Kim Jong Un makes history, crosses border to meet his rival

GOYANG, Republic of Korea - With a single step over a weathered, cracked slab of concrete, North Korean leader Kim Jong Un made history Friday by crossing over the world's most heavily armed border to greet his rival, South Korean President Moon Jae-in, for talks on North Korea's nuclear weapons. Kim then invited Moon to cross briefly north with him before they returned to the southern side.
