North Korean officials billed the U.S. $2 million for the medical care of comatose American Otto Warmbier before allowing him to be flown home from Pyongyang, the Washington Post reports. President Trump has previously denied that his administration has paid any sum of money for the release of U.S. hostages in the pariah state. According to the Post, State Department envoy Joseph Yun, who was in Pyongyang to take Warmbier home in June 2017 following news of his poor health condition, was instructed by North Korean officials to sign the agreement.
