Ex-NBA star Dennis Rodman has left North Korea after his unexpected round of basketball diplomacy. At the airport, he called leader Kim Jong Un an "awesome guy" and said his father and grandfather were "great leaders."

Rodman is the highest-profile American to meet Kim since the authoritarian leader inherited power from his father, Kim Jong Il, in 2011. Kim and Rodman watched a basketball game Thursday and later drank and dined on sushi together.

At Pyongyang's Sunan airport on Friday, Rodman said it was "amazing" that Kim "was so honest." He added that Kim Jong Il and North Korean founder Kim Il Sung "were great leaders."
