South Korean President Moon Jae-in has arrived in the United States to meet President Donald Trump.

The leaders are expected to discuss the DPRK's denuclearization and the upcoming US-DPRK summit on June 12th. Reports say Moon is scheduled to speak over the phone with DPRK leader Kim Jong Un after his Washington trip. Pyongyang last week shocked both South Korea and the US by breaking off a high-level meeting with Seoul, and also threw into doubt the summit with Trump if Pyongyang was pushed toward "unilateral nuclear abandonment". Our correspondent Jack Barton has the details.
