President Trump meets at the White House Tuesday with South Korean President Moon Jae-in. The two men are partners in an effort to strip North Korea of its nuclear weapons.
The meeting is a chance for Trump and Moon to strategize before a planned summit next month in Singapore with North Korean leader Kim Jong Un.
That meeting has been called into question, after North Korea suggested it's not willing to give up its nuclear weapons. For now, the U.S. and South Korea are proceeding on the assumption the meeting will take place.
