President Donald Trump says chief of staff John Kelly will leave his job at the end of the year.

Trump isn’t saying immediately who will replace Kelly, a retired Marine general who has served as chief of staff since July 2017. But the president says an announcement about a replacement will be coming in the next day or two.

Trump spoke to reporters at the White House before departing for the Army-Navy football game in Philadelphia.

He calls Kelly “a great guy.”

The West Wing shake-up comes as Trump is anticipating the challenge of governing and oversight when Democrats take control of the House in January, and as gears up for his own campaign for re-election in 2020.
