U.S. President Donald Trump on Wednesday confirmed CIA Director Mike Pompeo met with North Korean leader Kim Jong Un earlier this month ahead of a widely anticipated summit between the president and the dictator.

"Meeting went very smoothly and a good relationship was formed. Details of Summit are being worked out now. Denuclearization will be a great thing for World, but also for North Korea!" the president tweeted.

The meeting was first reported by the Washington Post.

The face-to-face meeting between Pompeo, who was recently nominated to be the new secretary of state, and Kim took place in North Korea over the Easter weekend and marks the highest-level sit-down between the two countries since 2000, the Washington Post said.

The purpose of Pompeo's confidential trip was to lay the groundwork for upcoming discussions between Trump and Kim, the Post reported, citing two unnamed sources.
