The circumstances around Rob Porter’s resignation have ushered in another wave of questions about staffing practices in the White House. Internal dissatisfaction with chief of staff John Kelly’s leadership appears to be growing.

Writing in the New York Times on Monday, Peter Baker highlighted the Trump White House’s staggering turnover rate. “More than a year into his administration, President Trump is presiding over a staff in turmoil, one with a 34 percent turnover rate, higher than any White House in decades,” Baker reported. “He has struggled to fill openings, unwilling to hire Republicans he considers disloyal and unable to entice Republicans who consider him unstable. Those who do come to work for him often do not last long, burning out from a volatile, sometimes cutthroat environment exacerbated by tweets and subpoenas.”
