Otto Warmbier, an American student held captive in North Korea for 17 months, was released to U.S. officials the same day as Rodman's visit to North Korea. Despite the timeline of the two events, the U.S. State Department, The White House, and Rodman all flatly denied any diplomatic connection or coordination between Rodman's visit and the U.S. government. The U.S. State Department said the release of Warmbier was negotiated and secured by high level U.S. diplomats including Joseph Yun, the State Department's special envoy on North Korea. Warmbier, who was in a nonresponsive coma throughout much of his imprisonment in North Korea, died days after being returned to his family in the U.S.
