Trump broke the news on Tuesday at the White House as he announced the US is withdrawing from the Iran nuclear deal.
Trump said Pompeo has meetings set up in North Korea and should be landing in an hour.
“The location is picked, the time and date, everything is picked and we look forward to having a great success,” he said of the upcoming summit.
Asked whether Pompeo would return with the three American prisoners currently held in North Korea, Trump played coy.
“We’ll all soon be finding out,” he said. “It would be a great thing if they are.”
Pompeo previously traveled to North Korea over the Easter weekend, where he met with the North Korean leader.
