Let's start with John Bolton, in Seoul for high-stakes talks with officials here... there's a lot of chew over.
The U.S. National Security Advisor is currently in talks with his South Korean counterpart.
We are going to get the latest from our presidential correspondent Shin Se-min.

We are learning that John Bolton is already here at the top office for talks with his South Korean counterpart, Chung Eui-yong.
Prior to that,... we also know Bolton met with the floor leader of the main opposition Liberty Korea Party Na Kyung-won upon Na's request.
What we know is that the party leader strongly expressed how Japan's retaliatory trade restrictions against South Korea is damaging trilateral cooperation between Seoul, Washington and Tokyo one of the major talking points for the visiting U.S. official.
It's Bolton's first solo trip to Seoul perhaps indicating the gravity of the pending issues that would require such high-level U.S. consultation.
The ongoing trade spat between Seoul and Tokyo,... two of America's closest allies is one priority, but there is also the issue of the slow progress on the North Korea denuclearization drive.
South Korean officials will likely press the U.S. to step in on Japan's trade restrictions to South Korea,... a critical issue for the U.S.,... as the rift between the two Asian countries could jeopardize a number of issues.
With Seoul perhaps raising the possibility of ditching the General Security of Military Information Agreement, known as the GSOMIA with Tokyo,... that would deal a great blow to Washington's pursuit of beefier three-way security cooperation.
It's see as key to countering North Korean threats as well as checking China's growing military clout in the region.
The two may also hold consultations on the Strait of Hormuz as the U.S. is hoping to build a multinational force to safeguard commercial shipping in that area amid the tensions with Iran and its activities there in recent weeks.
And once the meeting at the top office wraps,... Bolton will hold separate talks with South Korea's defense chief and top diplomat before leaving Seoul at 4 PM.
We will have more on this as we learn the details, Mark?
