
It's the first ever meeting between a sitting US president and North Korean leader.
"She called me and said, 'Dennis, Donald Trump is so proud of you".
"We're going to take care of a very big and very risky problem for the world", Trump said. "We will have a terrific relationship".
For his part, Trump appeared exceedingly optimistic about the ongoing talks.
He said on Thursday that he didn't think he had to prepare very much for the summit and that "it's about attitude".
Trump made the comments as he and Kim walked together along balcony as they headed to a larger meeting with aides.
"For long-time Korea-watchers, seeing the first-ever handshake and meeting between a sitting US president and North Korean leader is already momentous".
He reiterated that the goal of the summit remains the same: "the complete, and verifiable, and irreversible denuclearization of the Korean Peninsula". "I mean, what world is that we're living in?" "And it's my honor to be involved".
Just hours ahead of the crunch talks, Kim left his luxury hotel for a night-time stroll around some of Singapore's main sights, even posing for selfies with his guide, the city-state's foreign minister. When I said those things, when I went back home, I got so many death threats ... and I believed in North Korea, and I couldn't even go home, I couldn't even go home, I had to hide out for 30 days, I couldn't even go home.
The stakes are high, although Trump himself sought to lower expectations for a breakthrough nuclear deal, stressing the meeting was the start of a process that would set the stage for further negotiations.
Prior to the Singapore summit, President Trump had stressed the importance of first impressions at the meeting.
During another photo-op before the two leaders began a working lunch, no independent journalists were allowed into the pool.
"It's my honor. We will have a terrific relationship", the president told reporters as he and Kim sat across from one another moments after the historic handshake on a stage bedecked with United States and North Korean flags".
The number of American journalists allowed to witness the one-on-one meeting between President Donald Trump and Kim Jong Un in Singapore on Tuesday was limited to seven - a smaller group than would usually be present for such a summit, and one that excluded representatives from the major wire services. "The US position remains clear and unchanged".
