President Trump’s national security adviser said Sunday that he considered the summit with Kim Jong Un a “success,” despite it ending with no deal on denuclearization. Bolton also sought to clarify the president’s comments on Otto Warmbier, after Trump faced a backlash for saying he took Kim “at his word” when the dictator said he didn’t know of Warmbier’s treatment.
