A cloud of uncertainty continues to hover over Trump's meeting with Kim in Singapore as North Korea on Tuesday abruptly threatened to pull out of the planned June 12 summit, blaming USA demands for "unilateral nuclear abandonment". In August, Bolton defended the idea of a preventive military strike against the North, and last month suggested negotiations in 2004 that led to the shipping of nuclear components to the US from Libya under Moammar Gadhafi would be a good model for North Korea as well. "In Libya we decimated that country, that country was decimated, there was no deal to keep Gaddafi", he said.
The governors' letter came amid reports from South Korea's Yonhap News Agency that North Korea was canceling a high-level meeting planned between the two countries due to the ongoing military exercises between the US and South Korea.
The threatened cancellation of the summit, the first between United States and North Korean leaders, would deal a major blow to what could be the biggest diplomatic achievement of Mr Trump's presidency.
In his statement Tuesday, Kim Gye Gwan, North Korea's first vice foreign minister, said of Bolton: "We do not hide our feeling of repugnance towards him". To mark the anniversary, Trump lawyer Rudy Giuliani sought to steer the media narrative by saying Mueller's team concluded they can not indict a sitting president.
Mr Trump has yet to be interviewed, though it is understood that Mr Mueller's team has spoken to the president's lawyers about a possible interview and the scope of any testimony that might take place.
"The Libyan model was a much different model".
An end to US and South Korean military exercises and sanctions on the North, trade and investment, USA recognition of his regime, a peace treaty, and the eventual removal of USA bases and troops. "His country would be very rich", Trump explained. We'll see what happens.
The US president also suggested China was influencing North Korea's thinking regarding the summit, pointing to Kim's visit to China immediately before secretary of state Mike Pompeo visited Pyongyang last week to finalise the summit date and location.
Yet, thanks to Trump's threats and refusal to accept a "frozen conflict" on the Korean peninsula, the makings of a real deal are present, if Trump does not make the ideal the enemy of the good.
At his meeting with Xi, the leader of the North Korean delegation, Pak Thae Song, said he had been entrusted with consolidating recent agreements between Kim and Xi as well as studying China's model of economic development and "reform and opening".
Trump, who was scheduled to meet the top leader of North Korea on June 12, however, also cautioned that the Libya model could take place if "we do not most likely make a deal", Xinhua news agency reported.
Mr Trump said he is "willing to do a lot" to provide security guarantees to Kim.
Mr Trump told reporters that if the meeting happens then "it happens" and if not the United States will go on to the next thing.
Moreover, while we are running a risk today, an intransigent North Korea that walks out would be running a risk as well. "Perhaps he doesn't want to do it".
He was castigated by the North for trying "to force our unilateral nuclear abandonment", and the country threatened to walk away from the summit in Singapore.
The U.S. has said that North Korea must take concrete steps toward denuclearization before any sanctions can be relaxed.
