More staff shake-ups from the Trump administration.

Speaking to reporters at the White House before leaving for Philadelphia for the Army-Navy football game, President Trump announced that chief of staff John Kelly will leave his job at the end of 2018.

Kelly, a retired Marine general has served in the post since July of 2017. Trump and Kelly’s relationship has often been contentious, with talk of him resigning or being fired often in the press, but each time things have smoothed over. This time it appears the relationship can’t be salvaged.

While no replacement has been officially announced, there is much speculation that Nick Ayers, currently chief of staff to Vice President Mike Pence is at the top of the list.
