Former North Korea envoy says Trump approved signing pledge for Otto Warmbier's return

Former U.S. Special Representative for North Korea Joseph Yun told CNN Monday that he signed an agreement in 2017 to pay Kim Jong-un's regime $2 million for Otto Warmbier’s hospital care, a decision he believes was approved by President Trump.

The big picture: Trump has denied that the U.S. paid North Korea any money under the deal after the Washington Post reported its existence last week. National security adviser John Bolton confirmed on "Fox News Sunday" that an administration official did sign such a document.
