WASHINGTON  (FOX NEWS) -- President Trump tweeted Thursday that his "highly anticipated meeting" with North Korean leader Kim Jong Un will take place in Singapore on June 12.

"The highly anticipated meeting between Kim Jong Un and myself will take place in Singapore on June 12th. We will both try to make it a very special moment for World Peace!" Trump tweeted on Thursday.

Trump is providing details for the first time about the history-making meeting between a sitting American president and the leader of North Korea over denuclearization.

He'd said he favored holding the meeting at the Demilitarized Zone, the heavily fortified border separating the Koreas. But the island nation was favored by most of his advisers.

Secretary of State Mike Pompeo traveled to Pyongyang twice to meet with Kim in recent months, in a precursor to the Trump-Kim meeting. Pompeo returned overnight with three captive Americans during his most recent trip.

Vice President Mike Pence is revealing new details about the conditions of the three Americans freed by North Korea, saying one was evidently kept from the daylight.

Pence tells ABC News that Secretary of State Pompeo told him that, during a refueling stop in Anchorage, "one of the detainees asked to go outside the plane because he hadn't seen daylight in a very long time."

Pence also told CBS he spoke Wednesday with the family of Otto Warmbier, an American detainee who died last year shortly after his release from North Korean captivity.

Pence said: "I simply let them know that while we received this news with joy, that Otto was on all our hearts and the family was in our prayers."

He adds: "We got Otto home the last year, but it wasn't soon enough."
