Some prominent Americans who have met with North Korean leaders

Trump has agreed to meet with Kim Jong Un.

No sitting U.S. president has ever met with a North Korean leader, though there have been lower-level sessions.

Carter met with Kim Il Sung, North Korea's founder, in 1994, more than a decade after leaving office.

Kim Il Sung, who died weeks after meeting with Carter, is the grandfather of current leader Kim Jong Un.

Instead, then-Secretary of State Madeline Albright went to North Korea.

That wasn't the last time that a former president met with North Korean officials to help free an American. In 2010, Carter returned to North Korea on behalf of Aijalon Gomes, a Massachusetts resident who was sentenced to eight years of hard labor for entering the country illegally.

Carter returned to the so-called hermit kingdom in 2011, this time along with other world leaders as part of talks about the country's food shortage.

Rodman visited the country in 2014 and once again in 2017.

He met with Kim Jong Un on both visits.
