North Korea Summit Remains On Shaky Ground
An unprecedented U.S.-North Korea summit is supposed to take place in three weeks.
President Donald Trump will meet South Korean President Moon Jae-in on Tuesday as U.S. officials try to figure out whether North Korea is serious about negotiating a deal on denuclearization.
Last week North Korea threatened to pull out of the planned June 12 summit in Singapore and condemned the latest U.S.-South Korean air combat drills.
Trump has insisted he remains committed to the summit.
