US President Donald Trump has arrived at the Capella Hotel on Sentosa Island for his historic meeting with North Korean leader Kim Jong-un.
Trump says his historic summit with the North Korean leader Kim Jong-un could "work out very nicely" as officials from both countries sought to narrow differences on how to end a nuclear stand-off on the Korean peninsula.
Shortly before leaving his hotel for the summit, President Trump said the "haters & losers" were complaining that his meeting with North Korea's Kim Jong Un was a "major loss," but noted the US had its three captives returned and the North's nuclear missile launches had stopped.
Trump tweeted early on Tuesday from Singapore, just hours before his face-to-face with Kim.
He said:"The fact that I am having a meeting is a major loss for the U.S., say the haters & losers." But he said "our hostages" were back home and testing, research and launches had stopped.
He said: "These pundits, who have called me wrong from the beginning, have nothing else they can say!"
Critics have argued that Kim has notched a win by getting a sit-down with the US president.
President Trump will sit down with Fox News host Sean Hannity after his summit with the North Korean leader.
Fox News says the interview will take place at the Capella Hotel, the venure for the summit.
Trump and Kim are set to meet on Sentosa Island on Tuesday morning for roughly 45 minutes while their entourages wait nearby.
Hannity is a friend and confidant of the president and speaks out in support of Trump on his show.
