WASHINGTON — White House officials have cleared up some confusion over when CIA Director Mike Pompeo traveled to North Korea for a meeting with Kim Jong Un.

President Donald Trump tweeted Wednesday that the meeting took place “last week” and “went smoothly,” as preparations are underway for what would be a historic meeting between the U.S. and North Korean leaders.

Mike Pompeo met with Kim Jong Un in North Korea last week. 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!

Two White House officials, speaking on the condition of anonymity to discuss the sensitive discussions, confirmed that the trip took place over Easter weekend, and not last week as Trump had tweeted. Easter was on April 1.

Trump had disclosed on Tuesday that the U.S. and North Korea were holding direct talks at “extremely high levels” in preparation for a possible summit. Trump is huddling with Japanese Prime Minister Shinzo Abe at his private Florida club this week to assuage Japanese concerns about the meeting.
