WASHINGTON (Reuters) - The United States signed a document agreeing to pay North Korea for the care of American Otto Warmbier but never paid the $2 million (1.5 million pounds) Pyongyang demanded, White House national security adviser John Bolton said on Sunday.

Bolton, who said he was not part of the administration at the time, confirmed newspaper reports that North Korea demanded the money before Warmbier was flown out of Pyongyang in a coma on June 13, 2017.
