WASHINGTON — Reince Priebus, the White House chief of staff who failed to impose order on a chaos-racked West Wing, was pushed out on Friday after a stormy six-month tenure, and President Trump replaced him with John F. Kelly, the secretary of homeland security and retired four-star Marine general.
Mr. Trump announced the change via Twitter while sitting aboard Air Force One on a tarmac outside Washington minutes after returning from Long Island. Mr. Priebus, who had joined the president on the trip and never let on to other passengers what was about to occur, stepped off the plane into a drenching rain, ducked into a car and was driven away without comment.
