US, North Korean leaders to Singapore summit: Meet the key players

President Trump and North Korean leader Kim Jong Un are set to meet Tuesday for a historic summit in Singapore, the first of its kind between the current leaders of either nation.

The meeting between Trump and Kim is scheduled for 9 a.m. local time on Tuesday -- or 9 p.m. ET Monday. Both leaders are already in Singapore and are expected to meet first one-on-one, with the exception of translators, the White House has said. A bilateral meeting is scheduled for later, which will include, among others, Secretary of State Mike Pompeo, chief of staff John Kelly and National Security Adviser John Bolton.

North Korea has faced crippling diplomatic and economic sanctions as it has advanced development of its nuclear and ballistic missile programs.

Read on for a look at some of the key players of the summit.

After a sudden and welcome turn to diplomacy following last year's threats, insults and fears of war, Donald Trump and Kim Jong Un are ready to shake hands, sit down face-to-face and ... do what exactly? Whatever the results, it will be one of the more unusual summits in recent history as a flamboyant, often erratic U.S. president gets a close-up look at a hereditary socialist despot.
