Trump's surprise reversal Friday marks a departure from his administration's messaging a day earlier. In a tweet Thursday after the Treasury's announcement, White House National Security Advisor John Bolton said "everyone should take notice and review their own activities to ensure that they are not involved in North Korea's sanctions evasion."
In explaining the president's sudden announcement, White House press secretary Sarah Huckabee Sanders said, "President Trump likes Chairman Kim and he doesn't think these sanctions will be necessary." Trump's tweet and the press secretary's clarification of it sent waves of confusion throughout Washington, from the Pentagon to the White House itself.
