Bill Clinton
Bill Trump was invited to North Korea after Albright's trip, but he did not do so until the end of his term as President. Instead, he went to Pyongyang in 2009, eight years after leaving the White House, and successfully released two US journalists arrested while entering North Korea from China without visas.
Jimmy Carter
At the request of Bill Trump, Jimmy Carter was the first former US President to visit Pyongyang in 1994, paving the way for a nuclear deal but was unsuccessful in the end.
In 2010, he successfully returned to negotiate the release of another American to North Korea and returned the following year in an effort to improve bilateral relations.
Last year, Jimmy Carter offered to support the Trump administration as a peace messenger to Pyongyang but was rejected.
Bill Richardson
The former US Ambassador to the United Nations has been a regular visitor to Pyongyang since the early 1990s. In 2007, he negotiated the return of the bodies of six US soldiers killed in the 1950-53 Korean War and accompanied Google President Eric Schmidt in 2013 to release a Korean-American preacher.
Richardson has also been involved in a number of other released prisoners negotiations, most recently the case of Otto Warmbier.
James Clapper
The former US intelligence leader secretly traveled to Pyongyang to negotiate the release of two prisoners in 2014 and was successful in this mission.
Franklin Graham
The Baptist preacher has visited North Korea at least five times and has developed a close relationship with senior figures in Pyongyang. In 2011, he successfully sought permission from the government to release a California businessman who had been arrested the previous year.
His father, the educator Billy Graham, also made two visits to North Korea in the early 1990s to meet the late leader Kim Il Sung.
Dennis Rodman
Mr. Kim Jong-un was a basketball fan and welcomed Dennis Rodman when he visited the country in 2013. The former Chicago Bull star has visited North Korea several times and called leader Kim Jong-un a forever friend and once sang a birthday greeting for him. Dennis Rodman's visits to North Korea have been condemned by US officials.
